She would 100% be watered down. I cannot imagine TNT being too thrilled at Maki constantly calling people fuckers or dropping other incredibly explicit not safe for ears content. There are rules in place where the FCC can fine broadcasters for explicit language if it airs before 10 PM. Which is why AEW is fairly liberal with its censors (even if they mess up the majority of the time and actually miss what they mean to censor).I'm hoping that Itoh wouldn't be "watered down" in AEW (no usage of mutherfucker/flipping the bird). If she went to WWE, that would be definite.
And I would put the odds of Maki going to WWE at "there's a better chance of someone here hitting the lottery".
