1. Seth Rollins Didn't Know He Was Cashing In
If Seth Rollins looked surprised and emotional whilst celebrating with the WWE World Heavyweight Title at the end of WrestleMania 31, that's because he was genuinely surprised and taken aback at what had just happened. Going into 'Mania, the plan was for Roman Reigns to leave as champion, with Rollins then cashing in at a later date. As The Rock was inviting Ronda Rousey into the ring to confront both Triple H and Stephanie, Rollins was informed behind the curtain that he'd be interfering in the main event and leaving with the belt. Brock Lesnar, Roman Reigns, Paul Heyman and Rollins were all called into a room, tasked with ironing out exactly how the finish would go down. Less than 2 hours later, Seth Rollins was WWE Champion, and must have felt on top of the world. For Reigns, it must have been a huge disappointment, especially - as aforementioned - with the knowledge that his family were in attendance to witness his big moment. For Rollins, it must have been a case of having to contain his excitement somewhat backstage, knowing that his friend would be hurting, but that proved impossible out in the arena. Swinging the strap wildly around his head on the entrance ramp, Seth appeared to be a little kid again, dreaming of a moment that had now come true.
