WWE Day 1 - Five potential finishes to Roman Reigns vs. Brock Lesnar for the Universal Championship: Hall of Famer returns; Paul Heyman chooses sides?

#4. Paul Heyman reunites with Roman Reigns to help him win at WWE Day 1

Roman Reigns fired Paul Heyman just weeks before WWE Day 1. The two men had a great run together, but it looks like The Tribal Chief doesn't require The Wise Man's services anymore.

Reigns will walk out for his Universal Championship match without Heyman at Day 1. Meanwhile, it's likely Brock Lesnar won't have the latter by his side either at the event.

WWE could look to pull off a swerve at the event and allow Heyman to come to The Tribal Chief's aid at a crucial moment.

Heyman could come out and throw in the Universal Championship for Reigns to use during the contest to help him win at Day 1. By doing so, he would win back The Tribal Chief's trust.

Reigns and Paul Heyman have worked exceptionally well together for over a year now. WWE could bring the two back together to build another top storyline for Royal Rumble and WrestleMania.
