About[]
After J.D.'s patient died although he followed every correct procedure, J.D. was very frustrated so he asked Dr. Walch if there were any other factors with the patient that may have led to his death. Dr. Walch didn't seem too concerned and quipped back at J.D.. ("My Lucky Day")
Two years later, Dr. Walch helped Doug discover his hidden talents of determining the cause of death of patients, and from then on Doug became a pathologist. ("My Malpractical Decision")
