[Claude glances up to assess Byleth's reaction and whether he has permission to continue, and when he says it doesn't hurt, offers a small, relieved smile, adding a little more pressure and beginning to make a circular motion with his fingers.]

Good. I'm no expert, but I overheard at the infirmary once that this sort of thing can help scar tissue heal better.

[And it does feel like there's a lot of bunched-up tension there, from the way Byleth seems to relax into it, so even without the old injury, this woukd be beneficial. He's grateful, honoured even, to possess such trust.]

You've been through a lot... and no doubt you'll go through a lot more in the times ahead. So knowing when to give yourself a chance to relax is a good thing.

[He's partly chatting to fill the silence, but also partly praising him for stepping up earlier to help people have fun. It's nice to see him want to enjoy himself.]
