#2 Wyatt is doing the 'weird' gimmick
WWE is quite clearly invested in what Bray Wyatt is doing at the moment. It is clear that he has a big hand in the scripting that happens in all his segments. The symbolism is quite obvious and one can see for certain that it's Wyatt's devious mind behind all of what we get to see on screen.
What this essentially means is that WWE will not ideally want an overlap between two characters with similar gimmicks. This is why they are probably normalizing Nikki Cross, thereby making sure that one gimmick isn't confused for another. It is quite clear for now that Bray Wyatt doesn't want her to play the part of Sister Abigail, right now.
Charlotte Flair to return and wrestle a CURRENT CHAMPION?
Instead of a stable, I'm guessing that the Firefly Fun House will just be Bray Wyatt portraying various personas. I'm okay with this because Wyatt never disappoints.
