A month has passed since Eric invited Marys ex-boyfriend to stay with the Camdens until he got on his feet. Robbie happily continues to act as a member of the household--- and its driving Annie crazy. Robbie is Erics latest project, Ruthies new best friend, recipient of Simons financial advice, and according to Mary, Lucys boyfriend. Hes even cooking and folding laundry (the wrong way!). Frustrated and emotionally strained, Annie starts to think nobody needs a mother anymore. Also, Matt also feels unneeded from the family due to Robbie and pays an unexpected visit to Heather and her new boyfriend.
