[quote=Imperfectionist]Belasco, well, it kind of depends on how he treats her (and some of the other Hogwarts girls, like Amelia and Lydia... esp. Amelia). If he's just an instant bag of dicks, there's no way she'll be able to like him, but if he seems to just be, um, [i]driven[/i], they'll be more likely to connect. In any case, she'll definitely love having a duelist that's likely to beat her in the group. ;) Gives her something to look forward to later on.

Sounds like there's a possibility to make a connection, then. :)
Johann isn't a bag of dicks, just a bit of a bigot. While he's going to accidentally patronise the womanfolk and be a bit twitchy about the half-breeds and muggle-borns that seem to constitute the other males in the group, he probably won't be outright rude, and he'll happily change his mind if/when any of them prove themselves to him. If anything, all a woman has to do to get him to like her is to not act like a squealing girly bundle of hormones and he'll be incredibly (if patronisingly) impressed.
