Mary coming back will be a nice bit of fan service and will definitely help get people back on side again. Definitely as a friend though with the option of full-time if the newbies bomb.
We definitely need 3 new full-timers in order to create a real distinction between the Jen Shah era and the future of the show. Mary Cosby and Angie Harrington as friends with the possibility of full-time depending on how filming goes with the newbies. Whitney seems to suggest it'll be a bumper sized cast which I think is the best move going forward. 100% should be taking tips from New Jersey.
She was cast as a friend in season one as well. Mary gives such good tv that I wouldn’t be surprised if she get upgraded again. All they have to do is point a camera at her and she gives material effortlessly.A friend-of role will be perfect for her. Definitely a step in the right direction and the fans will be ecstatic.
