“A Novel Approach” gives us some outstanding acting by Dylan O’Brien. He is a shooting star and a huge part of what makes Teen Wolf so great. Jeff Davis had warned that an event in Episode 5 would create a rift between Stiles and Scott, but we didn’t expect it would be muuurder! Teen Wolf lets its supernatural flag fly with a visit to the special basement wing of Eichen House and an explosion of kitsune power. Eichen House reminds us of the bleak future of our pack, particularly when Lydia is eyeballed by the creepy needle-obsessed attendant we last saw in “Creatures of the Night.” In “A Novel Approach,” Teen Wolf takes us by the hand and starts leading us down the path to this unhappy future.
