#3 John Cena interrupting Elias at WrestleMania 35

Who will it be?
While the true answer to that question is whoever the hell WWE decides it's going to be, there is now at least some reason to believe that it will be John Cena that ends up interrupting Elias during his performance at WrestleMania 35. In fact, WWE hinted as much during Elias's interview on a moment of Bliss.

Of course, the reference was very subtle, especially since Elias didn't name drop anyone, but if fans remember correctly, it was John Cena that interrupted Elias's performance last year. Elias even went so far as to say that it was the reason why this year's performance at WrestleMania 35 is so important to him.
In the end, it's not a guarantee by any means, but it's pretty easy to imagine Elias running his mouth to The WWE Universe during his performance and ultimately getting Cena's attention in the process. Cena can then make his way to the ring and they can have the match that WWE had planned for them years ago, which would be a huge boost for Elias's career if he can win.
