The Ghost Riders continue to terrorize the residents of Beacon Hill in last night's episode of "Teen Wolf". The latest installment sees Scott (Tyler Posey) determined to protect everyone, especially his friends, who are now in danger of being taken.

Last week, Scott told Liam (Dylan Sprayberry) and his other friends to find a place to hide Gwen (Alisha Boe), and Mason (Khylin Rhambo) had the brilliant idea of having Scott host the lacrosse party at his house and hiding Gwen there for them to be able to keep an eye on her. Everything was going well until a Ghost Rider appeared and started chasing a terrified Gwen down the stairs. Though no one could see the Ghost Rider, Corey (Michael Johnston) made a mistake by grabbing it, rendering the villain visible to everyone at the party. Mason was able to save Gwen, but now that everyone has seen one of the Ghost Riders, they are more likely to be taken by the posse.

In a sneak peek at the episode titled “Relics” posted by MTV, the boys are staring at a strange marking on the ceiling, wondering how the Ghost Rider was able to infiltrate Scott’s house. Mason says that the mark is a point of impact left by the lightning strike and that people usually find spots like that on the ground after a violent thunderstorm. At that point, Scott realizes how the Ghost Rider got in.

“He rode the lightning,” the wolf pack leader says, adding that if that’s how the Ghost Riders get in, then no place in Beacon Hill is safe. Corey blames himself for endangering everyone at the party, saying that those who saw the Ghost Rider is now marked and is about to be taken.

“We’ll find a way to protect them,” Scott vows. “All of them.”

Elsewhere in the episode, the search for Stiles (Dylan O’Brien) continues according to TVGuide’s official description of episode 4. During the hour, Lydia (Holland Roden) discovers clues about what happened to the love of her life.

“Teen Wolf” airs Tuesdays at 9 p.m. on MTV.
