Let me explain Match Day. When you finish medical school you’re a doctor, but you’re not really a doctor. You have to do more training to become the specific type of doctor you want to be. This training is called residency. Senior year of medical school is spent applying and hopefully interviewing at hospitals where you wish to do your residency. Medical Students rank their choices, and the residency programs rank their applicants. If two students are a couple, and are graduating and heading to residency at the same time, they can ask for a “couples match” to end up in the same hospital or city. My son and his girlfriend did this and are doing their residencies together in St. Louis. She is specializing in emergency medicine, and my son is specializing in radiology. In Murder is Medical, Cara and Evan are based on my son and his hopefully one day, fiancée. Susan wants the engagement to happen as much as I do!
