Wish and Mink won! Tavi on Pyxis was the first, then Braid and Charlie on Cygnus, then a big group with Wish, Mink, Spiky and Blade from Hydra, and that girl from Orion, named Carly I think. They were all granted a wish and returned home... well, aside from Wish, who gave his wish to help his sister.
The Judges aren't clear about what makes you win. But it's definitely starting to happen.
