Agent Scully is a foil for Mulder in this regard. As a medical doctor and natural skeptic, Scully approaches cases with complete detachment even when Mulder, despite his considerable training, loses his objectivity. She is partnered with Mulder initially so that she can debunk Mulder's nonconforming theories, often supplying logical, scientific explanations for the cases' apparently unexplainable phenomena. Although she is frequently able to offer scientific alternatives to Mulder's deductions, she is rarely able to refute them completely. Over the course of the series, she becomes increasingly dissatisfied with her own ability to approach the cases scientifically. After Mulder's abduction at the hands of aliens in the seventh season finale "Requiem", Scully becomes a "reluctant believer" who manages to explain the paranormal with science.
