Basically the whole of Krakoa voted for Rogue to break up with Gambit. There had to be a Survivor aspect to the island, right?
Marvel didn’t have the balls to put Gambit on the roster for fan votes, they knew he’d win.
Maybe it’ll be the moment Gambit realizes Rogue doesn’t actually love him, and he’ll slink off all butt-hurt and Rogue can continue to be the Good Guy and Gambit will just never be Good Enough.
