Meanwhile, Mary and Eric can't see eye-to-eye on her relationship with Robbie, but they soon agree to compromise. When Mary informs Robbie of the plan, he tells her that it won't work between them. Fortunately for Mary, Robbie changes his mind after talking to Eric in the local grocery market. Also, Lucy gets into trouble after blowing off a Habitat for Humanity project to go on a date, and is caught. Meanwhile, Matt is consumed with depression due to Shana's upcoming move to New York.
