While in medical school, she carried on an affair with her married instructor, Dr. Daniel Waterston who may have been the "college boyfriend" mentioned in "Trust No 1". It is never indicated in the show whether or not the relationship became sexual. According to Anderson in the episode's audio commentary, Scully came very close to having an affair with the married Waterston but left before she could break up his marriage. The end of her relationship with Waterston came about following her decision to go into the FBI. After her entrance to the FBI's Academy at Quantico, Scully began a year-long relationship with her Academy instructor, Jack Willis, with whom she shared a birthday.
