I think Yvonne and Dani would get along well in and out of work, honestly. She prefers to be a pouty little thing when putting on a show so his bossing her around would be right up her alley - and then they can trade book recs and go to the dog park after hours. And he is so much bigger than her that I'm betting she daydreams about piggyback rides.
MISCHIEF YES. Cue the oversized hoodies with the drawstrings pulled tight so all you can see are her eyes and nose. When she asks Mouse to surprise her with a drink, she definitely means it.
She'll be happy to help Gideon with marketing if the need ever arises! She'll be advertising everything on her instagram anyhow, and she'll bring him his preferred drinks on particularly bad days.
