#3 He could confront 'The Beast'
Roman Reigns and Brock Lesnar are perhaps archenemies at this point, given the number of times 'The Big Dog' and 'The Beast Incarnate' have clashed over the WWE Universal Title. Now, partly thanks to Reigns' taking time off it's down to Reigns' close friend, Seth Rollins, to 'slay the Beast'.
But, the story being told could certainly not be hurt by having Reigns come face-to-face with Lesnar and confront him with the fact that he thinks Rollins has what it takes to beat him. Perhaps Reigns can even warn Brock Lesnar that just in case he does manage to hold on to the WWE Universal Title after WrestleMania, that he'll be coming for what was rightfully his.

Obviously I'm not advocating for Lesnar to start F-5ing Reigns all over the place, although I wouldn't put it past Lesnar's actual advocate Paul Heyman to suggest it. But a face-to-face confrontation between these two long-time foes will do wonders to reignite the feud between the two, help build Rollins' 'Mania title match, remind fans of where Reigns was before he left and help to set up Reigns' future when he's back.
