Augusto Odone: You see, Michaela, it's as though he is trapped down in some dark cave. Because he's lost so much myelin, he can't find his way out. Now, we know his simple functions are intact. He breathes, he swallows, his heart beats. And from the outside world, he receives sensation. A touch, pain, cold. And here are the primal feelings. Fear, hunger, desire. While up here in the neocortex, the higher brain, locked here, are his reasoning, imagination, memory. The things that make us each ourselves. So how does he reach us? When a simple swallow is such a huge task? To find... To find the way, the path from his mind to the outside world is like willing himself through a brick wall. Michaela... Do you ever think that - maybe all this struggle, -it may have been for somebody else's kid? Michaela Odone: Yes. But I promised... I promised him - his world would never be silent. - He would never be alone.
