#1 - The Dark Order gain a powerful member
The Dark Order, despite Brodie Lee's protests otherwise, is basically the dictionary definition of a cult. And what do cults do better than anything else? Recruit members.
We've already seen it - with Alex Reynolds, John Silver, '10' and others - The Dark Order and Brodie Lee have slowly been building a large army of wrestlers. But, what if they expanded? What if they moved into non-wrestling roles that would benefit them in the long term? Enter: a referee.
While Rick Knox is in the above picture, any referee (probably with the exception of Aubrey Edwards due to how over she is with fans) could be used in this role. Have Brodie Lee and Jon Moxley compete for the majority of the match, before Moxley is attacked by Dark Order minions, or 'The Exalted One' cheats in some way. Despite the rules being broken, the referee inexplicably lets it go and allows Lee to win the title in an unjust way.
This could be a slow burn of a story, with fans slowly coming to the conclusion that when the specific referee is the official for a Dark Order match, the group always somehow manages to win. I think it's a cool idea to have a non-wrestling figure be involved with the faction, especially a referee who can influence matches.
The eventual reveal would need to be backed up with a strong storyline explanation afterwards. Brodie Lee, though, is a character that has always been good at influencing others. With the right execution, AEW can pull this sort of story off perfectly.
