Jesper sees one person eyeing Nadine, perhaps thinking of trying something in response, Jesper simply slices a blade toward him and he doesn't manage to make a sound before it lodges into his throat. Quick, easy. Maybe he would be too afraid, but best to use scare tactics right away. None of them are going to survive at this point, as far as he's concerned.

"See that? That was stupid," Jesper drawls. He's backing up Sam's statement, even if to them maybe the dead man didn't seem like he was trying anything. Just as a warning. Anything can be stupid right then.

Jesper calls the bullets back to him so he can reform them properly to be used again. It's fairly easy for him, that's why he almost never needs to actually refill his ammo. The blades remain hanging in the air as a warning to the others, since it seemed so very easy. He nods to Dean to get them started on what they're looking for.
