In addition to the time jump and the surprise return of Crystal Reed as Allison Argent, 'Teen Wolf: The Movie' has another significant change: Scott's best friend Stiles (Dylan O'Brien) is nowhere to be seen.
A slew of the original show s stars are reprising their roles for the film including leading man Tyler Posey, back in the saddle as the now-adult werewolf Scott McCall gathering his old allies.
