I'm with you there. There's a throw-away mention of her watching the Trio visit Hagrid at some point. Sure, it could be her spying, but what's the point of that? I think she's genuinely interested by now.

I think he's snapped - he's clearly not under the Imperius anymore when Harry and Krum meet him, as he wouldn't be there otherwise, but the excess use of it seems to have ruined his mind. At least temporarily.

I don't really get it either. It does make more sense if he simply doesn't believe Harry...

Yeah, typical Hagrid. And yet Karkaroff had a point, really - from his PoV it does all look very suspicious. Although surely he must realize Voldemort's impending return might have to do something with it as well.

I saw that too, and yes, that was the theory. Equally interesting is that in the fact of Ron's criticisms, George suddenly ignores his own reservations and goes through with it after all - he's the one who sends the letter in the end.

Yeah, we knew that, but confirmation again, and early hints of the Ministry not being too willing to see the writing on the wall.

*nods* It becomes stronger when we actually see them in the next book, but yeah. There are other cases like it, of course - Snape in a way, and Luna comes to mind as well. No wonder then that Neville and Luna end up together, perhaps.
