Assuming her catsuit is made of Valkoran Nanofibers, it is impervious to water splashes.
I have been thinking about some gratuitous repair benefits though.
Still need to think about how to integrate those...
Thinking about the repairs event.
It could be used to trigger something with another character,
ie.
In the morning T'Ris reports that "Nothing needs repairing today"
after which the MC thinks "Good, I think I will visit T'Ris this evening"
In the evening while the MC and T'Ris are engaged ,
someone walks in on them to report a problem with the ship!
This could open up a threesome route, start a Harem route, open up dating the other character.
or just change some of the Stats for T'Ris and /or the other character.
