Whatever Itachi planned on doing, Sasuke wasn't sure. He didn't scoot back, though part of him wanted to fight against this under the sheer insistence that he didn't need his big brother's help anymore. The louder part didn't want him to disappear again.

A hand found the front of his shirt - buttons, as it was the best replacement he could find - and began undoing it. This would let Itachi know the extent of the damage, and how far the fur went down. He didn't know if this was what the other ninja was even going for, but it was at least the best he could do to show him that he trusted him enough for this.

"Yeah."
