Darlene.....so awfully good - one of those characters you can't wait until.....(NO SPOILERS PLEASE)..

But one thing that really irritated me in Season 3, Episode 1 - there is no way her character would have joined a mommy group. None whatsoever. And it's really irritating when writers do this all for the sake of offering a sub-plot to the tale for mere amusement.
