Logic: The build for this matchup started as soon as we saw a quick clip of John Cena in one of Kane's return promos. On the very same night on Raw, Kane did indeed appear and ended up planting Cena with a chokeslam to close out the show.
In addition to that instance, the company has been throwing Kane at Cena during recent house shows. This perhaps indicates a possible feud between the two. But either way, this is going to happen. Cena has to be kept busy until his match against The Great One at WrestleMania, and Kane seems likely to be his guy.
Wishful Thinking: I think the IWC can agree that Kane's character has been in a steady decline ever since he took off that mask a number of years ago. Since then, he has had one meaningless World Title run. One in which he cashed in his MITB briefcase against a vulnerable Rey Mysterio.
But it's not even the one major strap that really put the legitimacy of his character in question. It's the fact that Kane was never really booked as good as he previously was. Instead of kicking ass and taking names, we're seeing Kane doing the Santino trumpet dance.
Perhaps a clash with Cena, the WWE's top guy, can bring back THE Big Red Machine. The one with a mask that didn't talk and didn't give a damn about who stood in his way.
As far as the result of the match, I would have anything happen where Kane is on top. Whether it's Kane destroying Cena through a disqualification or Kane actually picking up a pinfall over Cena, the Big Red Machine has to get the better of the Fruity Pebble.
This would make Kane seem more relevant right after his big rebuilding and keep the "breaking down of Cena" angle going into his Rocky match.
