#4 Stephanie McMahon interferes in the main event
This probably wouldn't be all that surprising, but since this match has had a lot of build up on Raw over the past few weeks and will now be given the main event spot at the first ever women's pay-per-view, it would be a shock if this match ended clean.
Reports suggest that this won't be a very long match since Nikki Bella needed her sister to help her beat down Rousey, to begin with, and the former UFC Champion will easily continue her undefeated streak in New York.
It wouldn't be much of a surprise if Brie Bella became involved in the match, but it would definitely be interesting if Stephanie McMahon was the one who either cost Rousey the match or forced a disqualification since it's unclear who will be challenging the Raw Women's Champion following Evolution.
Even more interesting would be if Rousey was being beaten down by a number of stars and her old friend Shayna Bazler made the save and this was then the way that The Queen of Spades was promoted to the main roster.
