For a moment she just stared at Buffy, unmoving, eyes wide. Kara had a very fast mind, that processed information much faster than humans. But what Buffy had just said had confused her even for a second.
"Dracula." she repeated, finally blinking, and then tilted her head. "As in...guy from the legends, books, and really cheesy movies?" he actually existed? "Seriously?" wow. Maybe she needed to give more credit to the movies.
So if vampires were stealing abilities from someone she thought was just a myth, what was the plan? "So you're going to what? Track down Dracula and...ask him what's up?" would Dracula even help them, or would this be more of a forceful thing. Not that you could be forceful with someone who didn't die.
