Sara is a high school student that asked Charlie to the prom.
Sara was at Paddy's Pub when local high schoolers found out that they weren't carding. Charlie broke up a fight between a "drunk" boy and Sara. Later, she called and invited him to a house party, where she asked him and Mac to buy a keg for her friends. They stayed and partied, and she asked him to the prom. They did go to the prom and dance, but her original boyfriend came back and she left Charlie for him. ("Underage Drinking: A National Concern")
