As far as Derek was concerned, his social skills were impeccable. People loved him and took pictures of him and listened to what he said, even if it sounded really retarded (which it usually did.) He watched her rock, his puzzled expression resembling a monkey's, before he drew slightly closer. He thought about trying to comfort her by patting her on the shoulder, but he was afraid that he might got snot or tears or something else gross on him, and so he settled for patting her on the head.
"John? Ummmm.... oh snap! Dead? Well... huh... oh! Oh no! Someone's dead? That's terrible!" It was so terrible that it even made Derek forget, momentarily, about his nail. "Someone needs to call an ambulance!"
