Ah yes. Waterswimmer would look for any excuse to gather more anatomical information on the insides of non-hylotls. I have very fond memories of being asked for advice of how to make a gruesome murder scene. Good times. I knew those Warhammer 40K RP sessions with Chaooos would come in handy again!
I'd say only highly intelligent/experienced engineers or fellow glitch / glitch blacksmiths would be able to fix any "serious" forms of damage inflicted on a Glitch... I also don't think they can repair themselves... (for instance, repairing their own severed limb, i don't think they can reach that part properly, for instance: while using only one arm, or at least it'd be very difficult/awkward.)
Main thing about Glitch is that self-repairs are awkward. They're reliant on kinsmen or outsiders with sufficient technical knowledge for repairs.
