As Kid is analyzing the patterns, Kon just stands there, quietly panicking. There doesn't appear to be any kind of floor beneath them, so do they just drop into the abyss if they get knocked off? Would the powers in charge really do that to a person?

For a moment, Kon debates just running and trying to reach the end before the pillars swing back. Nevermind that a normal human wouldn't be able to make it that distance in enough time, maybe he could! But then Kid grabs his hand and suddenly there's a plan of some sort.

"Okay," Kon says hesitantly, "But if we get knocked off, I'm blaming you."

Not that they would have much time to blame each other, if that really was a long fall into nothingness. The shock and force of the fall would render them unconscious in seconds.
