Sasuke didn't notice he was shivering until the sudden warmth caused a big one to break over his body, his hands automatically closing over one another for warmth for a second. They were clean already: blood had washed away quickly in the cold water. His face, too, felt clean when he swept his hands over it one last time.

There was nothing to be done about his clothing except hope that any shinobi with a strong sense of smell wouldn't identify it as a point of concern.

Part of him wanted to turn more fully to the flame, warm himself through, but -- the sun was still lifting higher on the horizon, and Obito would certainly be missed if they were gone for much longer. With a last scrub of clean hands, Sasuke stood, facing his teacher with what he hoped was a neutral expression, and waited for the signal that they were moving again.
