Styles noted how they had previously wrestled in front of smaller crowds, and the comment broke the tension for Dain ahead of his match."It was very cool because I was, I'll tell you right, I was about to make my entrance, and AJ Styles comes over to me because we'd been on a bunch of shows for a couple of years leading up to that, but one particular show was that January. So literally like before AJ went to the Rumble, we did a tour in Britain, and I think there was only 200 people in the building. So, he's laughing at me, saying, you know, 'From 200 people to this?' So like, that was pretty cool, AJ is a character, and it was very cool that he said that. It maybe broke the tension for me," revealed Killian Dain.GiGi @iam_gigi1_LINKKillian Dain deserves a second chance 🤷🏽‍♀️We at Sportskeeda Wrestling would like to send our condolences to Killian Dain at this difficult time.
