It only takes a few minutes for the unconscious ensign to be hauled off, which is more than enough time for Khan to mentally catalog his own injuries. His ribs are broken - at least one has nicked a lung and punctured something more vital - he's hemorrhaging internally, fractured his left ulna, and easily has half a dozen cuts and burns.

At the doctor's offer, though, his expression shutters. "That won't be necessary," he says, shaking his head. The moment he steps into the Sickbay, any hope of hiding his identity is lost. "They will heal."

Which is the truth, if not the way a human might put it. Given time and rest - more than he has been getting - and Khan's injuries will vanish like they'd never existed at all. He won't even scar.
