Wendy Case is Jax's estranged wife and the mother of his son, Abel Teller. She is a recovering drug addict who used methamphetamine during her pregnancy. After learning the reasons for her grandson's birth defects, Gemma gave her drugs and the instructions to commit suicide via overdose. Gemma threatened that if Wendy did not obey, she would use her ex-daughter-in-law's drug addiction to ensure she never have any contact with Abel. Wendy went to rehab and spent time in a sober living facility. She longed to reunite with Jax, believing that the stability of her family would assist her recovery. Gemma, desiring to destroy her son's relationship with Tara, promised to help Wendy reunite with Jax. After a rift between Tara and Jax and the murder of Donna Winston, Jax and Wendy reconciled and were seen making love. She was last seen at Donna's funeral watching Tara kiss Jax. However, while Jax was in Stockton, Wendy signed full custody (guardianship) of Abel over to Tara.
Wendy returns to Charming with the intention of getting to her son. She says Abel deserves to know the truth. "Out of respect" she asks Tara's permission first, causing Tara to have a bit of a breakdown. Wendy uses the argument that she is a recovered addict who turned her life around and would probably be seen as the most stable adult in Abel's life if she should chose to pursue custody; giving Jax and Tara the ultimatum to let her see Abel or risk losing him all together. She's gotten much more calculating, and may prove to be a force to be reckoned with in future seasons. Wendy is later seen at Jax's home. Chuck Marstein answers the door and informs Wendy that Abel is in his room. Wendy walkers to Abel's room where she is met by Gemma.
