The person who sent the Text Message and the person who used to send emails to Micheal Cole... are the same person, and when we find out who sent them, we'll see who the GM is. And my money, is on Chris Jericho. If you'll hold up, I'll explain why.
1. Chris Jericho's free from Touring and he's not doing anything. If people seriously think that he'll publicly announce his return and spoil such a huge return, then you're kidding yourself. Jericho is a Wrestler's Wrestler. He still finds a way to work the kayfabe even in reality.
2. How did Jericho have access to the phone? Simple... he found it laying around somewhere and saw Nash's number. He then proceeded to text Nash telling him to stick the winner.
3. How does he fit in to this as GM? Again, it's simple. Since Triple H's involvement with the company, the Raw GM has been silenced and that gives the Raw GM motive to do so.
4. How does Jericho fit in as a competitor? Yet another simple answer. Jericho's never been able to beat Triple H or John Cena, and with CM Punk going around claiming to be the Best in the World, it gets him kind of ticked off. Plus, the match was being built for the "Undisputed WWE Championship"... who is the first Undisputed Champion in WWE history? If your answer isn't Jericho, then you're ******ed.
5. What makes me so sure it's Jericho? Honestly, I'm not so sure... but in all honesty, it's a likely candidate due to him needing some form of return sooner or later.
