I know someones gonna hate me for saying this...but I really do think if ruby and jaune live in the end of the series, they'll get together. they have screen time together, their teams hang out because they do, he's ruby's first friend, they have the same interests. and since they were on the same team for 6 months after volume 3, they must have a lot of development between each other. I can see them having 2 daughters at the end of rwby.
