Clever boy. Only after a short pause does Vincent ask Levi,

"Why would I need to hide the bodies of monsters I kill?" It's an excellent counter. Shouldn't there be no reason to suspect Vincent is somehow not doing this for the practical reasons he addressed earlier?

Still, the gunman takes a pace or two closer to Levi as he speaks. There's probably no danger. There doesn't seem to be any malice or rising sense of threat.
