Donnie'd gone down stairs by illy-suited means before. The result was very much as jarring and painful, but the fresh panic was helping to get his heart and blood pumping, and by the end of it he was clinging onto Tony with a shudder.

There wasn't any argument from him as he found himself being practically swaddled by Tony's sweater, relishing whatever residual warmth it provided. He'd be more concerned about the human's own warmth once his own brain was fully awake. Actual arm mobility was probably ideal but Donnie wasn't in any particular hurry in finding where to stick his hands to find the armholes, although something at the back of his mind nagged him that he should probably do that sooner than later.
