Iiiii know nothing about TVD so I can't really comment there.

BUT BRENNAN! She is great! I really enjoy bouncing Jason off of her. Their conversations are always entertaining, especially considering how different they are. I love that you aren't afraid to put her out of her element. Not only do you do that and do it well, but you have her react like a normal person would and not just throw things in there for the sake of random.
