Charisma Carpenter will be guest starring in the much-anticipated episode ‘Shut Up, Dr Phil’ tonight! In an interview with TV Line, the actress discusses her character and her on-screen reunion with former Buffy and Angel co-star James Marsters.

On working with James Marsters again, Carpenter tells TV Line,

It’s great to see my old friend! It was just catch-up [like], ‘Have you heard my song? And this is my kid.’

She also discusses her character Maggie’s relationship with James Marsters’ character, her on-screen husband, who Maggie finds out has been cheating on her:

I think we can all relate to somebody cheating on us at some point in time in our relationships and how that feels, and how irrational you become,. You’re so mad and angry, you forget… what brought you together. [And] the only way to get through what we’re going through is to just get back to the love.

Working with Jensen Ackles and Jared Padalecki was really fun, Charisma muses:

[They] were really funny. They did some really great work – Jensen with the bees and pretending to do the psychobabble on me. It was hard to keep a straight face sometimes.

And finally, on whether Maggie or Cordelia would win in a fight, Charisma says:

Maggie! Maggie’s meaner. Maggie could take Cordy out.

Aww. But Cordy might win in a contest of wits! We can’t wait for tonight’s episode.
