I am half vampire by my father. This means, of course, that I drink blood, though I will never take from an unwilling partner. The closest method I have to a blood test at this time is to perform a single finger prick and to taste in order to determine your state of health.

I ask for your permission to do this. I will not if you do not agree to it, Rogue.
