The Royal Rumble Match
Roman Reigns, Daniel Bryan, Rusev, Bad News Barrett, Bray Wyatt, Dean Ambrose, Goldust, Stardust, Big Show, Kane, The Miz, Damien Mizdow, R-Truth, Dolph Ziggler, Ryback, Fandango and Luke Harper
Best Case Scenario: Dean Ambrose, on one leg, makes it to the final four, with Bray Wyatt, Daniel Bryan and Roman Reigns. At that point, he looks at Roman Reigns, and after eliminating Daniel Bryan/Bray Wyatt with his charm, he eliminates himself to a chorus of boos, completing his heel turn by being a good friend.
Worst Case Scenario: The crowd refuses to accept Roman Reigns victory, and storms the ring/backstage area calling for Vince McMahon be brought in on charges against adult fans everywhere. After capturing McMahon, they hold him for ransom until he can get CM Punk to come back, holing up in the Wells Fargo Center for weeks until they starve to death as a result of Punk never arriving because he simply does not give a shit about fans, especially obnoxious neckbeards who think the world revolves around them. Unless you are planning on buying his comics/UFC fights, of course.
What Nick Wants to Happen: Rusev to be both a player, and to crush a lot. ESPECIALLY if one John O. Cena wins the title match.
What Will Happen: A Final Four of Randy Orton, Roman Reigns, Rusev and Daniel Bryan, with Roman Reigns superman punching every one out of the ring at the same time and deciding to forgo a chance at the title against new champion John Cena, instead deciding to form a comedy duo with him called Super Pebbles.
