Something About the 'Men' in Menstruation - S2.E4

Carly has a big job catering a party for the mayor and she's so busy that she doesn't notice Sarah is acting preoccupied herself before leaving for school. When Sarah arrives home, she is still acting a bit odd. Jack asks what's wrong and she tells him she got her first period that day. Jack, who had just been bragging to Will about having it all together while Carly is out of the house, is thrown for a loop and bumbles around trying to find the right thing to say and do. Stephanie shows up at the apartment and leads Sarah in some strange New Age-type ritual to commemorate the event. Jack calls Carly to tell her the news. Carly feels that she should go home to Sarah, despite the importance of her job.
