Victory Screen
Every once in a while I have to wonder if the team making the victory animation talks to anyone else on the design team. Some of it's just silly like Nightcrawler dropping a mundane sword that buries itself in the ground or Beast pulling that book out of his jail pocket (imagine how good he'd be if he weren't toting that thing around!)
But the Overseer switches which hand his gauntlet is on! How did no one catch that?
