In the upcoming episode which features a 'Buffy' reunion, Sam and Dean have to stop a witch who unleashes her wrath on a small town after her husband cheated on her.
A domestic issue turns into a killing spree in the next "Supernatural". A witch named Maggie Stark unleashes her wrath on a small town which results in numerous deaths, and it surely attracts Sam and Dean's attention that they investigate the case.
The Winchester brothers track down Maggie's husband Donald with hope that he can help, but Don tells them that Maggie is mad at him for having an affair and is taking it out on the townspeople. Thus, Don's effort to tell his wife that it's enough receives no good response.
Guest starring as Maggie and Donald are Charisma Carpenter and James Marsters who once co-starred on "Buffy the Vampire Slayer". Titled "Shut Up, Dr. Phil", it will air Friday, October 21 at 9/8c on The CW.
