Somebody rushes past Derek and accidentally bumps into him. Their papers all fall to the floor. Derek, however, manages to catch them before they too fall to the floor. After a brief apology on their part and the Derek helping them gather their charts he speaks up. He doesn’t recognize them so he introduces himself -with a bright smile of course. “No worries. I’m Derek Shepard, head of Neurosurgery. And you?” He holds out his hand in greeting.
