Crowley sees the creature leap at him and immediately ducks. Right, there are better things he could do right now, more cohesive things he can do, but this thing can spit holy water----

Wait, the holy water. He looks down at his arm, which stings but isn't melted off. What the hell happened there? He should be dead right now. Dead as he was when he originally died. That should've been it, it should've been all over. How did that----

He sees the human soldier person leap into the fray and decides now is not the time to think about it. He grips the leash again and pulls downwards, to see if he can get the creature off-footing.
