With production underway in Atlanta on Teen Wolf’s second season, the returning original cast is being joined by four new recurring characters who sound like a whole bundle of bad for our resident lycanthrope, Scott (Tyler Posey). First is Battlestar Galactica’s Michael Hogan, who will appear as Allison’s grandfather, a lethal werewolf hunter with plans to draw her into the family business. Stephen Lunsford (Private Practice’s Dink) will pop up as a Beacon Hills High student with a knack for photography and an eye for Scott’s girl, and Daniel Sharman, who previously tackled otherworldly roles in The Immortals and The Nine Lives of Chloe King, will play a lacrosse teammate of Scott’s, and Alpha Derek’s dangerous new pet project.

The fourth role is a still-to-be-cast mystery lady
