Best Case Scenario
AJ Lee retains her title after botched interference from Nikki Bella, setting up an eventual split between the sisters.
Brie Bella cannot afford a clean loss to AJ Lee if there is any intent for her to continue to be a top contender to the Divas title. The crowd is already having a tough time relating to her as a babyface. Having her lose decisively to AJ will only hurt the audience's ability to buy into her as a threat to the Divas title.
The lack of reaction for Brie is a bit disappointing, however. Like her, her sister or Total Divas or not, she has improved her in-ring game by leaps and bounds and has had a few really good matches against AJ in recent weeks.
Speaking of recent weeks, there have been a few hints that Nikki may be becoming a bit jealous of her sister, who has received title shots and racked up big wins over that period of time. On more than one occasion, Nikki has jumped into the ring to celebrate with Brie in an attempt to get the spotlight on herself.
A split between the sisters would be interesting, if nothing else, and would give Brie an excuse for losing.
Worst Case Scenario
Brie Bella wins the Divas title solely to add a happy ending for the first season of WWE's Total Divas program.
If Brie Bella wins the Divas title Sunday night and the company has legitimate plans for her as champion, then that is fine.
If she wins just to hype Total Divas, it is a major mistake. AJ has been the most marketable, most over Diva on the roster for the last two years. To bring her title reign to a premature end just to benefit a reality show that has nothing to do with the WWE product on Monday and Friday nights would do her a great disservice.
