IT'S VERY WORRISOME. He's aware that Methuselah can be more or less out of control if they're in a bloodlust--in his canon he almost killed himself once rather than eat Esther, because he was so low on blood he didn't think he could fight it long. So. You know. This is a very troubling possibility.

And some of the vampires in camp don't seem all that honorable. He's probably going to be telling people to avoid him soon, because he wouldn't be able to deal well with hurting his few friends.

How bad does Zero expect things to get?
