#3 Natalya gets mysteriously attacked

Natalya is set to face RAW Women's Champion Becky Lynch at SummerSlam next month but that doesn't really look like a match for one of WWE's biggest shows of the year. WWE could surprise us with a big angle on RAW tonight with someone taking out Natalya backstage.
The mystery attacker could turn out to be either Sasha Banks or even better, be eventually revealed as a heel Ronda Rousey, returning to reclaim the title she still looks upon as her own.
