GRETA -- has... no idea who she is, except the surname might ring some bells because of Peadar? Otherwise..... yeah.
EDWARD -- UM... well, it's entirely possible that he knows who she is because of Auror-ing, or WILL know her because of that, so... there's that! She's like 10 years older though, and he'd probably be actually shell-shocked around her and quiet, so. :|
DUNG: thinks she's FANTASTIC. they should drink together.
DOUGLAS: UM... well, I know we talked about the families being sort of distantly related, but she's only a year below him (he was Head Boy too, so would he have gotten her in trouble? ;D) so there could have been some sort of relationship instead. or... I don't know, she's a bit loud and brash for his liking. HMM. well, he'd be friendly anyway.
