Welcome to the house of whacks! Sam (Jared Padalecki) and Dean (Jensen Ackles) will pay a visit to a creepy bed and breakfast in episode 5 of “Supernatural” -- one that used to belong to an iconic killer: Lizzie Borden.

Borden was tried and acquitted for the murders of her father and stepmother, Andrew and Abby Borden, in Fall River, Massachusetts, in 1892. The two died after receiving crushing -- and repeated -- blows to their heads. (The disfigured skulls were used as evidence during Borden’s trial, which she reportedly fainted at the sight of.) Although Borden was never charged with the gruesome deaths of her parents, many speculate that she is responsible for their demise.

“Sam and Dean investigate a series of murders at a local B&B that also happens to be Lizzie Borden’s old home,” the Season 11 synopsis explains. (But the summary doesn’t reveal why anyone in their right mind would enjoy a breakfast buffet in the home where two people were slaughtered. Gross.)

“It’s a tourist trap,” Dean says after getting intel on their next paranormal case. And what a trap it is! In the promo video for episode 5, titled “Thin Lizzie,” audiences watch as an excited, gore-loving girl asks her significant other whether or not they’ll see anything spooky during their stay at the bed and breakfast museum.

But it looks like she never does witness any creepy occurrences because moments later she gets stabbed in the back -- literally -- by a mysterious killer sporting a dark cloak.

So who is behind all the killings at this eerie B&B? Well, when a local man tells the Winchester brothers that he spotted a little girl wandering around the haunted museum near the time of the murders, Sam and Dean will theorize that Amara may be responsible for the grim killings -- and for good reason! This sounds like something that would be right up The Darkness’ soul-sucking alley.

“Supernatural” airs Wednesdays at 9 p.m. EST on the CW.
