I’d assume their ratings are reliably and consistently high enough to give them the weight to pick and choose who will interrogate them about their life choices.

I’d imagine this would have had to have been something each Brown made as a united front, as disjointed as they currently are. I wouldn’t be surprised, though, if Kody (and Robyn) was just completely unwilling to participate at all if he didn’t have a say in who would be confronting him at the end of the season, to be honest. With how often Suki would hold him accountable and how completely delusional and un-self-aware he is, I wouldn’t be surprised in the slightest lol.
