Last season, Jax tried to pass off guns to black. He wanted to go legit and thought this would play well for everyone. Well, the Chinese and brown didn't love that. Everything still looked like SOA would get out and be good. In the last episode, Tara was still trying to get the boys out alive before they went down the SOA road. She was debating whether or not to do a deal with the Feds to protect the boys. Jax found out but realized that she was right in trying to save them. He forgave her. But, Gemma didn't get the memo. She then proceeds to kill Tara and the Sheriff who was escorting Tara. Juice walks in on this and gets Gemma out. They are the only 2 that really know what happened. She then leads SOA to believe it was the Chinese that killed Tara. This leads to an all out war between the Chinese and SOA, black and brown are also involved. Black ends up getting pissed off because SOA's fight with Chinese is without their permission and is hurting their land deals. So, black proceeds to go after finishing off Samcro because they are trying to blackmail black with information about a black preacher that is holding up one of black's land deals. They then capture Bobby and proceed to send him piece by piece to get Samcro to play ball. It ended last night with Bobby being killed and Jax being lost and confused with where he went wrong. Also, Gemma now feels very responsible for what happened and Abel is watching all of her apologies which I think leads him (he has done gone crazy kid) to kill off Gemma.
I think that is about all. And, while writing that, I realized how insane this show has become... I still love it though.
