While i am an avid supporter of Arkos you have to admit it's pretty cliched. Pyrrha should've told him on the roof and made him actually think about what he really wants in a 'partner' if you catch my drift. Then he comes to the dance and he chooses Pyrrha. Not the most original but with a story like this it would do the best for character development, it would show Jaune actually has a brain as well as self-respect, choosing the girl that is willing to go above and beyond for him without asking anything in return rather than the girl he has to bend over backwards for just to get her to talk to him in a condescending manner. Not to say that i dislike Weiss but come on folks most dudes would've given up and moved on by that point.
