Jim Walker is the father of Brad Walker.
History[]
Jim came into the hospital with his son, Brad, when Brad had severe, intermittent abdominal pain. When his tests were negative, Alex Karev and Arizona Robbins wanted to run an exploratory laparoscopy. Jim initially refused, believing that Brad was faking his pain, but when Alex told him that Brad could die if he had what they thought he did, his parents agreed.
Brad was moved to the ICU after surgery and his parents were angry that the laparoscopy hadn't shown anything. However, Brad started bleeding from his chest and had to be rushed into surgery. He had a ruptured aortic arch dissection which was the cause of his pain.
Brad's surgery was successful and his parents were told he was doing fine. However, they were still angry that the doctors hadn't caught the problem earlier. Alex Karev confronted him, saying that if they'd taken Brad home like they wanted, he would have died.
