We will continue to follow Whitney and some other girls of the season 2 but for the moment I do not know who.
It would seem that season 3 will have some surprises with, in particular, the appearance of celebrities as guests.
The casting for this new season will start soon, creator/executive producer Ilene Chaiken said that she is "excited and gratified to be picking up the stories of our most beloved Season 2 cast members at some truly major and life-altering junctures, and we think it's time to throw down and invite the women of New York to join in and demonstrate the claims they've lobbed at us these past few years … that New York's women have something more to say about lesbian life, something that isn't being said by our Los Angeles ladies. Bring it on, Brooklyn!"
This season 3 will propose 9 episodes and will start at the beginning of next year.
