Zaveid I am cool with her knowing, but it would be really weird if she calls him Filk=Zadeya (Zaveid of the Promise) because that's some True Name nonsense right there.
Shin-Ah go for it. She might know he was just "Seiryuu" (blue dragon-) until a couple months ago.
Daikaku go for it? have fun, he does only have a couple of weeks of lifespan left-
Volga Sure?
Duke Yes have fun?
