Joan of Arcadia

Instead of venting her romantic woes, Joan throws her energy into spring cleaning, which proves more than just therapeutic when it leads to the discovery that somebody at school needs her help. Joan's relationship problems cause Luke to feel insecure about his future with Grace, but then she surprises him with an ultra-cool gift; Kevin considers moving into his own apartment, an idea that upsets Helen.

Adam needs Joan to be there for him as a friend, but she finds it difficult to forgive and forget the hurt he has caused her. Helen's in a similar, albeit far more serious, situation when the man who raped her 25 years ago attempts to meet with her and personally apologize before he dies of cancer. Meanwhile, Luke disapproves of Friedman's pot-smoking, that is, until he considers marijuana use from a scientific perspective.

Joan is seeing and talking to dead people, including her deceased friend Judith (Sprague Grayden), who tells Joan to prepare for a test. Joan's family and loved ones start to wonder whether the high-schooler is losing it again, but Helen is left to question her own sanity after she too has a ghostly encounter. Meanwhile, Ryan Hunter, the young man who saved Adam's life, is becoming a constant, uncomfortable presence.
