- "Let me and my boys do it... Just tell me who."
- ―Esai Alvarez to Marcus Alvarez
Esai Alvarez goes with his father to meet with Ernest Darby, the leader of the Nordics. Darby wants the Mayans to kill SAMCRO President Clay Morrow in exchange for information on their IRA contacts. Marcus wants to kill Clay and also Darby, and Esai offers to carry out the hit. That night, he and another Mayan shoot up Darby’s home, killing a Nord and the two women they were with, though Darby escapes with his life. His men's simultaneous attack on Clay is also a failure ("The Pull").
Later, Esai meets with his father at the park. Marcus tells him that he isn't disappointed in both of the hits failing because it allowed him to sit down with SAMCRO and make a deal with them, allowing the Mayans to buy guns. They get some churros and Marcus hugs his son and says, “I love you, mijo.” A second later, unbeknownst to Esai, the churro vendor turns and stabs the back of his head with a knife killing him. Marcus then pulls out an envelope filled with cash and hands it to the vendor.
