The underwear on the outside

Dr. Staple (Sarah Paulson) treats people who think they are comic book characters. Her patients are David Dunn aka The Overseer, Kevin Wendell Crumb aka The Horde and Elijah Prince aka Mr. Glass (Bruce Willis, James McAvoy and Samuel L. Jackson respectively). Superhumans need to prove the good doctor and the rest of the world wrong. And it's utterly boring.
