Teen Wolf may be heading back to Eichen House during season 5.

'Teen Wolf' Season 5 Spoilers: Derek To Appear? Linden Ashby Teases Tyler Hoechlin's Brief Return

The MTV drama was spotted filming at Mary Andrews Clark Memorial Home in late March, according to Teen Wolf News, a spot that has served as Beacon Hills' notorious insane asylum in the past. Eichen House served as an integral (and highly frightening) location during the last two seasons and it may soon become the feeding ground of a Sluagh.

The Sluagh is the result of Teen Wolf's competition for fan created monsters. Designed by Jessica Short of Brooklyn, the creature will also be played by a fan - 16-year-old Make-A-Wish participant Michael Lynch. It appears the Texas native will spend time stealing souls from his peacefully sleeping victims and replacing them with tainted ones.

An Eichen House return comes as little surprise after the season 5 finale revealed that the asylum had a special section for those afflicted by supernatural ailments. The power-mad Peter Hale (Ian Bohen) is currently occupying a room in this locked ward (see why in the video below).

"We just loved the idea of having this lower level of Eichen House," series creator Jeff Davis teased, according to Entertainment Weekly. "We know Eichen House isn't the greatest place in the world, but what if they had a wing, a sub-level where they kept people like that?"

Hopefully we'll get to see Beacon Hills' very own "Arkham Asylum" used during season 5.
