Lavender Brown: [runs into the hospital wing, after Ron's been poisoned] Where is he? Where's my Won-Won? Has he been asking for me?
[sees Hermione sitting next to Ron's bed]
Lavender Brown: What is she doing here?
Hermione Granger: [stands] I might ask you the same question!
Lavender Brown: I happen to be his girlfriend!
Hermione Granger: Well, I happen to be his... friend.
Lavender Brown: Friend? Don't make me laugh! You haven't spoken in weeks. I guess you want to make up with him now that's he's suddenly all interesting!
Hermione Granger: He's been poisoned, you daft dimbo! And as a matter of fact, I've always found him interesting.
