It occurs to Viktor that without a visual, he could be hearing things. This place could be playing tricks on him, an effort to drag him deeper into the illusion--but for what purpose? There's a great deal about this that makes little sense. Perhaps the simplest solution is also the correct one, and Jayce really is here, on the other side of the wall.

"I'm unhurt." Which is not necessarily okay, but it's a start. He shifts against the wall, turning slightly with the hope that his voice will carry better. Some part of him knows he should actually get up--try and find the path that leads one row over, but he can't quite will his body to do so.

"Do you see another way around? I'm not certain I can get to you."
