A promo for the episode shows Lydia still looking for clues in Stiles's disappearance and Liam is in trouble. Lydia tells Sheriff, "You can't just erase people They leave things behind," which cuts to a shot of Stiles' jeep, from where he was abducted by the Ghost Riders.

The promo also shows Jordan Parrish showing off his Hellhound powers, as Scott says, "Its the only way to protect them, all of them." The promo ends with scenes of Liam fighting the Ghost Riders and later is taken away by one of them.

Another promo for the episode shows Lydia's bizarre encounter, wherein her instincts are trying to tell her something. A person appears in front of her and yells out, "You didn't see it did you?!

"See what" replies a scared Lydia to which he replies, "It's right in front of your face" then Lydia starts to pull the wall sticker.

Episode 3 of season 6 revealed that Mr. Douglas –the new teacher at the high school –is the Nazi Alpha werewolf who escaped from the Dread Doctors lab in season 5 finale. The supernatural creature kills people by biting open their skulls and eating their pineal glands.

Also, Scott and Liam realized that all the students who saw the Ghost Rider at the party are now targets for the Wild Hunt. Meanwhile, Scott, Lydia and Malia track down Sheriff Stilinski's father Elias, who is also nicknamed Stiles. But it turns out he has dementia, but he seemed to remember Stiles as his grandson.
