Childermass slides back a step, watching Strange remove the water without much need for commentary. When he turns back to agree with his own conclusion, just one more blast, he nods and looks back down at the Growlithe. The dog's been watching the two since they came up, tail wagging briefly when Childermass glances down again.

"Once more. Flamethrower," he tells him, waving down into the hole.

That's all the Growlithe needs, hopping back to it with a second intake of breath, followed by yet another stream of fire blasting from his jaws and down into the frozen pit.
