OMG 7 pages of random shit.
It's obvious why Kane and Henry aren't feuding, besides Henry being injured. It's because the WWE doesn't have to have continuity with their storylines. Remember when Barrett jumped The Undertaker? Taker never got revenge for that, and had a Wrestlemania match with Triple H after that. Just like when Jericho returns, hes not going after Orton (who took him out) but CM Punk.
Kane feuding with Cena is a way for the WWE to make Kane more relevant and over with the fans, like how he was back then. And Cena will benefit from this feud just as much as Kane, by being made to look like he can overcome anything, as well as getting more serious. We need a more serious Cena at Mania, and feuds like this one are going build towards that.
