Zaknafein, for what it's worth, is trying his best to understand. The main problem being that for signing of any sort to work, one needs to actually be able to see what the other is doing to make sense of it. He picks up on the vague gesturing, but while he figures that the gesturing has to do with the light, he has no idea why the wizard is point to the wall. He cannot see the switch, nor does he know that it is even there.
He tries for a moment to look back in the direction he'd come, but snaps his attention back to Caesar almost immediately. He cannot hear the footfalls or voices of his pursuers, but there is an ever present hum in the air that he doesn't recognize. The Underdark can be so very silent at times, that even the hum of modern electricity can sound deafening to one unaccustomed.
Should Caesar try to move, Zaknafein will take a step in the opposite direction, keeping the distance, and the sword blade, between them.
It's like using sign language with a blind person right now
