Teen Wolf season three promises to gift present fans with an episode set in the past, and ETonline has exclusively learned that actress Ana Walczak is set to make her TV debut as Laura Hale, Derek's sister, in episode 8!
Laura, Derek's older sister, is a beta werewolf with the potential to become an alpha.
That hour will spend a good chunk of time examining Derek's teen years, as Ian Nelson was previously cast to play young Derek and Alicia Coppola revealed on Twitter that she would be playing Talia, Derek's mother.
So let the countdown to the June 3 season three premiere continue -- and check back with ETonline next week for another Teen Wolf morsel to sink your teeth into!
