He came to a stop before the sheer drop, his eyes narrowing at the darker ice beneath. A fall that far wouldn't kill him, most likely, but it would hurt, maybe even keep him down for a few hours in the cold. He slowed, watching the other climb down. Peering over the edge, he watched him alter the wall of ice, molding it like one would clay or dough, forming footholds and outcrops.

His eyes were locked onto the movement itself that it took him a moment to realize what he was doing. It was a gesture for his sake.

He was silent for a while, staring between his face and his hand. "That's a nice trick." he grumbled. He didn't want to say how he wasn't sure he could climb in this state. Instead, he took his hand, his warm skin against the other's pale palm.
