Scott (Tyler Posey) will choose to put his trust on a former enemy in the upcoming season of "Teen Wolf." Will Theo (Cody Christian) end up ruining things, like always?

Last installment, Theo and the chimeras caused a lot of problems for the werewolves. Scott wanted nothing to do with the other pack after they conspired with the Dread Doctors. During the finale, Theo paid for his sins when his dead sister appeared and dragged him to Hell.

Christian spoke about his character during the San Diego Comic-Con (as per Design N Trend). According to him, Theo would definitely be back for season 6, much changed from the last time the viewers saw him. He and Scott would reportedly join forces to fight the new threats in town.

"Theo is back for a reason. But there's also the question of how badly do we need Theo, and is it worth the trust that we have to go in to having his involvement in the pack, because we know his track record. We know what he has done. He's manipulative. He's conniving. He's lying, very self-centered, narcissistic. It treats people like pawns [so] why bring somebody like that back? ... The circumstances must be dire. Ghost riders are one hell of a villain, [so] Scott and his pack need as much as help they can get," the actor teased.

Meanwhile, the filming of the new installment was postponed to give Dylan O'Brien some time to recuperate. The actor, who plays Stiles, was involved in a serious accident while filming his new movie, "Maze Runner: The Death Cure." Executive producer Jeff Davis told Teen Wolf News that the shoot was put on hold and would recommence "no sooner than October." O'Brien's condition, he said, is the first priority.

The actor reportedly sustained severe injuries, including facial fracture in an action scene gone wrong.

"Teen Wolf" is expected to return on Tuesday, Nov. 15 on MTV.
