#2. Alexa Bliss's involvement in the storyline

The WWE Universe lost its mind when The Fiend attacked Alexa Bliss in the closing moments of SmackDown and the move has to led to a myriad theories on what this could mean for SummerSlam. Furthermore, it has raised an important question of whether Bliss is actually Sister Abigail or not.
Braun Strowman has been involved storyline-wise with Alexa Bliss in the past, and there are a lot of places the company could go with this at SummerSlam. In fact, if Bliss were to reappear as Sister Abigail during a title match between Strowman and The Fiend, it could be WWE's way of costing him in the title.
Not only would it protect Strowman in defeat and get the title on The Fiend, it would probably be one of the most meaningful additions to the character's lore in awhile. Of course Strowman has to take the loss and have the title taken off him in this scenario at SummerSlam.
