A week after having an altercation with Roman, Stephanie decided to make it personal by involving Nikki confronting her backstage and forcing her in to defending her title in a gauntlet match 

It was a trick Nikki wouldn't be defending her title instead Stephanie would send out Samoa Joe who just so happens to be feuding with Roman

This pisses Roman off and he soon comes out saving Nikki and attacking Samoa Joe

Don't mess with Roman's loved ones
