#3- Back to NXT
There were recent reports WWE was considering another Superstar Shake-Up very soon. Some stars might even be moved from the main roster back down to NXT, if rumors are to be believed. There could be any number of reasons for someone's move back down to NXT and not all of them are bad.
WWE could think they need to repackage someone or the creative team may not have anything for them, at the moment. They could think a particular Superstar would be a value addition to WWE's developmental territory. All are plausible excuses to send someone to the WWE Performance Center for another run.
After all, there's still time to insert Paige into the match at NXT TakeOver: Houston to determine who's going to claim the NXT Women's Title, after Asuka vacated it.
If she spent some time in NXT it would not only elevate the brand but also supply her with ample opportunity to help others learn from her experience, and even learn a few tricks, herself.
