At Survivor Series, Roman Reigns defeated Dean Ambrose to win the WWE World Heavyweight Title. Shortly afterwards, he was dethroned by Sheamus, who cashed in the 'Money In The Bank' briefcase. Ambrose was nowhere to be found, and there were similar circumstances on Raw. When Barrett, Sheamus and Rusev ganged up on Reigns, why wasn't Ambrose booked to run down? One major story WWE have been telling throughout 2015 is that Roman Reigns and Dean Ambrose are friends who look out for one another. That was conveniently forgotten in order to book Reigns to fight off The Authority with a steel chair. Even though he managed, Reigns would logically be more than a little peeved at his buddy, who hasn't exactly had his back lately. Stories require continuity and sound logic if they're going to make sense. It's believable that Reigns would be angry at Ambrose for not helping him out. Firing back, the 'Lunatic Fringe' could distance himself from the situation by saying Reigns likes to always try and be the martyr. That cost him at Survivor Series, and it's not how Roman used to operate.
