>>14127756AEW booed him because he was forcing himself to be the baby face. They dealt with it for so long but after awhile, every character has a natural progression into a heel. Cody was long overdue for that transition and even teased at a heel turn when he died his hair black and started wearing all black gear. Then he went right back to forcing baby face. At this time, he was getting relentlessly booed every week until he stopped showing up.
Then he got the WWE deal where the fans are again back to dealing with his forced baby face. This time he has no where to run and has to make the heel turn or the crowd will turn on him naturally.
