When Dr. Abbott's dementia-plagued, elderly godfather (guest star Luke Askew) confesses to a murder that took place 30 years ago and reveals that Abbott's father was his accomplice, Abbott and Dr. Brown join the investigation in an attempt to find out what really happened and clear the men's names. Meanwhile, Ephram can't seem to keep Amy (Emily VanCamp) far from his thoughts, causing major problems in his burgeoning relationship with Laynie (Nora Zehetner). Dr. Brown butts heads with Ephram's new piano teacher (guest star Ian Vogt) over what is best for Ephram.
