After the shocking events of this past Wednesday, Don Callis will appear on AEW Dynamite to give his rationale for why he turned on Kenny Omega.

At the conclusion of Omega's cage match with Jon Moxley, Callis entered the ring and delivered a shot to Omega's head with a screwdriver, leading to Moxley getting the win.
