“After weeks of cryptic “1-2-12” videos on Raw SuperShow, Chris Jericho made a shocking return and was warmly welcomed by the WWE Universe, greeting some with high-fives at ringside. As he urged them for more cheers, “#Y2J” instantly became the No. 1 worldwide trend on Twitter. But as the Superstar – who was dressed in a dazzling, light-up, blinged out jacket – prolonged his homecoming, the WWE Universe’s chants of “welcome back” soon turned to boos. A smiling Jericho exited without addressing the Memphis crowd, leaving the irritated WWE Universe wondering why he’s back.”
