Seems a tad unrealistic, though. But okay.

Yes, quite a scare, poor Hermione... the good thing is it stops them both from being silly.

It's only a culmination of a longer evolution - he's been annoyed by Lavender before, and already pissed her off when under the love spell. It was a matter of time anyway, but no doubt this experience and Hermione's obvious display of interest helped speed things up.

Seems to me I hear people say "I love you" like that a lot in Hollywood films. What's special about this one, of course, is that it sounds like the platonic kind but likely was intended to have a deeper meaning. Still, hardly a declaration of romantic love.

But you really have to wonder why McGonagall have her the job...

That's possible, now that you mention it...

We don't really know what Draco is like because we only ever see the front he puts up for his Slytherin cronies and his Gryffindor enemies. So, well, why not. It's an interesting contrast with Voldemort in his Hogwarts period, though.

I was wondering why she wanted to see Dumbledore, but you must be right, she's probably asking him about Lupin and to call him off that mission... I've never had any problems with the thing between them, I'm plenty convinced.
