Harry Potter and the Goblet of Fire2005

[Hermione is Krum's date at the Yule Ball; Ron is clearly jealous]

Ron:
[about Krum] He’s using you.

Hermione:
How dare you! Besides, I can take care of myself.

Ron:
Doubt it, he’s way too old.

Hermione:
What? Is that what you think?

Ron:
Yeah, that’s what I think!

Hermione:
[on the verge of tears] You know the solution then, don’t you?

Ron:
Go on.

Hermione:
Next time there’s a ball, pluck up the courage and ask me before somebody else does, and not as a last resort!

Ron:
Well... that-that-that... that’s just completely off the point. [sees Harry approaching] Harry.

Hermione:
Where have you been? Never mind. Off to bed, both of you!

Ron:
They get scary when they get older.

Hermione:
Ron, you spoiled EVERYTHING!! [Breaks down in tears on the stairs]
