I've thought about that, too. She never, ever does anything in the books without a purpopse, but that just leaves us to speculate on the possible implications of that first meeting. I know she's said she won't have any same-sex relationships in the series by the end, but the set-up is so completely there. There's nobody else in the entire series that Harry goes so far out of his way to impress (even if he's convinced himself it's just to show Draco he's the better of the two), and he's not shown any real interest in the girls, other than Cho, and we all know how THAT turned out. Draco's one of the few people who sees him, not as the "Saviour" everyone else does, but just another person, and I firmly believe that is something Harry needs, and even wants. He doesn't want to be put up on a pedastal and idolized, he just wants to be accepted for himself, faults and all. Draco's constantly jeering about Harry's faults in front of his friends, but he also, at the same time, seems to accept them on another level.
