the way they debuted Dexter on Raw was designed to where if you knew who he was you were like
and if you didn't you were supposed to be confused/intrigued because he was in the background getting hauled off by cops. Yeah they name dropped him on commentary but you're supposed to be left wondering what he was doing and who he is to some degree. It's (seemingly) connected to a storyline that just kicked off where you want to find out more.
AEW brings out random Japanese people or indie wrestlers for one off matches versus their champions without any story or build and then you may never see them again. That Mance loser just gets a match against the world champion for seemingly no reason, there was that Japanese chick who wrestled Thunder Rosa and tanked the ratings that week, none of those matches had anything resembling a storyline to justify them.
