Possible SPOILER Regarding NXT Female Superstar Invasion Storyline

According to Bryan Alvarez of The Wrestling Observer Newsletter, he heard a rumor about a possible storyline involving the recent NXT female Superstars who were called up to the main roster. He heard that one idea that's been tossed around is to reveal that there was one mastermind behind both the Raw and SmackDown Live factions:

“I don’t know if this is going to happen but I heard that one of the ideas they had was that it would come out that Paige was behind both invasions. How they would do that, I have no idea because there’s a Raw brand and a Smackdown brand [and] it doesn’t make any sense if they’re not doing the interbrand stuff except during Survivor Series.”
