Hahaha, these two old battle maniacs!!! Them grinning like that cracks me up.
Honestly i found this chapter really cheering. I actually have an incredibly chronic pain issue that involves my back a lot. I really find myself enjoying the sympathetic way Tygnis' pain is being treated. I especially enjoy the focus on learning how to be aware of your body, and finding ways to do physical therapy without triggering the pain you're already in.
It's genuinely very good advice, especially since it's being paired with treatment, and even consideration to 'well lets at least get you doing something that feels a little cool to do'. Morale is genuinely helpful in any devotional practice, I think. From art to martial arts.
