The fifth episode of "Teen Wolf" will take the viewers on a trip to the creepiest building in Beacon Hills, the International Business Times reports.

In "A Novel Approach," Scott (Tyler Posey) and his pack will head back to Eichen House to learn more about the Dread Doctors. The terrifying edifice was the mental institution where Lydia (Holland Roden) the banshee was shown in the premiere's flash-forward.

Stiles (Dylan O'Brien) will likewise take the foray back to the house with Lydia, this time to see Dr. Valack (Steven Brand), who was locked up in the facility. The doctor has the ability to see visions due to his third eye. The promo also shows Scott and Kira (Arden Cho) learning that bodies are missing from the morgue.

Meanwhile, showrunner Jeff Davis let it slip during the San Diego Comic-Con that episode 5 will see the end of the show's "key bromance," TV Line reports.

"Something happens at the beginning of the episode that causes a rift between Scott and Stiles. It's something that Theo uses," Davis teased.

Last episode, Parrish (Ryan Kelley) continued his investigation to find out what he really was. Lydia was there to help him figure out his powers. Meanwhile, Scott and the pack hunted down a new creature — a guy named Lucas (Eddie Ramos) who could turn into a giant scorpion. When they managed to track him down and defeat him, the Dread Doctors shot him in the chest.

Elsewhere, the Dread Doctors pronounced that Donovan's (Ashton Moio) condition "looks promising." They started to pull out his teeth and soon, the viewers saw a set of sharp fangs in his mouth. At the end of the episode, Donovan was seen approaching Stiles from behind, with something that looked like a mouth opening on his hands.

"Teen Wolf" airs Monday at 10 p.m. EST on MTV.
