after nexus helped kane bury the undertaker alive, why did he came and help team smackdown get rid of nexus???
This, I don't think Nexus really cared about Kane but wanted the Undertaker. Whatever reason Nexus attacked, it will proberly be revealed when Taker returns.Maybe Nexus weren't helping Kane, but hurting Taker.
Or that Kane was offended by the insinuation that he couldn't get it done on his own.We are to believe that Kane and Nexus/Barrett made some sort of deal, but there was a falling out between the two since one of them broke their word. That or Kane's insane and turned on them any way because he's a monster!
