Sherlock and John sat and waited. They knew Hamish would not wake the next morning. Suddenly, Sherlock looked up.
"If he should die tonight, every single part of me will die with him."
John stood up and went to him. He hugged Sherlock and whispered, "If he should die tonight, then we shall all die together."
They stayed there a long time, listening to Hamish's heart monitor beat every couple of seconds. It slowed a bit and suddenly it stopped. There was a single tone going on and on, never ending. John buried his face in Sherlock's shoulder and sobbed until he couldn't anymore, clutching his shirt in his fist.
The doctors all rushed in at one, but they hardly noticed. All they cared about was each other and their son. Everything stopped. The sounds of monitors and doctors and nurses faded, as if they were under water. They held each other tightly as if one of them would just drift away. As if one of them would fade into nothingness and they would be left to face the world alone. And that terrified them the most.
So they stood together, crying and whispering with shaking breaths, each secretly wanting to die. To just lay down, shut his eyes… and fade.
"What do I care for life when you are dead?"
