I have wondered ever since whether I was a coward. Perhaps I was. Perhaps I wanted the boy to make the choice so that I would not have to make it again. Perhaps I could not bear to watch my mother die twice. Or perhaps I sent it because I had finally understood her. I don't know. That is the truth. I don't know.
What I do know is this. My mother once held me when I was too young to understand what it meant to be chosen. She looked at my face and decided that the life in front of her was worth more than the pain behind her. Then she spent years making that decision again, every morning and every hospital and every examination, every burned meal and bad cup of tea, every time she told me to go home, every time she checked the laboratory twice, every time she looked at me after a success and let me see that she was proud. And I spent those years believing that love meant never letting her go.
That was too small. Love was also the reason she was willing to go. It is the part I could not see in the cold room with my hand on her sleeve, and it is the part I hope the boy can hear.
I know where he is. I know the cold of that room, and the seal, and the small sound it will make. I know the rain outside, and the old kettle with its hole standing on the stove at home, and the blue mug, and the crossword with one word left to fill. I know what his mother will see when she looks at him: her son, the boy she kept, the doctor she raised, the person she loves more than herself. And I know what he wants. He wants to hold on. He wants to believe there is always another answer, that if he works hard enough and thinks fast enough and refuses to accept the loss, he can change what is happening. I wanted that too. I wanted it so badly that I helped build the world that followed.
Somewhere in the past a voice is about to speak out of a wall. It may come through clear. It may come in pieces. He may hear a plea or a command, or only his own name said back to him by a stranger who sounds like him. He will have one second, and his mother's sleeve under his hand, and his mother's face turned toward him, afraid of one thing only, which is what he will do next.
There is one question I could never answer. No equation solved it and no treatment cured it. It was still there when all the money was gone and the laboratory was empty and the world had gone quiet, when the chair across the table stayed empty and the only person left who could change anything was the boy I used to be.
He is standing in that cold room now. His mother is one step away. His hand is on her sleeve.
And he has to decide whether loving her means saving her, or letting her die.
Will he let her die?
