What-If Roman Reigns got amnesia from that curb stomp from the Royal Rumble?
He wakes up thinking it's 2013 again. He still thinks he's part of The S.H.I.E.L.D and comes back wearing tactical gear. He notices Dean Ambrose missing and seeks Seth Rollins' help to find Dean. Roman at first will be like wtf is Seth wearing.
Seth Rollins not knowing what to think, reluctantly plays along.
Weeks go by and flashes of memory start coming back to Roman, driving a wedge between him and Seth.
Seth snaps and repeats the infamous chair shot to Roman, finally awakening him.
Our Tribal Chief has been restored, and goes on to WrestleMania and defeats Seth Rollins once and for all!
