charisma carpenter james marsters 'Supernatural' Season 7 reunites 'Buffy' stars Charisma Carpenter and James MarstersThat sound you just heard was every nerd on earth falling over after going catatonic with sheer elation.

We’re still brushing ourselves off.

“Supernatural” welcomes Joss Whedon alum Jewel Staite as a guest star in its third episode of Season 7, and E.P. Sera Gamble isn’t stopping there. “Buffy The Vampire Slayer” star Charisma Carpenter revealed on her Twitter that she’d be guest starring in a “Supernatural” episode this season.

Now, TVLine confirms that it gets better. She’ll reunite with her “Buffy” co-star James Marsters in an upcoming episode that films August 22.

The episode, entitled “Shut Up, Dr. Phil,” features Carpenter and Marsters as a married couple on the outs. She’s a witch, so when they were happily married, their life was terrific — but when he falls out of favor with her, his luck changes, big time. Gamble describes the episode as “‘Bewitched’ gone wrong.”

Cordelia and Spike, married. Thoughts? Is it just enough, or do you worry that the stunt casting may take away from the story? Weigh in below.
