Doc asks Dr. Sarah Morales to marry him, and she happily says yes and tells him about a job interview she has in Philadelphia. Doc tries hard to be the understanding fiancée, but he doesn't want to leave New York and he's scared of ending being the "wife" in his relationship. Meanwhile, Carlos is hoping that Doc won't leave him, and of course shows that he cares by needling Doc about who wears the pants and making Doc feel even worse. Doc tries to help a homeless mother and son because the mother needs treatment for pneumonia and son has Asperger's Syndrome. When Sarah is offered the high-paying job in Philadelphia, Doc starts to plan to go with her, and then realizes that he can't, and Sarah can't be the wife that he needs. Sarah needs to take this job for her own career. They sadly break up even though they still love each other.
