All of the main characters will be returning except for Emily and Damon. Chelsea Hobbs (Emily) became pregnant in real life, hence Emily's pregnance. Because of this, she declined the offer to return for season 3. Because of her decline, Damon's actor doesn't really have a main part (except for his friendship with Kaylee). Razr will not return either.Also, Alex will most likely not be returning either; we'll see in March, though!(:
