I somehow see HHH screwing Cena over then CM the next day is pissed off for HHH's actions. He says it was the sole reason why he left in the first place, blah blah blah...
Cena comes out and turns heel and says CM Punk is a genius and doesn't agree too CM's words. This sets Cena demanding a rematch but HHH says there isn't a rematch and he's in charge. HHH then pedigrees CM Punk and holds the title up high, therefore they feud.
Works for me... I just don't see HHH Calling it down the middle
Either way, CM Punk should win.
