Something about being told 'thank you' makes Kon feel warm and fuzzy inside. It wasn't something he was expecting (for reasons unknown, at least until he gets his memories back), so getting recognition feels nice.

He smiles back at Kid, once they reach the door on the other side of the room. "Hey, it's no problem. We're supposed to help each other, right?"

And Kid will get the chance to repay the favor soon enough, because the next room consists of a long, narrow path spread over a huge gap. Balance itself isn't a problem for Kon, but there's swinging pillars that go flying over the path every now and then. They appear to be random to Kon, but that's because he's too impatient to notice any pattern to their swinging.

"How the hell are we supposed to do this?!"
