#4. Chris Jericho puts over one of his proteges in Sammy Guevara
Sammy Guevara was placed with Chris Jericho quite early on into AEW's life and the young star has benefitted significantly from getting to work alongside someone as experienced as Jericho.
If MJF is Jericho's biggest success story in terms of building up new stars for AEW, then Guevara is certainly a close second. With that in mind if MJF isn't the one to retire Chris Jericho, then it really should be Sammy Guevara.

#3. Juventud Guerrera spoils the party and ends the trials of Chris Jericho
It seems extremely unlikely given the storyline builds and payoffs, but let's say that AEW want to be the biggest party pooper there has ever been and not give fans what they want.
They could achieve that by simply having Chris Jericho lose his next announced 'trial' against Juventud Guerrera, or at the very least not win the match with a top rope move. Jericho, having fallen short of getting revenge against MJF, would surely retire from wrestling out of shame.
It would probably earn the legendary luchador nuclear heat, and it would arguably be the biggest mistake AEW could possibly make. But there's an outside chance it could happen.
