Frankie is arrested for an over-due library book and suspects Brick until she finds out it's Mike's book. Sue dislikes Reverend TimTom's new girlfriend, Reverend Tammy (Casey Wilson), but isn't sure how to tell him, and they break up but get back together after a flash of guilt. Meanwhile, Axl and Cassidy reunite during Spring Break. After a couple of days catching up and enjoying each other's company, Cassidy leaves Axl a somewhat abstract painting, saying he'll know what it means, and when Axl pieces together the meaning, it's really a breakup with Cassidy. So much for true love, Axl!
