Yeah, realistically there would be no happy ending for the main six. They all should have stayed Ci'eth or stayed crystal. It took Fang and Vanille seven hundred years to wake up, and even then it was only because the fal'Cie had another job for them to do. I don't mind the happy ending though. It made me feel warm and fuzzy :3

Everything between the first and last Orphan fight was really amazing!
