@ Headstand Cyclops: Kathryn did not spend the whole move trying to get him to sleep with her; they did a wager, and if he won, she would -naturally- sleep with him, as his price. But, facts are, she did in fact want him, after all, she just wasn’t willing to admit it, ’cause of her pride. But there’s no such thing as she lusting after Sebastian the whole movie. He was the one who always wanted her; it is, therefore, possible that she always wanted him, as well, ever since their parents gor married. But, the truth of the matter is, Sebastian only rejected her at near the end of the movie, when he was supposedly already in love with Annette — though many could argue that he was never actually truly in love with her. I’ve always had the feeling that Sebastian always only really loved Kathryn. He always put her on a pedestal; after Kathryn, somewhat, opened his eyes, and showed him that he wouldn’t go long with Annette, he went there and broke up with her, as she’d want him to do. After both Kathryn & Sebastian had that talk in his room, he even says to Annette that there was only one woman he ever loved, and she didn’t even compare to her; then, he goes back to Kathryn, wanting to sleep with her, and, I assume, already forgetting of his "love", but that’s when *Kathryn* rejects him, so he runs back to Annette again. He, obviously, didn’t have a clue what love was, nor what to do with his life. It was a twisted game that Kathryn & Sebastian liked to play, that obviously wouldn’t end well.
As to the screencaps, as mentioned above, Kathryn firts humiliates Sebastian, saying that he’s a toy she likes to play with, so he slaps her, although, the second he does, he regrets it. Though she explodes, and starts hitting him, so they fall to the ground and all. This scene was cut, not ’cause it see seems too rough or anything, it was actually to make Sebastian seem like a better person, whilst making Kathryn seem even more heartless. So when she’d call Ronald later, it’d seem that she was lying about the fact that Sebastian hit her and then took off, so that Sebastian’s death would automatically make it even more Kathryn’s fault.
I really don’t think it should’ve been cut; in the end, not only Kathryn was the "villain", Sebastian was also to blame. But, of course, the students didn’t know about his little "bets", ’cause he obivously didn’t write any craps about him in his own diary, and I’m thinking Annette must’ve ripped out any pages that said something negative about him, or his conquests.
Sorry, I guess I just get carried away, while thinking about this movie. I just find it so fascinating, with such originality. ^^
