Last night, Jericho finally spoke for the first time since his return at the beginning of the month. All he stated was "This Sunday at the Royal Rumble, it's going to be the end of the world as you know it."
Very cryptic. Yet, it could be all too revealing.
Jericho simply winning the Rumble wouldn't make things the end of the world. While he has yet to win it in his storied career, I can't see that becoming the end of the world as you know it.
There was a rumor that Jericho would enter into a feud with CM Punk upon his return. Both have claimed they are the best in the world at what they do. During Jericho's promos for his return, he always claimed he would be returning to reclaim what is rightfully his.
At some point during the match between Ziggler and Punk, look for Johnny Ace to get attacked by CM Punk. This is going to open up the opportunity for Jericho to interfere and attack Punk from behind, and ensuring the win for Ziggler.
