Will Jax ever find out that his mother is the one responsible for killing Tara? That seems to be the question for every “Sons of Anarchy” fan for the seventh and final season of the hit FX series, which premieres Sept. 9. And according to TV Guide, the chances of Jax realizing the cold, hard truth are pretty high considering Gemma’s dirty little secret will be exposed during Season 7.

The final season of “SoA” will kick off with Jax behind bars just 10 days after Tara’s death. But if you think for a moment that hard time will be beneficial for our protagonist, guess again. Instead of using his prison time to grieve, Jax will spend his days plotting revenge.

According to reports, Jax will return to Charming with guns a-blazin’, attempting to find out who killed his wife. But Gemma will immediately intercept her son with wide open arms, pointing him in the complete opposite direction.

TV Guide revealed that Katey Sagal’s character will try to pin off Tara’s murder on a rival gang and unfortunately Jax will take the bait – hook, line and sinker. Because of this, a “war” will break out between the gangs and rumor has it it’s going to be a bloody battle.

As Jax dukes it out with those wrongly accused, Gemma will use her free time to keep Juice out of sight. The last time we saw Theo Rossi’s character, he wasn’t on the best terms with anyone in SAMCRO – especially Jax. But Gemma’s efforts to keep Juice concealed will be disrupted when the duo’s deadly secret gets discovered by an “unlikely source.”

This raises a lot of questions like: Will this mysterious source use Gemma’s dirty doings for blackmail? Or will the source immediately go to Jax with the information they found? We're also wondering how did they find out that Gemma killed Tara and Juice murdered Sheriff Roosevelt?

"Sons of Anarchy" returns Tuesday, Sept. 9, at 10 p.m. EDT. Who do you think the “unlikely source” could be? Sound off in the comments section below with your theories. We’d love to hear them!
