The seventh and final season of "Sons of Anarchy" keeps heating up episode-by-episode. In Episode 4, entitled "Poor Little Lambs," Lin discovered the guys who destroyed his business. Lin knew it was Jax and his crew, and he wasn't very happy about the betrayal.

Well, there weren't any lambs slaughtered in "Poor Little Lambs" except for the girls working in the massage parlor. But when it comes to the major characters, no one has gone down yet like fans expected. At the end of the episode, one of the Triad club members threw a grenade into the massage parlor hoping to kill Jax and his crew, but it was unsuccessful.  Jax and his crew survived.

In episode 5, entitled "Some Strange Eruption," the war between Jax and Lin continues on. Jax and the rest of SAMCRO will try to find out who betrayed them and spilled the beans to Lin. The summary for the episode says something about "violence at the Stockton Ports," which could be some really bloody encounter between the opposing sides.  It reads: "Looking for the source of a betrayal leads to violence at the Stockton Ports.

In the Episode 5 promo, it appears like there's a gunfight between the SAMCRO and Triad.

Jax tells Lin, "You're going to watch as my guys rip apart your crew."

Additionally, Jax will also tell Nero that it was Gemma who told him that Lin's crew murdered Tara, according to IBT.

And what about Gemma's secret? Jax is getting closer and closer to the truth. Unser confronts Gemma and wants her to reveal who she saw kill Tara. It looks like more and more people are digging for the truth about Tara's murder, and this puts Gemma in a very dangerous situation.

"Sons of Anarchy" Season 7 Episode 5 will air on Oct. 7 on FX.
