"I can't speak for the 'other guy' because your bite scars don't give me much to go on, but I need to consume human blood. I'm a Dhampir." D wasn't certain yet how being a Sleeper, or feeding on another Sleeper, would influence that, but he had enough dried blood capsules to keep himself fine for a while.

He could offer some theories about what the other person to bite Luke's neck might be, but there was so much here that was entirely new to D.
