Kevin Banks is a surgical resident who was up for the same job as April Kepner.
While entering the hotel where they would take their boards, April ran into Kevin Banks. She noticed that he was wearing a hat from Case Western Reserve and noted that she'd just been offered a job there. He was disappointed, as he'd been waiting to hear about a job.
Later that night, Kevin approached April at a bar. He implied that she only got the job because the man who hired her wanted to sleep with her. She attacked him. They fought until Richard came in and broke up the fight.
