He had, in truth, been losing her for a very long time. The disease that was killing her was a creeping, cowardly thing, a sickness that ate away at her from the inside, slowly consuming the light within, so that her eyes grew a little less bright with each passing day, and her skin a little more pale.
And as she was stolen away from him, piece by piece, the boy became more and more afraid of finally losing her entirely. He wanted her to stay. He had no brothers and no sisters, and while he loved his father, it would be true to say that he loved his mother more. He could not bear to think of a life without her.
