Gabriel is a demon/angel halfling. As such he is stronger than most of the full bloods. He's sarcastic and very difficult to warm up to due to the fact that he hardly trusts anyone. Originally the plan was just to fake a relationship with Serena to piss off her dad, but then feelings had to get in the way, and complicate things. 

*I would like his voice to be a nice middle ground of a deep voice and a slightly higher voice*
