On Teen Wolf Season 6 Episode 5, Stiles finds himself in a train station where no one seems to be able to remember how long they've been there or what train they are getting on. Then, the Ghost Riders show up, dragging another victim in. To make matters worse, Stiles runs into Peter.
Stiles and Peter try to figure out how to get out of the train station. Well, Stiles does, and Peter tags along, telling Stiles that they can't get out because there isn't a train station in Beacon Hills.
They manage to find a guy who has been trying to escape as well. Basically, everyone in the train station is comatose, essentially, except for Stiles, Peter, and this random guy. The guy tells them that the only way out is to hop on the back of the Ghost Riders as they are riding out through a portal. The guy tries, and it does not end well for him. RIP random dude.
Back in Beacon Hills, Lydia, Malia, and Scott discover Stiles' jeep, Roscoe, in the school parking lot. Scott picks up all three of their scents in the jeep. Also, the weirdest thing happens where the radio turns on and starts broadcasting static. Of course, unbeknownst to the pack, this is due to Stiles tinkering with the intercom system in the train station.
Back in the train station, Peter figures out what the board reveals, and it urges him to hop on the back of the Ghost Riders and go through the portal. He tells Stiles that the Ghost Riders are going to take everyone in Beacon Hills.
Peter survives going through the portal, barely. He is badly burned and in a lot of pain. Malia and Scott recognize him, and Peter gives Malia the keys to Roscoe.
Once Lydia and Scott get the jeep running, the radio comes back on. It's Stiles. They remember him, and he tells them to find Canaan.
