Cena continues his Superman run
The fans would love to see the last climax. However, in reality, we might be fed with this or the next one. If you take a look back the recent feuds of John Cena, we can see a pattern. He gets beaten up by his opponent in the start, only to come back stronger later into the storyline. Something similar could be expected from this feud as well.
The worst thing that could happen to Owens is this climax. Cena gets a squeaky clean win and it derails the entire momentum that Owens built over the months. This will have some really bad fallout but since we are talking about WWE and Cena, it is a big possibility on Sunday.
Neither Superman nor Kryptonite
If WWE does not want Cena to lose the match and they don’t want to bury Owens as well, then this is what they should go for. A botched ending where Cena wins via disqualification will protect both superstars. It will also help the WWE to set up a high profile third battle between the two which could happen inside a steel cage or even Hell in a Cell.
The ending could come due to Owens walking away or using some weapons. Walking away, however, will not suit his gimmick so the latter should be apt. Another possibility is interference from an outside character. This could then work as the base for a new John Cena feud. No matter what happens, Owens needs to be protected as he is too hot to be wasted.
