Sometimes you just need to hide a body. But either way, Vincent hasn't shown any malice toward the Drifters. Quite the opposite. If he's a killer of some type, he's one on their side.

Probably.

"Do whatever you want." He's not going to hold anyone to remaining loyal to their promise about such things. Not if it might be for the betterment of Levi's friends or the Convoy's Drifters.

But Vincent tilts his head. Oh? The lad could pick that up? Instead of denying it or making a plausible reason, the tall man instead offers a dry query.

"Why do you think?"

Even if Levi's world didn't have vampires, the clues should suggest the reason why.
