Gearing up for its seventh and final season, "Sons of Anarchy" fictional town of Charming is going to welcome a new female sheriff that will investigate the death of Sheriff Rossevelt and Jax's wife, Tara Knowles. Still struggling to make a decision, Juice (Theo Rossi) is in a difficult position where he could rat Gemma (Katey Sagal) out to Jax (Charlie Hunnam), as he helped her dispose of all the evidence related to Tara's murder.

Still mourning for SAMCRO's queen, Wayne Unser's (Dayton Callie) misinformation is the reason why Gemma put a meat fork on Tara's head and now he is helping the police, with the murder investigation. With the body-count piling up, series creator Kurt Sutter revealed recently that there are two club members who are not going to make it to the final ride.

Returning for a darker season, "Sons of Anarchy" season 7 is fuelled by vengeance and Jax is going all the way to avenge the death his wife, with MC supporting him. Expected to pick up 10 days after Tara's tragic death, the show's premiere is set to show that Dr. Knowles' death is affecting everyone, especially Gemma, Unser and Juice.

"Although Wayne isn't exactly privy to how his words led to Tara's doom, he's mourning the loss," TV Guide reports. "So much so, in fact, that he even finds a way to help the new sheriff with the murder investigation. Although it's great to see Unser flexing some of his old lawman muscle, there's at least a couple people who certainly don't want Unser digging around. In other words, he better watch his back."

Juice is becoming one of the most dangerous characters in the show. He is completely in a different position and this time he is going to use his much feared secret as an an advantage. Linked to Gemma for the show's biggest cover-up, he is currently in hiding for Sheriff Roosevelt's murder but will soon take some drastic steps to keep his secret.

""What she's done and what she's hiding, there's only one other person who knows. At that moment, Juice becomes one of the most dangerous people on the show," Revealed Rossi said in an interview to TV Guide.

The final season will also feature rock stars Marilyn Manson and Courtney Love, and "Glee" star Lea Michelle. "Sons of Anarchy" season 7 is scheduled to premiere on Sept. 9 on Fax.
