Charlotte is not on the show. First time she's been left off a PPV since SummerSlam 2017
I wouldn't be surprised if they throw her into one of the Women's title matches anyway. Or she gets involved in one of them to set up a title match for the next PPV. And even if not, there's still Lacey, Alexa, and Corbin, so the point still stands.
The real question (and the only one I care about): Will the IIconics defend the titles? And, if they do, against who will they lose them?
Probably not. If Alexa wasn't challenging Bayley and was fully committed to the team with Nikki, I think they would be, but WWE gonna WWE. Vince has no fucks to give about the Kabuki Warriors and has probably forgotten they were ever a thing to begin with, so don't expect them to challenge. Mandy and Sonya are barely a proper tag team anymore and have become more of a 'solo star with henchman' deal, so you can safely dismiss them too.
If Alexa loses to Bayley then maybe Extreme Rules will finally see the first (and most likely the last) defence for the IIconics. Until then, the titles will continue being glorified jewellery.
