 Tom starts dating Eddie s substitute pediatrician, Dr. Liz Park. Before things get too serious between the two of them, Liz tells Tom that she is going to Switzerland for three years to study. Although they are very attracted to each other, Switzerland is an obvious obstacle, but they decide to keep dating regardless until she leaves. But because of Tom and their time together, Liz decides not to go to Switzerland. However, after their date, Tom and Liz return back to the apartment to find that Eddie has developed a high fever, for which Liz, in her doctor role, treats. This act makes her realize that pediatric surgery, her chosen field of study in Switzerland, really is her true calling; she has to go.
