"Would the Lady Representative care for a dance?"
Diana and Cornelius being all fancypants at one of the disgustingly luxurious formal functions they're routinely 'obliged' to attend as politicians. Cornelius in particular likes to complain about parties, but what's new. He enjoys them.
He secretly enjoys dancing as well, something he loathed learning growing up but rather sees the point of now that he has a partner. In this moment he must just be flirting, however, because he cannot begin to dance as a monster thing. The tail clears the floor and flipper feet are ungraceful and statures are a little mismatched. Oh well. They'll just be forced to go snuggle in the garden or something lame like that.
Background is repainted directly from a rather famous ballroom scene I've always worshiped the color scheme of. Anybody recognize it? Go on. Guess. Be our guest.
