And so Childermass will do just that, crouching down and pulling up a few shadow constructs — rats this time — up out of his own shadow. No words needed, only a nod of his head in the direction he wants them to go and they go scuttling off. Once he's standing again and they're out of sight, he'll put one hand back on Lambert's shoulder and close his eyes.

Since he's going to be projecting his senses to the constructs, he'll need someone to keep him from tripping and landing face first in the tunnel dirt if they start walking again.
