Even if he's strong enough to move around now, Ryan is still a noncombatant. The best he can do is stay out of the way so that he doesn't have to be healed up again. Thankfully for Ryan, that at least is something he usually excels in, previous blow notwithstanding.

Once the fight is over and everyone is patched up (he can do first aid even if he lacks magic), he approaches Irisviel again, not quite making eye contact.

"That magic — is that something you learned here, or...?"
