That sounds like exactly the kind of thing Danse will find both reassuringly familiar (in the "hello fellow person who doesn't know what to do with himself outside the military" sense) and absolutely horrifying (in the "we should probably both not exist" sense), so I am absolutely down to throw them together and see how it goes!

They can commiserate over diet changes, too, because Danse is going through similar ones and having a rough time of it, and he might be one of the people willing to urge Sephiroth to be more practical about it.
