Regardless of how cool/interesting Gray is right now, he has abandoned his friends and single-handedly caused the entire Grand Magic Games mishap to happen due to his actions in Rogue's timeline (which apparently are entirely the same as what's happening now, minus the dragon attack in the past). That means that everything that's happening right now is Ultear's fault, which I think is nice considering we are tying up all the GMG's loose ends. It's times like these where I realize how much of a wonderful writer Mashima is~
