<P> Early in season Gemma is raped by Sons of Anarchy rival AJ Weston and two other unknown men wearing white masks . During the assault, Gemma is told to tell Clay that it will happen again if he does not end his dealings with minorities . Later, Gemma realizes Weston is one of her rapists, when she recognizes his tattoos . When her friend Unser finds her at the rape scene, Gemma demands that he not tell Clay or Jax about the rape so as not to play into AJ Weston and Ethan Zobelle's plans to get Clay and / or Jax to do something rash . Unser complies and further covers up the source of Gemma's injuries by crashing her car into a road divider and taking her to the hospital . The only other person whom Gemma confides in about the rape is Tara Knowles, Jax's girlfriend . Unser later realizes that Chief Deputy Hale is starting to become more involved with Zobelle and his people and tells Hale about Gemma's assault . This causes Hale to re-evaluate his dealing with Zobelle . The rape leaves Gemma with significant and visible emotional trauma, which causes problems in her marriage with Clay . She also feels somewhat paranoid that AJ might try to attack her again . Her paranoia is further compounded when someone from L.O.A.N. mails one of the rapists' white masks to her . </P> <P> When Gemma learns of Jax's plans to become a Nomad, she tells him that she knows about the book her first husband, Jax's father John Teller, had written . She tells Jax she believes John's death may not have been an accident, but rather a suicide . After asking Jax to reconsider his decision, she implores him to read a certain page in John's book, hoping it will give him guidance and perhaps change his mind . The book fails to make Jax decide to stay and when the vote needed to allow him to leave is taken, it passes . Upon learning that Jax still plans to become a Nomad, Gemma calls together her son, Tara, and husband Clay at her home and reveals, fairly graphically, the details of her assault and gang rape . As a result, Jax picks up the jacket patches he had removed from his vest after the vote, which indicates that Jax has decided to stay with SAMCRO . The following morning, feeling unwanted by Clay, Gemma comes on to an emotionally wrecked Tig, who reciprocates her advances, but stops when he sees a picture of Jax and Thomas at the beach as children . Later, Tig is guilt - ridden and proceeds to confess to Opie about Donna's murder . Then, outside the church where Unser's support group meets, Gemma is approached by the priest who runs the support group; he offers her advice to serve others in order to deal with her own self - loathing . Back at the garage, she runs into Chibs, who is distraught about his dealings with ATF agent Stahl . She comforts him and advises him to come clean with the club . After the club meeting, Tig tells Clay, at the end of the day, that Gemma thinks he does not want her anymore; Clay proceeds to the office and shows that he still wants Gemma . When the club goes on lock - down, Gemma looks after other families . She tells Tara she (Tara) does not have to take crap from anyone, because she is the old lady of the Vice President . Gemma has been teaching Tara, because she will one day be the queen of the club . Inspired by Gemma, Tara stands up to her supervisor at the hospital, assaulting her at one point when she calls Gemma a whore . </P> <P> In the second - season finale, Gemma happens to come across Polly Zobelle . Wanting to get revenge and also do her part for SAMCRO, she follows Polly to Edmond Hayes' house . She sends Tara home and sneaks onto the property, where she finds a distraught Polly brandishing a gun . Polly attempts to shoot, so Gemma kills her in self - defense . She then discovers Edmond Hayes' body and ATF Agent Stahl, saying that both of them had a bloody day . Stahl offers to let her leave, but not before tossing her sidearm to Gemma, who catches it . Gemma instantly realizes Stahl's trick to get her fingerprints on the murder weapon, and flees . At a bus stop payphone, she calls Police Chief Wayne Unser for help . She is last seen fleeing Charming with Unser with no idea where to go . </P> <P> Gemma is still on the run at the beginning of Season 3 . Tig is keeping her at a motel until Clay and SAMCRO can figure out a way to clear her name . Clay elects not to tell Gemma that Abel has been kidnapped, because he believes she already has enough to worry about . </P>
