First Look: Buffy vets Charisma Carpenter, James Marsters Guest Star on Supernatural

James Marsters, Charisma Carpenter It's a reunion so epic there must be Supernatural forces at work! Ex-Buffy costars James Marsters and Charisma Carpenter team up on the October 21 episode of The CW shocker to wreak havoc on the Winchester boys as a pair of marrieds with issues far more wicked than anything their former characters Spike and Cordelia ever encountered. "Charisma plays a very powerful witch," says executive producer Sera Gamble. "In the episode, she starts throwing her power around because she and her husband are in the middle of a contentious divorce." Where's a good vampire slayer when you need one?
