Executive producer Jeff Davis spilled to TV Guide, "The idea behind Scott's wolf look was to retain as much of his humanity as possible. [...] His look will progress the more he's able to control his powers. The most powerful werewolves in our mythology are the ones who can go beyond transforming into a monstrous-looking hybrid like the Alpha and can actually shift all the way into a normal-looking wolf. The ability to blend seamlessly into nature is what makes them particularly dangerous."
Unless Scott manages to dig up a cure in Season 2, expect a little less mountain man and a little more beast as the too-cute teen learns to harness his supernatural powers.
