Marcus King

Marcus King is an old classmate of Miranda Bailey who came into the hospital after being in a bus crash.

High School
He went to the same high school as Miranda Bailey. While they were there, she had a crush on him and he used this to get her to do all his homework for him. At one point, he implied that he'd take her to Homecoming, but didn't end up inviting her.

Bus Crash
Marcus was taking a group of high schoolers on a tour of colleges when the bus they were in slid down an embankment. He was taken to the ER, where his only complaint was cuts on his arm. Bailey stitched up his arm, but then George O'Malley asked her to listen to his heart. She did and then called for a cardio consult.

Erica Hahn listened to his heart and heard atrial fibrillation and prescribed blood thinners and an outpatient workup because he wasn't symptomatic. However, he later had a cardiac episode. He had a ventricular septal defect. They took him into surgery to repair the defect.

After his surgery, he thanked Bailey, saying he wouldn't have made it through the day without her.

Friendships
When he was in high school, Miranda Bailey was his tutor. Because she had a serious crush on him, she ended up doing most of his homework for him. When he came into the hospital as an adult, he talked her into doing all his paperwork for him.

Career
He works at a high school. Part of his job involved taking a set of students on a tour of colleges.
