#2 Sasha Banks' mistake costs Bayley the match
Traditionally, WWE has built friction between two best friends by booking one of them to cost the other his/her match. The Creative team has already booked a segment where Bayley's mistake cost Sasha Banks a spot in the Money in the Bank ladder match. In the same way, 'The Blueprint' could unintentionally cost Bayley a victory against Charlotte Flair.
WWE needs to protect both the women in this contest because both hold the number one position on their respective brands. A clean victory for either female Superstar may not go down well with the fans. Hence, an outside interference would be the best way of ending this match.
Will Sasha Banks finally betray Bayley?
Bayley could dominate Charlotte Flair in the initial phases of the bout. She would almost seal the deal with her finisher. However, Sasha's untimely distraction would not allow the referee to concentrate on the pinfall. Otherwise, Banks could try to give a weapon to her friend, which would instead help Charlotte win the bout.
Thus, these are the ways WWE can have Banks lead to Bayley's defeat against Charlotte Flair. This booking technique would ensure the alliance implodes soon.
