Well Kane asking if he's alive or dead seals that it was Taker. Kane was probably in on it too. The Brothers if Destruction are getting ready to run roughshod over Raw. You saw tonight when the light collapsed during the CM Punk interview.
Nothing mysterious happens in WWE without Taker being involved.
Maybe maybe, but there could be some other explanations to it all.
Firstly the lights crashing down.... Could be the Phenom, Could just be to signify the whole, RAW is lost without a leader like Mcmahon angle. Not that if Vince was there, he could have personally stopped a light falling down or an estranged fan running around backstage. Either way this, to me, seems like WWE are trying to convey a point that RAW is falling apart.
This is on top of Shane and Stephanie making the speeches along the lines of "we need to pull together", and the announcers cosistatly druming into our heads the importance of teamwork and unity, (anyone else get that?).
I cannot clearly see a big picture, but i think there is definatley something there.
Either that or I'm just over-estimating the WWE, I mean how capable are the writers of coming up with an interesting complex angle which cleverly progresses without explaining any unusual activities on the Undertakers supposed "powers".
Now onto the Kane shouting "is he alive or dead" thing. Beats me, he could be talking about anyone, could be Mcmahon, could be Taker, could be unrelated to any of these things. Hell, Kane doesn't have the reputation of being intelegent, and he hasn't been on RAW for a while, maybe he just wants to know where JR is nowadays, he did attack the announce team after all.
Then again, Kane shouts random irrelevant stuff all of the time for no reason. He used to freak out about may 19th, but only once in his 10+ year career have i seen him get pissy in the first three weeks of may.
But the "alive or dead" thing being in the main event would obviously assume that this is something big and important. Mcmahon is the biggest unexplained story at the moment and there is a strong possibility that the two are related, but it's not definate... Yet.
If The Undertaker is comming back soon, it is highly probable that this is the reason his brother went on a rampage. How many other times does Kane take the last minutes of a show, unless the Deadman is right behind him.
