You're not, I promise. I just have this thing about me from being The Slayer that I can shift when someone may not be human. You didn't ping on my "Bad, dangerous, radar and I understood why you were keeping it to yourself.
We're friends and I'd never expose you like that. And anyone who wants a go at you has to go through me.
Now, would having blood help you heal faster? I can't feed everyone that might be a vampire, but I feel I can trust you so I can be your donor from time to time.
