Here's the video from Raw last night (Dec. 19, 2011) of Kane returning once again to attack John Cena.
The set up and execution of this entire segment was great. First, Cena comes out and gets the chance to do his silly comedy promo routine, which certainly isn't my cup of tea but some folks like it, so it's fine. Then, Mark Henry comes out and delivers the line of the night by telling Cena he can kick rocks.
All of this leads to Kane coming back out to tease attacking Henry before turning his attention to Cena once again, for reasons that are still unexplained. Except he didn't really do much to attack him. Essentially, Kane incapacitated Cena so he could rip Cena's shirt off and take off to the back with it.
My early theory, as mentioned here, is that Kane can represent the embodiment of Cena's subconscious, and the reason he ripped the Rise Above Hate t-shirt off and walked away with it is that it's high time Cena stops pushing that line and finally does what Roddy Piper was suggesting on Raw a few weeks back and "squares up" with the audience.
That might be a little too deep for a pro wrestling show but it's what sounds best to me. Anyone else got a theory on why things went down the way they did?
