#2 Royal Rumble betrayals: The cracks will appear between Randy Orton and Riddle
Randy Orton and Riddle have been some of the best parts of WWE TV over the last year. The unlikely chemistry between the two has done wonders. However, WWE fans know that all tag teams come with a timer. Most of them break up, and the partners who had been working so well together start feuding.
Orton and Riddle will likely break up at some point soon, and the first cracks could show themselves at the Royal Rumble. In the spirit of competition, if Riddle eliminates Orton this year, then the two of them will eventually begin feuding.
Orton does not appreciate others getting in the way of his success, and he would not tolerate something like this. It could also be the starting point of their feud heading into WrestleMania.
#1 Royal Rumble betrayals: Paul Heyman will betray Brock Lesnar
Paul Heyman conveniently reunited with Brock Lesnar soon after the Beast Incarnate's return. He is currently siding with the WWE Champ as he defends his title against Bobby Lashley.
However, if he is only pretending to side with Lesnar and is still working for Roman Reigns, this would be the perfect chance to betray Lesnar and cost him the title. That would lead to Lesnar hunting him down and eventually going after Reigns, resuming the feud from WWE Day 1.
