Jackson 'Jax' Teller is the current President and former Vice President of the Sons of Anarchy MC. He is the son of Gemma and John Teller. SAMCRO is the only life Jax has ever known. He lives for his brothers and family, but questions the violent extremes the club will go to for "business." He is the Main Protagonist of the series and 1 of only 3 characters to have appeared in every episode to date.
Jax, the son of Gemma and John Teller, was born in 1978, and raised in Charming, California. His father died in 1993 and his mother later re-married Clay Morrow. He has a genetic heart disorder which he inherited from his mother. His younger brother, Thomas, died of this condition at an early age. He is of Irish and Russian Jewish descent on his mother's side. He carries a KA-BAR USMC fighting knife on his belt.
At the beginning of the series, Teller serves as the club's Vice-President, and works as a mechanic at the Teller-Morrow Auto Shop. He has served time in prison for smuggling and gun-running, his last arrest was in 2003. He married Wendy Case, but filed for divorce because of her drug habit. After Wendy got clean, they reconciled and conceived a son, Abel Teller; Jax left her while she was pregnant because he wasn't ready to be a father. Wendy started using drugs again and Abel was born prematurely in the pilot episode. Jax marries his High School sweetheart, Tara Knowles, in Season 5.
Jax recently discovered several of his father's old journals and an old manuscript entitled The Life and Death of Sam Crow: How the Sons of Anarchy Lost Their Way, which lays out the original manifesto for SAMCRO. Jax finds himself doubting the club's direction, causing friction between himself and his stepfather, Clay, and spreading doubt amongst the other members. Another member of SAMCRO, Opie Winston, has been his best friend since childhood.
Season One begins with the Sons of Anarchy finding their weapon storage warehouse burnt down. The SOA arrive on the scene, where local police officers are already investigating. Jax and Clay talk to Sheriff Vic Trammel about the blaze, who claims that propane tanks inside the building blew up, and suspects arson due to the bootprints both inside and outside. Trammel then shows them the burned corpses of two women hidden beneath the building, who were illegal immigrants. It is later revealed that they were Mexican prostitutes who had sex with the club's Sargent-at-Arms, Tig
When Jax returns home, he begins looking through storage, where finds old photographs of his late father, and a journal entitled "The Life and Death of Sam Crow: How the Sons of Anarchy Lost Their Way" written by him for his sons Thomas (who had already died at the time the journal was written) and Jackson. He is then called away to a group meeting ("Church"), where all of the chapter's members meet. These are Clay Morrow (President), Bobby (Treasurer), Tig (Sargent-at-Arms), Chibs (Medic), Piney (Co-founder), Juice (Intelligence Officer) and Happy. Clay announces that Juice has located the guns, and that they were stolen by the Mayans, a rival motorcycle gang. They decide to go and get some payback the next day, despite Jax suggesting the club looking into other ways of earning money instead of dealing weapons, especially with so many rival groups on their back.
Meanwhile, Gemma finds Jax's pregnant ex-wife, Wendy Case, collapsed in her home, and she rushes her to the hospital. Dr. Tara Knowles tells him that track marks were found on Wendy's hands and feet, and that they had to perform an emergency C-section on her, leaving the baby ten weeks premature. The baby has a heart defect and a tear in his abdomen. The latter is from Wendy's drug abuse, but the former is likely a genetic defect. Together, both defects are near-fatal, and the baby has just a 20% chance of survival. Jax and Tara were high school sweethearts, and she personally requested to help on his case. Jax decides not to visit his son, named Abel, and instead flees the hospital. He then goes to a local bar with Bobby and Chibs, and beats Wendy's dealer, a member of the Nordics gang, with a pool cue multiple times.
Later, Jax visits Opie Winston, a member of the club who was recently released from prison, and promised his wife that he wouldn't return to the club. However, Jax convinces him to ride along with the next day. Jax later goes back to visit Wendy in hospital. Wendy promises that she'll get clean. She also says that the doctors told her Abel is getting stronger, but sho is facing a charge of fetal abuse, and that she has a stash in her drawer at home. She asks him to get rid of the stash before she faces time in jail. Jax turns up at Wendy's house, which he finds his mother feverishly cleaning. Jax tells her that Abel's going to die, which angers Gemma, who slaps him and tells him that he's the only one his son has. Jax asks her about his father's original vision of the club, and she responds that it was to create a brotherhood and a family. Jax tells her about the writings he found and how his father wanted a social rebellion, not an outlaw club. When she leaves, Jax flushes Wendy's stash down the toilet, and takes her gun. Clay and Gemma begin to worry that Jax is abandoning the club and what it stands for. The next day, Clay, Jax, and Bobby meet Ernest Darby, the Nordics' leader, and tell him never to bring methamphetamines or any other drug into Charming again. That night, as they prepare to go and get their guns back from San Leandro, Jax tells Opie not to come because of the situation with his family, and Bobby is occupied performing his Elvis act at a club in Lake Tahoe. When they arrive at the industrial storage warehouse and find the guns, three Mayans turn up in a car outside. Clay and Chibs shoot and kill the Mayans, and another man, who has a number of Nazi and white supremacist tattoos. He was a member of the Nordics, a local skinhead gang, who are allied with the Mayans, and it later emerges that his name was Whistler. Jax was also armed, but hit a mental barrier before he could fire a shot. They escape with the weapons and destroy the building, using explosives.
Wayne Unser, the Chief of the Charming Police Department, has always got along well with the Sons of Anarchy during his time in charge and even employed them as muscle at times. However, he is dying from cancer, and will retire at the end of the month, handing his power over to his Deputy, David Hale, who is overtly suspicious of SAMCRO, and will almost definitely begin an investigation into the club. Hale talks to Jax, telling him that when he becomes Chief, he won't look the other way with the Sons of Anarchy like his predecessor did. To distract the police from their activities, the burnt down warehouse in particular, Jax, Chibs, and Half-Sack (a Prospect in the club) acquire two dead bodies from the local morgue, and set them up in a fake shoot-out. The set-up shooting is made to look like a racist murder involving the Nordics. On his way back to town, Jax was cut off on the road by a man driving a red muscle car. He later caught up with this man at a petrol station, and beat him up. The driver then pulled out a pistol and attempted to shoot Jax, but was wrestled to the ground and then killed by the Pakistani shop keeper, who hit him with a fire axe. The trio then stole the CCTV tapes, and fled the scene. Later, Jax visits Abel, and Tara tells him that he will make a full recovery. She also says that Wendy is being put through sedated detox, and she will be out for a couple of days.
Local businessman Elliott Oswald goes to Clay after his 13-year-old daughter was raped at a carnival, and asks the Sons of Anarchy to hunt the rapist down and kill him, in exchange for money. Clay refuses the money, but insists that if they catch him, he must carry out the punishment himself. Juice and Gemma find out that the rapist is one of the carnies, and the gang capture him and bring him to Oswald, who tries to castrate him, but can't bring himself to do it. Clay then carries the punishment out, but wears gloves whilst doing it. He then blackmails Oswald for the crime, as only his fingerprints are on the knife, because he was about to sell off much of the land around Charming to big business and housing, which would challenge the SOA's reign over the town. Jax is unhappy that Clay did not tell him of the plan, however, and tells him to always inform him on his future motives.
When ATF agent, Josh Kohn, arrives in Charming and began investigating the club, they decided that they should move their weapons to Indian Hills, Nevada, where their brother club, the Devil's Tribe, are based. Clay sent Bobby and Jax to inform the Devil's Tribe that the Sons of Anarchy would be patching over them, and storing guns on their property. On the way there, they came across a group of Mayans on the road, and were involved in a shoot-out, although no one was killed. Later on, the pair ran into a couple as they left a petrol station. The man was extremely disrespectful to the woman, named Susie, and they beat him up. Jax then picked Susie up for sex, and carried on with his journey. When they arrived at the Devil's Tribe clubhouse and informed them of the news, their President, Jury, was not pleased, but eventually accepted that it was the best decision for both clubs. After the patch-over party, Jax went for a ride, and attracted the attention of a group of Mayans. He drew them back to the clubhouse, where the Sons of Anarchy were waiting for them. A large shoot-out ensued, during which Jury was shot and injured. After having sex with Jax, Susie left, and went back to her old boyfriend. Josh Kohn had been following Jax the whole time, taking photographs, and saw the shoot-out. He sent a picture of Jax and Susie having sex to Tara, who is revealed to be his former lover.
Otto and a number of other imprisoned SAMCRO members have been protecting Chuck Marstein in Stockton prison. He is wanted by the Lin Triad because he stole money from them, then informed on a number of their members when he was arrested. When Clay and Jax went to visit Otto in prison, he told them that if they protected Chuck when he was released, he would inform them on where the Triads keep their money. They agreed, and picked him up from prison, and brought him to the clubhouse. SAMCRO intended on waiting until the restaurant, where the money is stored, was closed until they raided it, but Chuck's frequent unconscious masturbating was unbearable for them, and they decided to raid the restaurant straight away. At the restaurant, Jax used his knife to cut open a newly-plastered patch on the ceiling, where the bag of money was. However, just after they stole the money, and some counterfeiting plates, the Triads turned up. Instead of starting a war, Clay decided to make a deal; SAMCRO handed over Chuck and the plates, and the Triads gave them $60,000. Meanwhile, Kyle Hobart, a disgraced former SAMCRO member, went to Jax and asked him if the Sons wanted in on his deal selling stolen car parts. Jax accepted, and invited him to the clubhouse that night. This was a set-up, however, to punish him for not having his SOA tattoo removed after being disowned by the club. At the clubhouse, they tied him up and Tig used a blowtorch to burn off the tattoo.
Jax and Piney sold five AK-47s to Nate Meineke, Piney's old war buddy, and his right-wing state Militia. They used these guns to ambush a prison convoy, to free one of their members, Frank Cison. Three police officers were killed during the assault, during which Meineke dropped his cell phone, and his last calls had been to Teller-Morrow. When the ATF found the phone, they arrested Clay and raided the clubhouse. Clay was later released because no evidence was found, meaning he could no longer be kept in custody. Meanwhile, Jax, Piney, and Opie decided to kill Meineke and his gang to stop them from "snitching" if they were apprehended by the authorities. They pretended to sell them more weapons, but the boxes of guns were actually filled with explosives, and the militia loaded their trucks with them. All of the militia were killed when the bombs were detonated.
When Tara told Jax that ATF Agent Josh Kohn had been stalking her, he threatened to kill him if he went near Tara again. He also reported him to David Hale, who in turn informed the ATF. Upon learning that the authorities have not yet apprehended Kohn, he went and hunted for him himself. He found him at the local barber shop, and a brawl ensued, with Jax emerging the victor. Kohn was then arrested for breaching his restraining order on Tara.
While riding his motorcycle on the highway, Jax came across a truck driver on the hood of his truck. The driver had crashed his semi while he was high on meth. The Nords came to his hospital room and beat him, after which the trucker told the Sons that the Nordics had beaten him, because he owed money to them. They also later took his truck and tanker full of diesel. Jax and Opie hijacked the truck back from the Nords, and sold it to Wayne Unser, who runs a trucking company. This gave SAMCRO enough money to buy weapons from the True IRA. Later that night, he went to Tara's house after she phoned him and asked him to come over. Kohen had broken in and tried to rape her, but she grabbed his gun and shot him in the stomach. Jax killed him, and had sex with Tara, next to the body.
Cameron Hayes, a member of the True IRA, offered SAMCRO a free shipment of guns if they carry out a hit on Brenan Hefner, the man who killed his cousin Michael McKeavey. Jax, Bobby and Opie went to the hotel room, where Hefner sees his African American mistress. Opie was supposed to shoot him when he left the room, but froze, so Bobby stepped in and shot him at close range with a silenced pistol.
The ATF arrested Luann Delaney and Cherry, the women of Otto and Half-Sack, and threatened them with prison if they did not give information on SAMCRO. Bobby, Piney, and Tig started a brawl at a local bar, and most of the town's small police force had to go to the scene to break it up. This gave Jax and Opie an opportunity to break into the police station, with the help of Unser, to give Luann a message to give to Otto. Cherry said she would rat if they didn't get her out, so he took her with him. Luann stayed behind because the ATF were about to get Otto to plead to a case that he thought was harmless, to secure him and Luann a deal, but in fact would lead to the arrest of every club member.
When Bobby was arrested for the murder of Brenan Hefner, Agent June Stahl made it seem like Opie was the one who identified him. Jax never told Clay and the other club members that Opie failed to shoot Hefner, forcing Bobby to shoot Hefner from the other side of the door, where the girl saw him. Still thinking that the Hefner shooting went down clean, and thus the only people that could have seen were the other SOA members, along with all the evidence engineered by Stahl, it seemed extremely likely that Opie was the rat. Jax defended him, however, and convinced some of the club that the ATF had set him up. Clay had Tig check Opie's car for wiretaps, and he found them. Tig and Clay were convinced Opie was guilty and decided to kill him.
Jax began living at Tara's house, or at least sleeping with her on a regular basis. When he and Tara were kissing at the hospital, Wendy saw them, and later confronted Tara. The next day, Jax went with Clay, Tig, and Opie to make an arms deal with the Mayans in Oakland. The One-Niners attacked the deal, however, and they escaped, while the Mayans and Niners fought it out. Clay and Tig had made a deal with the Niners, but didn't inform Jax or the others; the Niners were supposed to eliminate the Mayans after SOA left, but they decided to take them out also. Later that night, Abel was released from the hospital, and a party was held in celebration. Tara again kissed Jax at the party, purposely in plain view for Wendy to see. When Jax asked Tara why she did it, she slapped him, and left. When Opie left the party, he took his wife's car to take his children home in, and his wife took his pick-up truck. Tig thought it was Opie driving the car, and shot Donna Winston.
Wendy told Jax that she wants to give their relationship another chance now that they have a child, but he refused, saying that things will be no different than before. When he later went to visit Tara, she told him that she was afraid of being caught for killing Kohn, and that she is moving back to Chicago. He admitted that she is the only woman that he has ever loved, and that he only married Wendy because he was lonely. At Church, Piney said he wanted to kill Laroy, as revenge for killing Donna, so Jax told Half-Sack to follow him, and make sure that he doesn't do anything unnecessary. Half-Sack called and said that Piney had gone into a bar in Oakland, where he was holding a Niner hostage. When Jax and Chibs got there, they managed to get Piney out, and had a talk with Laroy, who said it wasn't his gang who killed Donna. When he visited the police station to ask Unser if he had any leads on Donna's killing, David Hale approached him. He told him about Stahl setting up Opie, and Jax realized that it was SAMCRO who killed Donna. He confronted Clay about this at the clubhouse, and asked him if he had anything to do with Donna's death, and Clay denied it. As Jax left the clubhouse, Juice told him that the witness to Hefner's killing is a 17-year-old girl, and that Chibs, Happy, and Tig are on their way to kill her. Jax drove out to San Joaquin on his motorcycle, and stopped Tig from killing her at gunpoint. He told Chibs and Happy to leave, and threatened the witness into leaving the state. He fought with Tig, because he killed Donna. Jax spent the night in the graveyard drinking vodka. The next morning, he went to Donna's funeral, which was attended by Sons of Anarchy from all across the country. He and Tara shared one last kiss, and the Season ended as he stood and looked at his father's and brother's gravestones.
In the first episode of Season 2, Jax and Clay go head to head over the death of Donna. The only reason that Jax does not tell Opie the truth is because he loves Opie too much. He insists on coming with Opie, Chibs, and Tig to murder a Mayan member who SAMCRO frames for Donna's murder. After the Mayan is killed, Opie carves the Sons of Anarchy symbol into his stomach (so the Mayans would know why the man was killed). Jax removes the symbol and disposes of the body in Mayan territory, putting up 9 fingers to make it look like the Niners killed the man. Jax has gotten a new tattoo: his son Abel's name on his left peck. He is seen saving Tig from bounty hunters with Chibs, Happy, Half Sack, and Piney. He assumes that Ethan Zobelle and L.O.A.N. will fight an under-handed war against SAMCRO and he is against Clay's plans to strike at the Aryans head on.
After L.O.A.N. burns down Cara Cara, Jax suspects it was Clay, since Clay did not want the porn business around after Luann Delaney was murdered. This drives Jax over the edge, and he decides to go Nomad. The vote is unanimous and Jax goes Nomad, but after learning of his mothers rape at the hands of L.O.A.N., he comes back in as the Vice President of SAMCRO wanting revenge on L.O.A.N., specifically AJ Weston. After finding out that Tig told Opie the truth about Donna's death, Opie leaves the clubhouse looking for Stahl. Jax assumes that Opie will be after Zobelle and his crew, and goes off to follow Zobelle. While following Zobelle, Jax learns that Zobelle is dealing with the Mayans for their heroin behind Weston's back.
In the Season 2 finale "Na Trioblóidí," Jax finally gets revenge on A.J. Weston by killing him in a tattoo parlor bathroom. However, at the end of the episode Cameron Hayes, who mistakenly thinks Gemma killed his son, kidnaps Jax's son Abel and flees on his motorboat to an unknown location. Jax is last seen distraught and crying on the docks while Clay and the other Sons console him, watching Hayes speed off with his son.
The season begins with a distraught, complacent Jax in Abel's nursery. It is obvious he has taken his son's kidnapping hard, and eventually Clay and other members come to his house to help him. Tara is at a loss at what she can do to help Jax, Clay however tells her how helpful she has been. They continue to track leads on Abel. The entire club, including Tara have decided not to tell Gemma about Abel's kidnapping. During Half Sack's funeral, personally and politically, Jax has to pull it together. But Jax's heir apparent role isn't a voluntary one, as much as he loves and relies on the men around him. Jax's conflicting desires for connection and freedom tug at him. His encounter with Piney at the graveyard reminds him of his many personal losses (a father and brother dead, a child missing), but Jax's murderous rage at Half-Sack's funeral is just as believable as his impotent grief. In that moment at the end of 'SO,' his rage as a club member and as a father come together, and for once, the distinctions don't matter. At the end of the episode, there is a drive-by shooting. Spotting a young boy that has been shot, Jax loses it.
Those connections between Jax and Tara haven't been severed, but they're fraying. Gemma's on the run, and as she slowly goes mad in a motel, Clay has to lie to her about her own grandson. Jax and Tara reunite. Gemma reunites with her father, Nate Madock.
Jax continues to channel his rage into the desperate search for Abel, and Clay continues to encourage that. Still searching, Jimmy O spins lies to Jax about Abel's whereabouts; he thinks he's in Canada.
Clay, Jax, Tig, Tara and the rest deceived Gemma for what they thought were good reasons. Father Ashby needs someone to come to Belfast looking for Jiimmy's head on a platter. And that person is Jax Teller. Once SAMCRO comes to Belfast, Jimmy will have very big problems indeed. After confronting yet more obstacles in his search for his son, Jax Teller, a man who still has the occasional impulse-control issue, doesn't take the violent path. He thinks up a clever scheme that will give him time to find his son, take care of club business and, most importantly, help Gemma. And if the deal goes down, Stahl will get out of the DEA doghouse and Maureen Ashby will have one less problem to deal with in Belfast.
Jax knows in his heart that he has to take Tara off that path. She's in love with Jax, not the club and the life. Given the opportunity to support the club—or, more accurately, support her man—she'll do it every time, but Jax doesn't want her to get those opportunities. He doesn't want her to have to try to change herself to fit into the world of the Sons.
And with Abel still very much in danger, he can't handle the idea of another loved one being in harm's way. As much as he loves Tara, he breaks it off with her for good. Unlike last time he tried to cut her out of his life—at the start of the season, when he was filling up the hole inside him with alcohol and self-hatred—she fought back and she won. This time, Tara didn't even say a word.
This is a different Jax; this is a resolute man who is mentally arming himself for battle. He can't both worry about Tara and fight a war in Belfast, so he has to pick. He ends up following Clay's advice, in a manner of speaking—he finds a sexual outlet with the porn actress, Ima, who's been hitting on him. It's an uncomplicated relationship, but it still brings its own share of pain. At the end of the episode (The Push), when he was in bed with Ima, he looked like a man exorcising a painful memory. There was nothing intimate about that moment.
Now that the club is going over to Belfast, many more revelations and betrayals appear to be in the offing. Jax eventually discovers that Trinity Ashby is his sister as well.
Kellan Ashby hit Jax Teller's most vulnerable spot hard when the priest talked about how painful it could be for a child to grow up in "the life." Jax himself grew up in that life, embraced (or trapped) in the almost paralyzing, clannish world of the MC. For years, he'd harbored doubts about whether living life for and with SAMCRO was the wrong path for him. And now here's Ashby, echoing things that John Teller wrote in the manifesto that carried such weight with his son. Ashby is a liar and a manipulator, to be sure, but that doesn't make his words sting any less. John never wanted this difficult life for his sons. Jax has been looking for Abel all season, but, once he found the child, was he making a huge mistake by letting him come of age in the same world he found so brutal and off-putting at times? Once Gemma put some sense back into Jax however (even telling him Tara is pregnant), they were able to get Abel and leave Belfast. Before leaving Belfast however, Jax get's a call. He hears news that Tara has been kidnapped. Arriving back in Charming, Jax is able to save Tara, and the two reunite. Three-quarters of the way through the finale, when Jax Teller took Tara to his mother's house, and Tara took Abel in her arms, Jax finally allowed himself a half smile. It was one of those blink-and-you'll-miss it moments—it was not a moment that called attention to itself.
Once Jax and SAMCRO return from Belfast, they begin looking for Tara. The Mayans help in the search because Salazar is a threat to their new heroin operation in Stockton Prison. They find two women dead in the road. One is Salazar's girlfriend and the other is a woman Salazar killed for her car. Jax is worried about Tara's safety and Bobby promises him that they will bring her back safely. They discover that Salazar not only has Tara, but has taken Hale hostage as well. When Salazar reveals that he will trade Tara for Jax, he is ready and willing. Jax proceeds to get in a fight with Salazar. Salazar runs, only to end up cornered in the hall where Jax stabs him to death and makes it look like self-defense. Later, he goes with Tara to an ultrasound to make sure the baby is healthy. Jax later meets with Stahl who is still determined to see the deal through. In the finale it is revealed that his dealing with Stahl was set up by the club, when they were let in on his plans is not clear at this point. When she inevitably reneges on her promise of secrecy he acts the part knowing that she will soon be dead and they will serve light time. In a letter to Gemma, Jax assures her that he is not his father and would never rat on the club. However, in a letter from his father to his mistress Maureen Ashby read by Tara after the club is arrested, it is intensely suggested that Gemma and Clay were responsible for his death, knowledge of which may prove to change him.
Jax and the other members of the club are released from prison. He has abdominal scars stemming from a prison stabbing incident involving the Russian Mob. Also, Jax's appearance is different. He has cut his hair and trimmed his beard.
After he returns home to Tara and their two sons, Abel and newborn Thomas, they make love. During a post coital discussion, Jax proposes to Tara, with the ring wrapped in the tiny fist of his second son, Thomas, which she accepts. The newly-engaged couple then have a discussion about their future as a family, in which Jax admits to wanting to leave the Sons once Clay has stepped down as President. Later, he attends Opie's wedding as his best man, and fter the ceremony, Jax goes with Clay and the Russians to shoot a gun given to Opie as a wedding gift from the Russians. While Clay is testing the gun, he shoots Putlova's bodyguards, and Jaxs stabs Putlova to death in revenge for trying to kill him in prison, saying it's "just business". Jax then returns to the reception to dance with his fiancee, Tara. The next day, Jax and Tara are having breakfast with their sons, when they see on the news a story about four dead bodies found at the construction site of Charming Heights. Tara asks Jax to tell her all he knows about it, and he tells her that it was retaliation for him getting stabbed in prison. After breakfast, he goes with Clay to the deal they set up with the Galindo Cartel, were they meet Romeo and Luis. At the deal, Jax learns that Clay has set it up for SAMCRO to mule cocaine for the cartel and the Mayans. Clay tells Jax that everything that has happened the last two years has left him and Gemma with no money, and that he needs Jax to help him sell it to the rest of SAMCRO. Jax tells Clay that he will back him as long Clay lets Jax out of SAMCRO, and that the President's patch goes to Opie, and Clay agrees to the deal. Jax and Clay have a meeting with the rest of SAMCRO to try to convince them that the drug transporting would be good for them financially in which Jax shows them the money they made from the first deal to convince them. After the meeting, Jax and Opie go to the Indian Reservation to see about the ammunition, where they are encountered by some vengeful Russians. The Russians threaten to kill two Native American women they are holding hostage if they don't get their guns returned. After a scuffle, Jax agrees to call SAMCRO to get their guns to them. Jax and Opie are eventually rescued by the Galindo Cartel, who kills all but two Russians, one of which was given to the Native Americans for retribution. When he and Opie return to the Clubhouse, they find out the clubhouse was wrecked by Sheriff Roosevelt. To lighten the mood, Tara announces her and Jax's engagement. During the celebration, Jax and Bobby met eyes from across the room, and Bobby pours some expensive tequila out onto the floor, signifying resepct for Jax's deceased father, John Teller, who could not be there for the family celebration.
Jax, Opie, Happy, Tig, and Kozik all struggle to try to find the guns that were stolen from Kozik by some kids, who challenged him to a basketball game, and stole them after attacking him. They first ask a French fence by the name of Vivica, who denies having any knowledge of where the guns are. When they find the ones who stole the guns, they are led back to Vivica, where it is discovered her sons were the ones who had them. They get the guns back and head to the clubhouse to vote on muling drugs for the Cartel. It passes, with a close vote of 6-5. When SAMCRO goes on a run to complete the gun sale, and get ready for their first drug transportation, they are aided by their Tucson charter, SAMTAZ, who they discover are cooking and selling crank. SAMCRO shows disapproval, and at a meeting at the SAMTAZ clubhouse, they try to convince SAMTAZ to stop dealing, but to no avail. They eventually track down Reggie, who left the club, and discover that the SAMTAZ V.P. and Sgt. at Arms have blackmailed him into leaving, and murdered his sponsor, Little Paul, to get their crank business voted in. After SAMTAZ learns about this, the V.P. and Sgt. at Arms are beaten up and excommunicated from the club. SAMCRO meets up with the cartel and delivers their guns, then prepare to mule the drugs back to Northern Cali. When the drugs arrive, they leave them stored in the gun warehouse. Jax then returns home, where he shows Tara the money he received, and instructs her to put the money in a safety deposit box. Later, Jax and the club try to track down Georgie Caruso for his involvement in Luanne's murder. When they find him, they come close to killing him, until they learn he access to Japanese investors, who can help them shut down Charming Heights. They keep him alive to get the Japanese to help, but still plan to kill once Charming Heights is gone. The next day, Jax discovers that Opie has slept with Ima, and the reason was due Lyla taking birth control. They later head to the warehouse, were they discover a kilo of coke was stolen from the drug load. SAMCRO suspects one of the prospects, and spends most of the day interrogating them. Jax and Opie later get a call, saying Ima pointed a gun at everyone in the clubhouse, after Lyla discovered that she had sex with Opie. When they get there, Jax is put in a bad spot with Tara, after she is reminded of the fact that Jax also had sex with Ima while Abel was missing. After the domestic problem is handled, Jax and Opie return to the warehouse, were they are told that it was Miles who stole the cocaine, and that Juice killed him and retrieved it. After the business transaction is done, Jax meets up with Ima under the pretense of wanting to have sex, and slams her face into the table, then warns to stay away from SAMCRO and his family. The next day, Jax and SAMCRO goes to a cut and bag operation of the Mayans, when Jax receives a call, telling him there has been a death threat made against Tara. The Mayan's drug operation is then attacked by gunmen, who they later confront, and discover they work for the Galindo Cartel's rival, Lobos Sonora. Jax later talks with Tara, who learns of the drug business, and voices her disapproval. Later, when SAMCRO has meeting to about how to handle the things that have happened, Bobby calls for an official challenge to have Clay removed as President of SAMCRO. The next day they prepare to vote, only to have their clubhouse shot up by Lobos Sonora, during which, they leave a bag of heads, one of which belongs to Armando, the SAMTAZ President. A Lobo was shot by Filthy Phil, and taken to warehouse, were he was tortured by Happy, but was unable to get him to talk. Luis eventually shows up, and injects the Lobo with truth serum, which makes him confess that there is a rat in the Mayans. Jax eventually goes to the cabin to apologize to Piney for backing the drugs. They have a discussion, were Jax tells Piney that he is done with his father's ideas, and Piney still defends John's actions. Later, SAMCRO, the Mayans, and the Galindo Cartel prepare for battle with Lobos Sonora, who leave a truck of headless bodies. Jax and Tara agree that she should take their sons and get clear of the violence taking place.
The next day, SAMCRO meets with Galindo and the Mayans to figure how Lobos Sonora gained a California network. They find out that the One-Niners may have become a costumer of the Lobos. They set the Niners up to meet the Galindo Cartel, and are forced to have the Lobos walk into a trap, which fails. Luis is close to killing Laroy and the Niners, until Jax steps up, and convinces Luis to spare them. Jax later is confronted by Bobby, who tells Jax that he knows about Jax's plan to leave SAMCRO, and tries to convince him not to go, because he is the best man to lead when Clay is gone. Jax later confronts Clay about breaking his promise not to tell anyone that Jax plans to leave. Jax also tells Clay that he is going to go through with one last gun deal, and help the club find a way to get free of the Cartel, and then he is leaving. After this discussion, Clay crosses the line by insulting Tara, and Jax tells him to never do it again, or he will damage Clay's already fragile hands. He decides to tell Tara that he will escort her and the boys to Oregon, and that he is out of the club. The next day, the Teller family are on their road trip, having a good time, until someone tries to abduct Tara. Jax is able to rescue her, but her hand is badly damaged in all of the excitement. After she taken to the hospital, SAMCRO and the Mayans go to talk to the One-Niners, to get information about how to contact Lobos Sonora, only for a Mayan and a Niner to end up dead. Jax goes back to the hospital to be with Tara, where he learns the extent of the damage done to her hand. His guilt grows after he sees that Tara has lost all hope of them ever getting out of SAMCRO and Charming. He later has an intense conversation with Opie, were Jax admits that he wants out of SAMCRO, and he admits that he should have let Opie leave when he wanted out, and that if he had, Donna might still be alive. Jax then gives Opie a heartfelt apology for the things that have gone wrong in his life. The next day, Jax sees Tara in the hospital, and though she has calmed down, she still shows doubt in their ability to leave SAMCRO. Later Jax sees that Clay has beaten Gemma, and this greatly angers Jax. During the conversation, Jax is asked by Gemma about his plans to leave, and he is forced to tell her the truth. Jax later confronts Clay about what happened to his mother, where Clay tries to hide behind club rules, by saying it is between him and his old lady, but Jax tells Clay he is not getting off that easy, because Gemma is still his mother. They go off to help the cartel deal with the remaining Lobos that are in Northern Cali. There is a battle, and some of SAMCRO stranded in mine field, where Kozik is killed after stepping on a mine. They are able to draw out the rest of the Lobos with rocket launchers, and kill them. After it is over, Jax sees Juice putting his life in danger by walking casually across the field, likely another suicide attempt, and later tells Chibs to talk to him. SAMCRO then gathers to together to discuss business, and give tribute to Kozik. Jax and Opie have another talk about Jax's discussion to leave the club. During this conversation, Opie reveals that he didn't stay because of what Jax said, but because he knew that he was an outlaw, and trying to be anything else would be living a lie. Jax apologizes to Opie for lying to him, and Opie continues to show his disappointment. In To Be, Act One, Gemma finally reveals the letter to Jax, angering him and vowing to kill Clay with a blood thinner, given to him by Tara.
In To Be, Act 2 (the season finale) Jax does not kill Clay, as he needs Clay alive for the Galindo Cartel/CIA deal. Instead, he threatens Clay, and tells him that he will be stepping down as President, thus making Jax SAMCRO's new President. He removes Clay's President patch from his cut, and Clay suggests Jax kill him, but he tells Clay that he is already dead, and spits in his face. Jax calls a meeting, and everyone attends except Opie. His first act as President is making Chibs his new Sergeant at Arms, and the episode ends with Jax banging the gavel, Tara standing behind him, with her arm over his shoulder, mirroring a photo of Gemma and John Teller.
Three weeks have passed since Jax was patched in as President. A gun run for the Gallindo Cartel goes wrong when the One-Niners caused the gun truck, driven by newly patched in Phil, to crash and flip, leaving him trapped as the One-Niners torch the truck as retaliation for the murder of Oakland Drug King Damon Pope's daughter, who was accidentally killed by Tig when he sought revenge for the shooting of Clay and failed to kill One-Niner leader Laroy, but instead her. The Galindo Cartel orders a meet between Damon Pope and Jax Teller to settle their differences, where Jax is nearly killed by the new leader of the One-Niners, Darnell, after surprising him with a gun with no bullets, after which Jax destroys him. Pope's right hand kills Darnell to demonstrate Pope's power, and appoints Tyler as the new leader. Jax later finds out that there is an arrest warrant for him, Chibs, and Tig since they were seen by witnesses the day of Veronica Pope's death, so they are forced to go into hiding at Nero Padilla's day spa until they figure out their next move.
Jax rides a 2003 Harley Davidson Dyna Super Glide Sport. His bike features a black powder coated engine and a tape wrapped exhaust. Like most of the other members with Dynas, Jax's bike has the front drag fairing. His fuel tank sports the reaper, fading towards the back of the tank. He has custom T-Bars with high risers for handlebars.
In Season 5, episode 6 Jax is shown riding a street glide when the sheriff's deputy tried to run them off the road.
In Season 5, episode 8 Jax and Chibs have new dynas with led lighted mirrors.
Jax is calm and collected most of the time but is easily angered and has no remorse in killing. Some fans say he is one of the most sensible members of SAMCRO, while others think his decisions are questionable or self-serving. Jax is also more headstrong than the other members.
