Charisma Carpenter

Buffy the Vampire Slayer alum Charisma Carpenter has been cast in a recurring role on ABC Family’s The Lying Game, TVGuide.com has learned exclusively.

The Lying Game: Who’s who and how is it different from the books?

The series stars Alexandra Chando as separated-at-birth twins Sutton and Emma, who swap places unbeknownst to their friends and family. Carpenter will play Rebecca "Annie" Sewell, the estranged sister of Phyllis Chamberlain (Sydney Barrosse) and aunt of Sutton/Emma’s best friend, Char (Kirsten Prout). Rebecca’s return to town after many years brings back old memories — and secrets — that Alec Rybak (Adrian Padsar) and Ted Mercer (Andy Buckley) would like to keep in the past.

Carpenter, who recently appeared on an episode of Supernatural, begins her arc in the show’s midseason premiere, which is slated to air in early January.
