This feud between Roman Reigns and Kevin Owens worked wonders in showcasing as the champion as a dominant force. But it also played its part in displaying his vulnerability when he's left alone. He won the first two matches with Jey Uso's help, and Paul Heyman made all the difference at WWE Royal Rumble.

The interaction between Owens and Roman Reigns on the go-home show of SmackDown before Royal Rumble was more than just a "War of Words." Owens made Reigns visibly uncomfortable when he called him an insecure bully. The subtle details of his character and his recklessness expose a weakness that a future challenger could exploit.

WWE has ensured that this side of Reigns comes across as an Achilles’ heel rather than a specific weakness. Kevin Owens could revisit this feud somewhere down the line because he could claim that that Roman Reigns never earned a clean victory over him. The storytelling in this feud leaves the company with several potential directions as the road to WrestleMania continues.
