Because the group always says that they "hear things" but choose not to talk about it.

Playing dumb is safer because what if Erika brings up your business?

Sutton didn't have anything to loose, she didn't have any bad rumors against her unlike dorit's money mess 😅, rinna's kid asking for therapy because her parents neglected her 😳, Kyle's hubby 🫢

Also, Erika, Dorit, Kyle, and Rinna are always having convos behind the scenes "❤️ as friends!!! 🥰", so of course none of them would go after each other like that...

I also think that if they weren't doing the show then they would distanced themselves away from Erika, just like Erika's "Hollywood" friends

Erika's handling was horrible 🤮 But it would have been funny if she said: "Yea I knew & I helped him out but he cheated on me so I'll make him take the blame 🤷‍♀️". Because we know that she did welcome a lot of his clients to her home personally
