Hermione Granger

"A few," Elle says, and while she's a teeny bit embarrassed to get caught talking to herself, she's pleased to see Ron. It's really just silly that she hasn't met him yet, but now is a fantastic time to rectify it. "But this was especially lovely. Congratulations. I'm Elle." She's sure Hermione has mentioned her in passing — she's on the guest list, after all — but beyond that, she has no idea if he knows who she is. It doesn't really matter, though; he will now.
