#1 The "Paul Heyman Effect"
Now let us just preface this by mentioning that we don't mean to say that Paul Heyman came up with the idea of AJ Styles turning heel. It was evident from the direction of the storyline, dating back to even Stomping Grounds, that AJ Styles was eventually going to turn heel with The Club.
However, WWE knew well that a large chunk of the audience would be tuning in due to the news about Paul Heyman taking over as Executive Director of RAW. Overseeing the creative, WWE and Heyman himself probably felt that it was best to end the episode with a big twist and that's why they decided to pull the trigger on the heel turn when they did.
A top AEW star just called one of his colleagues 'spoiled' and 'narcissistic' HERE.
It obviously made for a very interesting segment and topped off what was actually a really solid episode. That's an A for Heyman!
