With nothing else to say for the moment, Sasuke was quiet for as long as Itachi was. The situation should have been far more awkward than it was, but with everything that was unfamiliar here, having his brother near him again was an odd sort of comfort.

"A day, no, two days ago. Worse yesterday. Before that it was just a lot of itching." He pointed to the back of his neck again, where the hair had grown. That sort of thing wasn't particularly painful, though still bothersome.

And this wasn't complaining, he told himself. Itachi needed details. "It's my spine, mostly." But of course everything was attached to that in some way. There was something going on with his tailbone and shoulders. He could only imagine what.
