Teen Wolf: Season 5B – Gilles Marini & Lachlan Buchanan to Guest

Prepare to meet a few more people from the Argent family’s (very distant) past.

Gilles Marini (Switched at Birth) and Lachlan Buchanan (The Young and the Restless) will guest-star in Teen Wolf‘s Feb. 23 flashback episode, TVLine has learned exclusively.

Marini will play Sebastien, a French soldier who returns home to the countryside of Gévaudan, only to discover that a vicious beast — I’ll give you one guess which beast it is! — has been terrorizing the people he loves, including his younger sister.

Buchanan, meanwhile, will play Henri, a recluse from the Argent family line who lives alone in a forest grove. Described as “wise but guarded,” he knows quite a bit about the supernatural world (as any good Argent should).
