I really am retyping this in the Drafts app after I accidentally lost what I was working on freehand in the PI.FYI app. (It's too buggy at the moment for my taste.) 😑
WWE doesn't have the exactly moment on YouTube. So here's a description of what happened. I'll save the videos for later I had linked here and make them separate recs.
On the May 14, 2019 edition of SmackDown held in London at the O2 (later the venue for Money in the Bank 2023), Paige, Kairi, and Asuka step into the ring before their match with Mandy Rose and Sonya Deville. Paige introduces Kairi and Asuka as the Kabuki Warriors and says they are the future of the division. The IIconics, sitting ringside, cringe at the name.
Mandy and Sonya come out. They compare the above to the reveal of Prince Archie of Sussex (born a few days earlier). They talk about Money in the Bank, where only one of them can enter the women's ladder match. They say the future is not the Kabuki Warriors or the IIconics but themselves.
So in summary unless the writers were trying to time this whole segment around Prince Archie I don't know why this had to be a thing in London. Here's an official WWE photo for your trouble.
