I'd expect her to lose. I don't think it particularly matters who the opponent is, though, so saying she's screwed by facing any particular one is incorrect. In this sort of tournament they should be able to beat anybody. After all, if there was somebody they couldn't beat, they would have already lost because ultimately they would have to face the person anyway in the final match if not before. Or a person who was able to beat the one they couldn't have beaten, and was thus even more dangerous an opponent. So, they need to have the confidence to beat anybody. It's not good enough to merely aim to be within the top 10 or something.

Souma could have said some nicer words to Alice. I don't think she would have taken them as condescending if they weren't overly obviously so. Maybe he would have, had he known more about her not so warm past. It's not like Souma would have been her real enemy, it's the sister and the rest of the family. That much she has made evident, though, by associating with Souma so freely. But then again, she was always looking down on him, not really seriously considering him a rival, so who knows what will happen in the future. I hope her relationship with Souma won't turn sour.
