When I first came back (to AEW), it was pretty exciting. I didn’t know what was going to be happening in the near future, but I think the last time I was in this extreme dimension of y’all’s podcast, I said that in WWE, I felt like I was a ghost, just walking around backstage. Honestly, man, I kind of still feel like that at AEW, just because of not being involved in something cool. I feel like there’s something so special that we (Jeff and Matt) have within us to really bring out.
