Joan of Arcadia

While helping Grace shop for a dress for the occasion, Joan is delighted to finally meet Grace's seemingly perfect mother, Sarah. However, when Sarah's drinking problem becomes evident, Joan begins to understand why Grace is so private – and why she's long been avoiding having her bat mitzvah. Meanwhile, Luke racks his brain to come up with a meaningful bat mitzvah gift for Grace. Additionally, Adam and Joan have different ways of coping with Judith's death. Will supports Lucy's less-than-legal means of trying to get one of Judith's friends to describe Judith's on-the-run killer, and Kevin's ex-girlfriend is deposed for the trial.
