Cormac Hayes

Cormac Hayes is the new head of pediatric surgery at Grey Sloan Memorial Hospital.

History
Cormac started his new job at Grey Sloan Memorial. He went to round on his first patient, Jamie Caldwell, and found that they'd already started. He asked that they wait for him in the future before rounding on his patients. He butted heads with Meredith when he insisted on examining her himself and came to the same conclusion Meredith had. They ordered a CT, which showed a mass in her back between two ribs. Meredith believed it was a gallstone that had escaped during a previous surgery, but Cormac thought it might be a malignant mass. Meredith didn't want to mention a possible malignancy to Jamie and her mother, but Cormac insisted on telling them. They did a biopsy, which showed that the mass was not malignant. Meredith decided to remove the mass to see what it was. Cormac tried to object, but Meredith said it was her house and he was just a guest. The mass turned out to be exactly what Meredith predicted, impressing Cormac. He later saw her when he was leaving the hospital and told her that while he understood it was her house, someone had given him a key, so they needed to learn to live together. He explained that he told Jamie and her mother about the possible malignancy because his wife's doctors weren't transparent with him when she was dying. ("Let's All Go to the Bar")
