Sean Murray, who plays Timothy McGee on NCIS, underwent a noticeable weight loss in the eighth season. Fans questioned if the show would address it. Sean revealed he had overhauled his eating habits for health reasons, shedding 25 pounds. The show did not formally discuss the transformation, as it was a personal journey for Sean. He clarified on Twitter that his weight loss was due to a strict organic diet and cutting out alcohol and sugar. This transformation paralleled McGee's evolution in the show, as he became more self-assured and balanced in his personal and professional life.
