Angel
Love makes everyone a little bit crazy. Would I be correct in guessing you dated her first and when you had a soul and he didn't? He strikes me as a man who obsesses, clings, or in kinder terms is completely devoted to a goal, a person. Why can you not be with her right now?
Listening to yours takes the weight off mine, if for a few moments. You are kind enough to offer me protection for nothing in return. But to return not even some friendship would be a gross indecency on my part. And I would like to be your friend.
Not much kills vampires in my world: sunlight, stakes in the heart, sometimes fire. And the werewolf bite, though it's almost a legend for how few werewolves there are. You've traveled through dimensions before? Magic can fix the sunlight problem in my world, if you know a witch who likes you.
No, it is not. I became a vampire when he chased me. Someone I thought would help me turned on me, so I tried to kill myself, rather than be returned to him. She didn't let me do so, but I became a vampire, no longer of any use to him, except to torture and hurt. He slaughtered my entire family for doing so. [...] But Angel, though the rest from my world will learn of it when they come near my person, you must not tell anyone... I'm human again.
Thank you. I would like to keep living, so that I may someday gain something I've lost.
He has the potential, but Sherlock Holmes is not, in the stories I've read, a white knight who defends all the innocent people. I won't lose everything by trusting him too readily.
