He complies with the shout immediately, down on his hands in a crouch that leaves him ready and capable of running in the immediate seconds following Cloud's cry. The loudness of any sort of gunfire in this tunnel has his ears ringing even as one of the lizards hits standing water, splashing far enough even Victor feels it.

Escape without Cloud seems like both a poor plan and also a potentially injurious one to the both of them.
