#4. The Rock and Elias in a concert.
WrestleMania 35 is assumed to last over eight humongous hours. While as a consumer, it feels good to witness eight hours of wrestling, the fans may get exhausted by such a long event. The length of the event may be stretched even further to accommodate The Rock. The Great One had a segment lasting around 60 minutes during WrestleMania 32, which dragged the PPV longer than what it would have been.
Elias, the musical prodigy, is not scheduled to be in a match at the 2019 edition of WrestleMania. However, Elias promised us that he would give us his performance of a lifetime at WrestleMania 35. What if "the Most Electrifying man in all of Sports Entertainment" interrupts the Drifter?
We could get to see a face-off between the Rock and Elias in a musical segment.
