St. Sebastian Hospital

Person	Pic	Notes
Dr. Jack Shephard main article		Jack Shephard is a doctor and leader-figure of the middle section. He has control issues and trouble dealing with situations that he cannot fix. However, these are also attributes that lend him the ability to function well in a crisis. When his father performed surgery under the influence of alcohol, causing the death of a young woman, Jack initially covered for his father by lying during the inquest. He later changed his statement after being informed that the woman was pregnant at the time of her death. When two patients arrived at St Sebastians following a car crash, Jack chose to treat his future wife, Sarah Shephard, forgoing the oppurtunity to treat the other patient, Shannon's father Adam Rutherford, who died shortly afterwards.
