“Teen Wolf” fans at San Diego Comic-Con were treated to a new trailer for the second half of Season 4 Thursday. The trailer starts off very ominously. “They’re coming for us. They’re going to burn us to the ground,” a creepy voice on a cassette tape says.

The SDCC 2014 promo shows the group getting ready to fight back against whoever the Benefactor is.

“Why would someone use all this money just to kill us?” Scott asks.

Derek takes an eye-for-an-eye approach. He wants to make his own hit list for the assassins trying to kill them all. "Anyone who thinks they can hunt and kill us for money, they got to be a name on our dead pool," he says.

The trailer shows plenty of action sequences. In between, viewers see comforting moments with all the "Teen Wolf" couples: Scott and Kira, Stiles and Malia, Derek and Braeden, and even Stiles and Lydia (maybe there’s still hope for those two).

Lydia says, “Not all monsters do monstrous things.”

Of course, Peter challenges that statement. In werewolf form, he tells Scott, “It was my bite that changed your life and my bite that can end it.”

Meanwhile, Derek’s still losing his powers, and he wants to go after Kate even though he doesn’t have the power to fight her. The trailer ends with Braeden hovering over him and calling his name, making it appear as if he’s dead.
