Re: What will finally rattle John Cena?
The turn will be Cena getting sick of being the comic book hero, a 'pipe bomb' deal, ala Hogan at the Beach. McMahon will have a family planted front row and zoom into the mom/dad taking the crying child away, leaving the arena. There'll be uproar on the tard-iverse, like the time soccer moms rebelled over a mere cameo from Lesnar.
It'll only happen when the t-shirts stop shifting, thats when Hogan went for bust.
