#3 A Much Needed Double Turn
We have recently witnessed a double turn in the Bobby Lashley vs Kevin Owens match on Raw, so it is unlikely that this will happen. However, it most definitely should and is what's best for business.
Charlotte is a very capable in-ring performer, but, her character arc is much more believable and better in general as a heel than as a face. Lynch, on the other hand, is almost impossible to boo, she is a natural and loved babyface, although her heel work has also been equally, if not more, impressive.
SmackDown 1000 is the perfect occasion for this to happen. This can take place in a contract signing segment. Becky can be cocky for a while and confidently proclaim how she will still be champion after Evolution. She, however, also talks about how much the title means to her and how hard she has worked to earn it back.
Charlotte, on the other hand, talks about her fantastic record with championships in the past. She also whines about how she came millimeters close to winning the title the previous week and at WWE Super Show-Down. Her tone is not of regret but rather complaint, frustration, and arrogance. She then looks Becky in the face and promises her that she will take her title back at Evolution.
She then hits Lynch with the microphone and continues to brutally assault her. Lynch tries to fight back but, Charlotte doesn't succumb. She powerbombs her through the announcers' table and a smirk comes on her face with the women's title in her hand.
Lynch is left hurt and commentators start to express their doubts over whether she will be a hundred percent for evolution after that. They become sympathetic towards Lynch and critical of Flair. This would be the ideal way to go with this rivalry for their marquee conclusive match at Evolution.
