Callis called Jericho and told him his idea, and Jericho was immediately intrigued. Jericho’s very busy with WWE appearances, Fozzy shows and various other projects, but he thought this could be very cool. Callis then went to Omega and told him about the idea, and Omega was equally excited about it. NJPW booker, Gedo, was also determined to have Jericho work for NJPW at some point, so all this came together very quickly.
Jericho informs that at this point in his career he’s only going to pursue things that interest him, and this match versus Omega interested him from the start. He can go back to WWE for WrestleMania, but he knows he won’t be in the main event.

Instead, he’ll be slotted in the middle of the card somewhere, and if he’s not facing Lesnar or Strowman, he’ll be competing against someone he’s worked with a thousand times before already. For this reason, facing a new competitor like Omega at the top of the card at Wrestle Kingdom 12 is probably the most exciting thing he can think about doing at this moment.
Jericho thinks that this match makes him a bigger star in the wrestling business, and this helps WWE and McMahon in the long run. However, he was still nervous about bringing this up with McMahon and he wanted the deal to be locked in stone before finally calling McMahon.
