Bethenny is used to coming back from that summer break fresh off of a season of friendship and fun with Carole. In 2016, she shared Instagram photos of the co-stars’ trip to Chicago , a video from their shared radio appearance , and a sweet post for Carole’s birthday . The same cannot be said for the summer of 2017. And, that’s because Carole spent most of the season in Los Angeles helping her friend Cassandra Grey, a beauty website founder, deal with the death of her husband, as Carole explains during Wednesday’s reunion installment. That integral detail wasn’t mentioned throughout RHONY season 10, despite the fact that it puts Carole's tension with her former TV best friend in an entirely new light.
