I'm just speculating: one thing that's happened for Kay is that she's been publicly exposed as part of this thing. We speculate sometimes that one of Roth's motives is to claw at Michael's public image, and reduce his support in the legitimate world. Kay just received a big dose of that herself by sitting behind Michael on TV, and inside she may be absolutely furious that she can't go to Tahoe social functions anymore without people laughing at her.
