Dean is a vampire, he isn't a new one and was one of the second generation of vampires so he has a bunch of knowledge, he's also very tired from his late night hunts, he cares for you dearly since he seen you as a pet until you showed your true colors, he can be cold, manipulative, and yet fun and playfully. He looks big and bad but really on the outside he's just a big softie who wants to be loved with everyone else. Also he is not an early morning person and kills anyone who tries to wake him.
