Chris Jericho spoke out about his appearance at All In on his official podcast.
"Months ago, when All In was announced, Cody called me and said, 'Do you want to be involved?' I said, 'No, I'm not really one to work any shows in the States that aren't WWE shows.'
For various reasons I just didn't feel like it was where I was at career-wise. I told him that I appreciated the offer, but I'm not going to do it. I also got asked to do Long Beach and those New Japan shows as well.
Over the course of the last few months, my mindset has changed a bit to where I'm enjoying being part of this new revolution of wrestling. I thought I would consider it, but the idea has to be right.
Cody called me again and I started thinking, 'I wonder if I could make this work.' The idea was 'what if I could come in earlier in the show and attack Kenny?' The idea was to keep the angle alive from the Tokyo Dome to the Cruise."
