<P> At the beginning of Season 4 Tara is waiting to greet Jax on his return home . When Jax arrives he and Tara spend a little time with Abel and Thomas before Jax has to go inside the clubhouse for a meeting . When Tara and Jax meet at their house later, they waste no more time and begin making love . Jax then proposes to Tara by putting a ring on their son Thomas's finger . Before Tara can fully accept they have a serious talk about the future of their family . Jax explains that he is done with SAMCRO, but he has to stay until Clay steps down as president because he and Gemma won't let Jax walk away without conflict . 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 . </P> <P> Later, at Opie and Lyla's wedding, Jax is the best man and Tara is the maid of honor . 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 . She asks Jax to tell her all he knows about it . He tells her it was retaliation for him getting stabbed in prison . Later on she encounters Gemma in her office who asks why Tara is not wearing her engagement ring . Tara simply tells Gemma that she and Jax are just waiting for the right time to tell everyone . Later at the clubhouse a distraught Tara is reunited with Jax after he is rescued from the Russians . There she discovers, along with Jax, that the clubhouse had been trashed by Sheriff Roosevelt . To lighten up the mood she decides to announce the engagement . </P> <P> During the season (and before) Tara has become more fearful of the consequences of being involved with SAMCRO and increasingly begins to think about the effect it will have on her son . This leads Tara to make the decision of leaving town with her son until things settle down . Tara is also conflicted about the letters from Maureen Ashby . Gemma has found out she has them and tries most of the season to obtain them and destroy them . Piney also shows interest in them as a way to blackmail Clay, but Tara keeps them protected . Clay finds out about the letters and he is so fearful of them getting out, that he takes out a hit on her life from Romeo . Eventually after confronting Gemma about the letters, Tara admits that she is not capable of showing the letters to Jax, feeling that if he knew who his father truly was, Jax would get deeper into the club out of guilt, therefore getting him further from her . </P> <P> Tara eventually heads to a medical conference in Oregon and takes Abel and Thomas with her, most likely for an indefinite stay . Jax accompanies her and on the way there the assassins hired by Clay try to kill her . Tara survives thanks to Jax, however during the fight her right hand gets smashed in a van door . Her hand is repaired, but the nerves are terribly damaged . Her doctor affirms it is unknown if it is permanent but she feels otherwise and believes her career to be over . Jax, extremely upset himself, tries to comfort her, but Tara has become distant and asks him to leave her alone . She feels that now their future is set and they will never get out of Charming . She's later encouraged by Jax that everything will go as they had planned, which Tara barely believes . </P>
