Age: Well...if he hadn't turned into a vampire at the age of 22, he'd be 25 right now.
Orientation: Well, with him trying to keep a tight hold on his humanity, he tries to fight off everything to do with what vampires are. Including Bi. But given the right sort of incentive, he'd probably realize his true sexual orientation.
Good or Evil?: Good
Orientation: Unknown. He's very impressionable y'see.
Good or Evil?: Again, he's innocent and doesn't really know right from wrong.
