A promo for this Tuesday's episode shows Stiles trying to befriend Peter Hale to find a way to break out of the Ghost's Riders' prison. Stiles asks, "There is got to be a way out of this place?" But Peter is pessimistic about their chances of getting out and replies, "If this is the Wild Hunt, there is no escape. You and I are doomed to ride this storm forever," as we see many Ghost Riders bringing more children to their hide-out.

Peter insists, "We are already forgotten!" But a hopeful Stiles says, "Somebody is going to remember me. Lydia, Scott, Malia... They will come for me."

Another preview for the episode shows a discussion between Stiles and Peter about their disappearance. They are both abducted by the Ghost Riders and are currently being kept at an old train station. Peter asks, "How long have I been here?" Stiles tells him it's been three months. "I have been missing for 3 months and no-one came for me?" Peter asks.

Then Stiles explains, "That's what the Ghost Riders do. They erase you." Later Peter explains that Ghost Riders "ride the lightning, they are an unstoppable force and I promise you they don't make pit stops at train stations."

Previously, Teen Wolf showrunner Jeff Davis spoke about Peter (played by Ian Bohen) at the New York Comic-con. He said, "When we realized this might be the last season, we wanted to make sure we brought back these relationships. We definitely wanted Peter Hale back to see the relationship between Peter and Malia and what other trouble Peter could get into... and we also have some great scenes between Peter and Stiles. I wanted to see again and Ian and Dylan [O'Brien] have some great stuff this season so we'll see."
