'Teen Wolf' Alert: Get Ready To Meet Even More Members Of The Argent Family

Find out who'll be appearing on the MTV series!

Marie-Jeanne Valet (played by Crystal Reed *squeal*) isn't the only Argent ancestor we're about to meet. No-sir-ee.

Gilles Marini ("Sex and the City," "Dancing With the Stars," "Switched at Birth") and Lachlan Buchanan ("The Young and the Restless") will guest star in the highly anticipated February 23rd flashback episode of "Teen Wolf," according to TVLine.

Marini will play Sebastien Argent, a French soldier who comes home to the countryside of Gévaudan only to find out that a trecherous beast — shocker! — has been bludgeoning his nearest and dearest, including his younger sister. The best part? Marini is eerily familiar with La Bête, which actually did exist in the 1700s!

“[Gilles] was excited to do the story,” executive producer Jeff Davis told the website. “He’s French, and for his family, the Beast of Gévaudan was their Boogeyman. They would all tell stories about the Beast, so it was a very familiar character to him.”

Meanwhile, Buchanan has taken on the role of Henri Argent, a hermit who lives alone in a forest grove of sorts. Henri is no stranger to the supernatural (typical Argent) and is described by Davis as "wise but guarded."
