8 Booking Steps For The Undertaker's WWE SummerSlam 2018 Return

5. Roman Reigns Moans About 'Taker's Comeback

That challenge from The Undertaker to Brock Lesnar would infuriate Roman Reigns.

The next week, he'd be looking for answers from Kurt Angle. Before Brock big-leagued everyone, Reigns was preparing for a multi-man contendership match at Extreme Rules. Then, after Lesnar's puppet Paul Heyman found some contractual loophole, the match was cancelled. Now, 'Taker is muscling in on the scene.

Much of Roman's character since April's Greatest Royal Rumble has revolved around the idea he's been cheated and is the rightful Universal Champion. That must continue if WWE want involvement from The Undertaker to be treated with any credibility; Reigns cannot be happy or sit quietly on the sidelines.

To Angle's continued dismay, Roman would then tear down The Undertaker, remind everyone he beat him at WrestleMania 33 and question Kurt's ability to call the shots. The verbal beating Reigns gives 'Taker should be so severe that the legend is left with no option but to respond.
