RAWR! *hugs* Loves for you too and no worries! (really weird saying that logged in as Flint.)
Flint says Penny is a good healer and she's alright. (Which is big praise from him). He's wary of Alexander, especially if he knows his father. Flint Snr and Jr don't get along. I don't think he'd know Fleur at all, but never mind.
K LOVES PENNY-LANE! (That is her name, okay? Good.) She can spoil Elliot if she wants, most people do, haha. Fleur, I think they'd be on friendly terms, depending on if Bill's player is game for that back story friendship.
Fred may tease Fleur, but that's only because he likes her. Same goes for Penny. He would think she was a bit mental for dating Percy though. He says Alexander should shut his old man mouth and go back to his nursing home.
