The fact that he sounds surprised that it hurts is... well. Strange. He's a doctor, he should know that a real massage isn't going to be all fun. York gentles his touch, though, going at the knots slower, using his palm instead of knuckles. Maybe Ratchet's just never had one before, and he's used to doing this for people that are used to pain.

"If it hurts too much just tell me."
