A New New York

In the Season 5 premiere, Sonja kicks things off with a party to mingle with Aviva, Carole and Heather. They all seem to hit it off. . .until Ramona arrives. And as they say, with new friends come new revelations -- in this case, Aviva learns that a couple of her "new" friends have had relations with her ex-husband. Meanwhile, Heather and Carole try to figure out who to trust and not. Picking up right where they left off, LuAnn is still annoyed with Ramona about the disparaging comments she made about LuAnn's parenting (from last season) and tries to discuss it with her at the party, but Ramona has no interest. Things get interesting as Sonja, Ramona, Heather, and Aviva head to the Hamptons for the weekend and once back in the city, LuAnn surprises the new ladies with a shocking story. The three new women agree to never become "mean girls."
