Most of the hounds are buffeted back by the Soldier's metal arm, but one does manage to get around to the other side— only to be stabbed in the forehead by the knife.

It yelps and staggers back, then collapses.

The others redouble their assault, one trying to latch onto the metal arm (and not really succeeding) and two going for the Soldier's legs.

The green-eyed beast, meanwhile, ducks to the side while another hound steps out in front of it to take the dagger in the shoulder. It takes the flame as well, though the heat doesn't seem to affect it much. Almost immediately after, the green-eyed hound opens its mouth wide, and wider still, and from deep within the gaping maw shoots a jet of water, straight at Crowley.

Water that, if any of it touches him, will burn like it's been blessed.
