Christopher turned and saw us.

For half a second his face simply fell open — shock, pure and undisguised, the expression of a man watching the impossible happen, watching two people he had been certain were beyond waking sit up and look him in the eye.

For half a second I saw the real him, with nothing arranged over it.

And I will carry that half-second for the rest of my life, because it told me something I had spent our whole marriage not knowing.

In that unguarded instant, before the mask came down, there was no love in his face.
