Oh my God, I bet that's the angle they run with.
Paul Bearer has had the real Kane locked up again, and he just escaped!
It makes an odd sort of sense. Why Kane was the "happy freak" character in fall 2002, why it took only one tombstone for Taker to beat him at WMXX, why he suddenly had the desire to have a family via Lita in 2004.
I can see them using it as a ret con for the past 4 years of crap they've done to the character.
Kane has more retcon than Superman's origins.
So there's an Earth-1 Kane and an Earth-2 Kane?
It all makes sense.
Now all we need is for Owen Hart to come back from the dead via one of Kaneboy-Prime's punches, and we're all set.
