Derek, Scott and Isaac hunt after Boyd and Cora. Stiles helps Lydia who found another dead body.
No Sterek but a mirroring moment. Derek meets Jennifer. She stares at him like Stiles did in 1/1. Derek saves Jennifer from the werewolves like he saved Stiles in 2/2.
Derek is more successful in glaring Isaac down than he is with making Stiles submit to him.
Stiles about the killings: "It´s not very werewolfi."
Derek wears the same khaki shirt as in 3x2 (which is shredded at the end). Stiles wears a grey plaid hoodie above a light blue shirt and red pants. Jennifer wears green.
Stiles quotes The Shining.
