#2 Similar: The AEW rivalry mirrors Jericho-Owens' friend-turned-foe narrative
In AEW, MJF and Chris Jericho had a rocky beginning, but after the former and Wardlow were allowed to be part of The Inner Circle, the two constructed a friendly relationship. Their camaraderie was enhanced through comic sequences, and when MJF eventually duped him, Le Champion turned face.
In WWE, viewers observed Chris Jericho and Kevin Owens create an exemplary friendship. Both superstars were heels, and the setup involved comedy, with the List of Jericho fastened to the plot. When Owens attacked Jericho, it was Jericho who turned face and Owens remained a heel.
#2 Different: Jericho was prepared for the betrayal in AEW
One of the more striking contrasts between the rivalries lies in how Jericho handled the respective treacheries. In WWE, he was shocked by Owens' deception and the emotionally charged climate that established a memorable contemporary pro-wrestling moment.
Jericho did not completely trust MJF like he trusted Owens. Thus, when MJF betrayed him on AEW, Le Champion saw it coming and was prepared for it. He did not exhibit a rattled reaction similar to the Owens feud, and the primary surprise in AEW was the showing of The Pinnacle.
