Sweeps

Although Robbie is just as nervous as everyone else, his presence in the house during Marys weekend stay causes a great deal of concern among the Camdens. Matt and Lucy are especially suspicious after Lucy accidently finds a condom in a misplaced wallet. Imagine their surprise when they learn that the provocative prophylactic belongs to Simon--- who just so happens to be spending the evening with his new lady friend, Sasha.
