Buffy/Angel alumni James Marsters and Charisma Carpenter are set to conjure up some intense marital strife when they guest-star on The CW’s Supernatural this Friday — and TVLine has an exclusive clip from the genre-gasmic episode.

In “Shut Up, Dr. Phil,” Carpenter plays Maggie, a real w-i-t-c-h who is extremely toil-and-troubled by an indiscrection of her husband Don’s. To that end, she’s been acting out a bit with her sorcery skills. As Don points out in this scene, the far-out goings-on have not gone unnoticed by a certain pair of “FBI agents.”

“Hunters, sweetheart,” Carpenter’s sexy spellcaster corrects her spouse. “That’s what they are.”

Sam and Dean had better hurry up said hunt, because based on how this art gallery confrontation ends, Maggie’s witchy worst is yet to come!
