Gemma Teller Morrow (née Madock) is a fictional character on the FX television series Sons of Anarchy, played by Katey Sagal.
Gemma is the widow of John Teller, a founding member of the Sons of Anarchy Motorcycle Club Redwood Original (SAMCRO).
According to Police Chief Wayne Unser, she left Charming when she was sixteen and returned "ten years later with a baby and a motorcycle club".
Many of SAMCRO's plans succeed because of Gemma's quiet intervention (e.g., finding out who raped the little girl at the carnival in the episode "Fun Town", and surveillance of L.O.A.N.
Early in season 2, Gemma is raped by Sons of Anarchy rival AJ Weston and two other unknown men wearing white masks.
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 rape leaves Gemma with significant and visible emotional trauma, which causes problems in her marriage with Clay.
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.
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.
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.
Tara and Tig inform the club that Gemma has disappeared, and Jax realizes that she was heading home to be with Abel.
She makes up her mind to go to Belfast with Clay and Jax, and employs Tara's help in breaking out of police custody.
When they are all in the van, Gemma forces a SAMBEL (Sons of Anarchy Belfast) member to run the police off the road.
After SAMCRO's release from police custody, they head to the SAMBEL clubhouse, where Gemma meets Maureen and Trinity Ashby.
When father Ashby shows up, it is revealed that Sean Casey was tortured, and the priest tells them that Jimmy is now after Abel.
Once back in Charming, the club is trying to find Tara, and Gemma is struggling with the deal Jax made with Stahl.
When she sees that the deal is still on, and Jax is giving up the head of the IRA, she tries to turn herself in, only to find out that it is too late, because Stahl already gave her statement clearing her of the killings.
But Gemma gets some relief after Jax sends her a letter explaining that he was never a rat; the deal was a trap the entire club was in on, and the only reason they didn't tell her was to keep her from being an accessory if things went awry.
When the club goes to Tucson for the drug run, she confronts Piney about his beef with Clay and tells him to let it go before he gets himself killed, but he won't back down.
Later in the season, Gemma discovers Piney's dead body and immediately knows it was Clay who killed him.
Later she and Clay talk about the situation and she tells him that they will simply add Piney's death to their list of secrets and she will convince Tara to give her the letters.
Later, Gemma burns the letters that implicate her in John's death and when the men are having church she sees Jax at the head of the table and Tara standing behind him.
Once she arrives at her home she catches Clay digging through her belongings, claiming to be looking for a ring, then he asks for a moment of Gemma's time and after hearing him out, he tries to touch her and she drops him to the floor warning that he will never lay a hand on her again.
During the time Gemma is separated from Clay, she goes out and gets drunk and does drugs, one time, when Jax and Tara decide to go to the cabin to be alone, Jax insists that Gemma keep the boys, she agrees to do so, when she is driving, she drives under the influence of Marijuana and her vehicle goes off the road, injuring Abel in the process.
As they are ready to leave, the police show up and arrest Clay for murdering Damon Pope, Gemma lies saying he went somewhere.
Throughout Season 6, Gemma struggles with keeping her family intact and works to stop Tara from leaving Charming with Abel and Thomas.
He reveals the truth to her that Jax planned to surrender himself to the authorities so that Tara could attain immunity for her role in the murder of Pam Toric and be allowed leave Charming with their children to start a new life.
As Abel struggles with Tara's death, he overhears Gemma tell Thomas that she was sorry for killing her, which torments him into cutting himself as a result.
Jax learns the truth from Abel that Gemma killed Tara, which forces him to confront Juice in prison, who confirms that it is.
After Juice calls Gemma to let her know what he told Jax, she leaves Charming and also Nero behind, but not before going to see Abel and giving him the SOA rings, in hopes of him one day joining the biker gang.
