Because she's desperate for a storyline? I'm no great fan of Ashley and Michael, but as you say, the case has already been closed. Karen has nothing else going on, really. Her daughter isn't going to be the next Cardi B (or even the next Candi D), she can't continue grieving her parents indefinitely, the dodgy issue of where she really lives is something she'd like to downplay, and she wants to promote her fragrance as much as she can without talking about what her role in creating/financing La' Dame actually is. (And what's that completely superfluous apostrophe or accent mark doing there anyway? Both wrong.) So she gets up on her victim soapbox and equates grabbing someone's butt with full-on rape--similar, but hardly the same--and demands to have the case readjudicated to her satisfaction. I guess it's a shiny distraction for a minute or two. But she can't keep pivoting every time Ashley counters her ludicrous logic. Not forever anyway.
Apropos of nothing, I have those same chairs on my deck that they had at the resort. Mine aren't stool height and they aren't black, but they're the same design. I love them. I also loved Robyn's glittery bathing suit. Put a sequin on it and I'm there for it.
Re Michael, I meant to add: Gay, bi, or anywhere along whatever spectrum, he needs to keep his damn hands to himself. What the F is his problem? No gay man I've ever known has behaved like that. And none of them were on TV.
