At least that won't be too much of a problem as Donnie's battle shell kicks in again, and he flies them full-speed for the other end of the room.

Leo can see the last of the tiles below them seal off the heat as they reach the doorway, but Donnie doesn't stop until they're through- a good call, it seems, given that not long after the floor completes itself, the door hisses shut behind them.

Slowly, hesitantly, Donnie brings them to a halt, gradually setting back down on the floor as he looks back at the door. His heart's hammering in his chest, arms still tight around Leo as he tries to catch his breath.
