I say this could be the start of it he is still injured and coming to do the match with Del Rio with him attacking his arm could lead to his real-life retirement.It only takes one big mistake so I say keep this match slow have Del Rio target his other arm instead of the injured one.Have Cole say that's the one tha't injured but have Cena go super cena and reverse the cross armbreaker and hit the AA.Act hurt before pinning him after celebrate as Del Rio hits an arm enziguri then armbar Sandow cash in on Cena biggest win of his career.Cena comes out the next night like Triple H did and say's he don't know if he can go anymore only to return during the road and turn heel (finally).He don't do TV matches anymore or be on every tv taping he just do like every other week like the other ones.After Mania...
A-Retire after beating Taker at Mania
B-Leave Again or go Part-time
C-Stay for Extreme Rules leave come back for Summerslam
D-Don't go Part Time and start a heel Faction
His Opponent for Mania Should be
The Undertaker (Cena Heel Turn)
Hulk Hogan (Cena Heel Turn)
Stone Cold (Cena Heel Turn)
Daniel Bryan (Cena Heel Turn)
Triple H (Cena stay's face)
Randy Orton (Cena stay's face)
