Tara was Jax Teller's high-school sweetheart, and during that era she had a crow tattooed on her lower back representing her connection to SAMCRO.

Tara's relationship with Jax upon her return to Charming is based primarily on their mutual concern for gravely ill Abel.

Her psychotic ex-boyfriend Agent Kohn comes to Charming under the pretext of investigating SAMCRO, but is really there because he wants to resume his relationship with Tara.

Jax stabs Kohn's car on her behalf, beats him bloody in an altercation at Floyd's barber shop, and then escorts him out of town.

When Kohn returns in the dead of night and attacks Tara in her home, she shoots him in the gut and calls Jax for help.

Tara and Jax then fall into each other's arms and make love while Kohn's iPod plays the Andy Williams song "Can't Get Used to Losing You" on a continuous loop.

Tara spends more time with Jax at the clubhouse, plays nice with Gemma, and works to heal wounded club associate Cameron Hayes.

In the final episode of the first season, "The Revelator", Tara tells Jax that she has arranged to return to Chicago as she does not believe she is cut out for life in Charming.

Later, Margaret files a "hostile work environment" complaint against Tara after Gemma confronts the administrator about the hospital's desire to move Chibs to another facility because of an insurance issue.

She tells Margaret, "I know where you live, I know where your kids go to school" and informs her that the cops are on SAMCRO's payroll and that the club runs Charming.

In the closing minute of the season 3 finale, Tara reads letters from John Teller to his mistress Maureen Ashby implying that Gemma and Clay would be responsible for his death should it happen.

In this appisode, Tara goes to Piney for information on John Teller's death but is rebuked and told not to investigate further and that the past was "dead and buried" .

In another special "appisode" (titled: Second Son) - which bridges the gap between seasons; Tara and Gemma visit Jax in prison.

He does assure her that as soon as Clay retires and once he has saved enough money to avoid living off his wife he will leave SAMCRO and they will start fresh as a normal family.

The next day Tara and Jax 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.

This plan fails as Jax is forced to stay due to the influence of Romeo Parada and Luis Torres who are undercover CIA agents.

Tara mocks the romanticism of a spontaneous wedding at Diosa to which Jax jokes, "I killed a Fed for you ... nothing says endless love like capital murder."

Tara extends an olive branch to Gemma by placing her on daycare visitor's list and allowing her to watch the boys.

Tara cuts her out of the family, but agrees to let Gemma back in if she helps Jax with getting intel from Clay on plot to undermine his leadership.

Tara's career is on the line when she is investigated as an accessory to Otto's brutal murder of a prison nurse that was killed with Luann's crucifix.

Wendy confronts Tara with reality of risk associated with MC and shows her the shoulder bruise from the force of Jax jamming a speedball needle into it.

The prison nurse's brother, Lee Toric, confronts Tara at the hospital and threatens to avenge her death.

Gemma threatens to tell investigators that Tara planned the killing of an innocent nurse to reverse RICO.

She tells him she accepted a job offer in Oregon to spare them from becoming like Gemma and Clay, which will force the boys to relive their mistakes.

Jax is seen at the end of episode 1 cheating on Tara with Colette Jane, an escort handler) Tara finds herself at odds with everyone she was supposed to be able to trust and chooses to use the bullet she pulled from Bobby Munson's shoulder as evidence necessary to grant her witness protection, in turn making her a rat and a liability to the MC and to Jax himself.

The two come to an understanding and Jax surrenders himself to the mercy of DA Tyne Patterson in exchange for Tara's immunity for all the crimes she committed on behalf the MC, specifically that of the murder of Pamela Toric, for which she was accused in season 5 but did not have anything to do with.

Tara and Jax agree to meet the DA at the Teller home at 6pm after he spends his last hours as a free man with his sons.

Stunned and heartbroken, he drops his gun at Roosevelt's feet and begins sobbing as he cradles Tara in his arms.
