Whew! Teen Wolf has been busy! Filming for Season 3 starts soon, which is why they need a whole new set of werewolves.
At the end of Season 2, Derek (Tyler Hoechlin) told Scott (Tyler Posey) that a new alpha pack was in town, and they probably didn’t want to play nice. Zap2It reports that Gideon Emery (Last Resort) will lead the newcomers as Deucalion. In addition to an epic name, Deucalion has "an eloquent, cutting intelligence," which he’ll use to get Derek and Scott at each others’ throats.
In Greek mythology, Deucalion was the son of Prometheus. We’re pretty sure this pack leader is going to set Beacon Hills ablaze.
