Warning. This is psycho dark and disturbing.

Having said that, Derek's love might be pathological but it is no less real or intense or absolutely vital to his being because of it. Kudos to him. He's a master manipulator and quite the charmer with infinite patience and impressive control (when he puts his mind to it).

I admit I was shocked and devastated at a crucial point in the story but …. *shakes head* just as entranced and under Derek's powerful spell - just like Stiles, who is in absolute awe and trapped when he doesn't even know he's caught.
