I kind of wish Joy didn't leave bc it seems like a win for MM. I hope she is not sick, but I really think something went down backstage. I think if she were sick she wouldn't have come in the first place... not show up and leave before air.
One clue, MM describes herself as a straight shooter and she airs her grievances like in Seinfeld's Festivus. Something happened. I hope Joy spills the beans.
