...There is a Reaction

At her father's suggestion, a heartbroken Amy is determined to make the most of her senior year in the wake of Ephram returning from New York and telling her that piano has to be his number one priority. Andy contemplates telling Ephram about Madison's (Sarah Lancaster, who does not appear in the episode) pregnancy. Meanwhile, Rose naively agrees to help Bright find his true calling after she discovers that he hasn't enrolled for college classes and is in fact leading a life of total leisure. Also, Dr. Jake Hartman (Scott Wolf) creates a marketing blitz for his new practice that threatens to push Dr. Abbott over the edge. Lastly, Nina takes in her friends' teenage daughter, Hannah (Sarah Drew, "Radio"), and asks Ephram to take her under his wing.
