teen wolf shelley hennig the secret circle gi 'Teen Wolf': 'The Secret Circle' star Shelley Hennig cast in a secret role

“Teen Wolf” has made a very secretive bit of casting: Shelley Hennig (“The Secret Circle”) has been signed to play an unknown role when the show returns with new Season 3 episodes this winter.

Although E!Online was able to report the news of Hennig’s casting, nothing else is known about the role. There is a good chance that Hennig’s arrival has something to do with a new piece of mythology on the show — such changes have been teased since the San Diego Comic-Con in July. The casting of another guest star, Arden Cho, is directly tied to a “kitsune” myth. While Cho’s role of Kira may not be a kitsune herself, the character has something to do with the Japanese, shape-shifting creature.

On “The Secret Circle,” a supernatural-themed show that ran for one season on The CW, Hennig played the role of Diana. The resident “nice girl” of the group of witches, Diana also ran the teen coven. Since the show’s cancellation, Hennig has had roles on “Justified” and “Zach Stone Is Gonna Be Famous.”

In addition to the remaining episodes of “Teen Wolf” Season 3, MTV has renewed the series for a 12-episode Season 4 airing at some point later in 2014.
