"I can," Childermass answers. The simple part is ordering the constructs to move on ahead again, to look around, though he can't quite check in through them with Lambert's next request.

"The fog, though... Let me see what I can do." With him focusing his magic elsewhere, the shadows are more or less moot, even if they do scurry on further in. Back where they're all actually standing, Childermass will step to the front of the group and hold a hand out in front of him, summoning up a firm wind from behind them, trying to force it into the form of a wall that he can continuously keep ahead of them to dam up the fog and push it away.
