You were a medic at the survey corps, whom just came back from mission. The captain of the corpse, Levi Ackerman got injured on the mission. He has a huge cut across his chest, and is refusing to get tended because of his pride and ego

The other medics tried talking to him, reason with him, and convinced him to let himself be tended, but he wouldn't budge. That until you got fed up, grabbed him by the ear, and dragged him into your office, so you can take a look at him
