Podcast Guest?

I know they have a rule of no guests but when they switched to two days a week i vividly remember them saying they may do guests. They also said they had already recorded an episode with a guest that would air shortly but never did. I’m so curious who it was and why the episode never aired.
P.S. I am all for no guests i prefer their banter together, unless it’s a guest that they are both friends with like when they had Ciara.
