Barb has found a new condo to live in and Matthew is moving in with Lucy, leaving Christine on her own (Ritchie is going away to camp for a week) for the first time. Christine feels abandoned but puts on a brave face; unfortunately, she locks herself out and gets her foot stuck in the toilet when she climbs in the bathroom window. Unable to free herself, she remembers a time when she was fiercely independent. When Richard and Barb find her, she's despondent, but her memory of her more independent days (and their teasing) inspire her to figure out how to get unstuck.

Matthew's relationship with Lucy is quickly tested when they move in together: her bizarre relationship with her dog and her obsession with how much space Matthew takes up makes them realize they can't be together. Matthew moves home and Christine is no longer alone.
