[When you're semi-unkillable, have poisonous blood, and have come out the other side of what should have been a successful suicide attempt, your survival instincts when faced with a vampire might just be a tad skewed, so why not ask questions? What kind of scientist would he be if he wasn't curious?]

I'm not entirely buying it, but let's table that for a second. Why are you a vampire and not just a super-fast, child of immortals, vegetarian with sharp teeth? Or is this a valid lifestyle choice for vampires like veganism for humans?
