Doctor Lawrence Gordon is dead.
Officially, at least.
As Mr. Kramer says (said), dead men do not go home and apologise to their wives and daughters for missing dinner. Neither do they announce that there was a mix-up down at the station but everything should be back to normal in a couple of days (years), nor that Daddy has something important to say about appreciating life.
The truth is, Daddy now finds himself stitching Mark Hoffman's face back together. It's a step forward. Fixing people is so much more fulfilling than all that slicing and drilling (murder), even if they had no time to procure a general anaesthetic and Mark is staring at the ceiling with half his face numb, trying not to vomit.
"This little piggy went to market," sings Lawrence, in time with the flickering of the bulb.
The detective doesn't dare move his head, but glares and grunts as best he can.
"This little piggy stayed home."
Lawrence doesn't care for his new family very much; they are far too dysfunctional (dead) and keep him very busy. But he wants to be a good father for once in his life, whether Mark (Diana) knows it or not.
