#2. Hope is true: Backstage fear led to WWE finally splitting Sasha Banks and Bayley

It was a long time in the making, and it finally happened. WWE pulled the trigger on the Bayley-Sasha Banks angle. While it was reportedly planned multiple times before (including a program for WrestleMania 36), various circumstances led to the split being delayed until post-Payback, where Bayley finally turned on Sasha Banks and brutally assaulted her, writing her out of WWE TV.
Tom Colohue discussed the split on Dropkick DiSKussions and said that there was a lot of backstage fear that it would be too late to pull the trigger on the break-up, which is why WWE finally went ahead with it:

"I think there was a fear that it was just too late or it was very much becoming too late, so they just want to get it done. I am not aware that this was the original plan as it were, I don't know what the original plan was, I do know that they need a big match, particularly a women's match for Hell in a Cell. Last I heard, they wanted one big men's match and one big women's match, so this would certainly fill that spot, wouldn't it? We don't really have an intense feud on RAW in the women's division, and until this, we didn't really have one on the SmackDOwn side either. So it's good that it finally happened. Outside of that, both women have done pretty much everything they possibly could as a tag team. So it was more than time. They have been teasing this for years and constantly pulling back."
We hope this is true because the split was long overdue. While we're not sure when Sasha Banks will return to WWE, we can only hope that it leads to a bigger program when she returns. Ideally, keeping them apart until WrestleMania would be the best way to culminate their long-standing program and alliance.
