[Huh? It's Willow's turn to be puzzled. She's not sure what could possibly be more dangerous about Ozpin than being a vampire. It's probably not the important thing to focus on right now, though.]

You say that now... Look, just be careful, okay? There was a - a good vampire at home that went bad, and uh, he started targeting the people who were closest to the one person he loved most. I'm not saying Ozpin's going to do the same, but he's drinking blood - that's going to lead nowhere good real fast.
