Levi has never slept well, but it's better with Petra. She is peace and comfort, and she brings him a contentment he has never known.
And the nights when he still can't sleep, she is with him. For them, the small hours of the night are filled not with sweet nothings, but their devotion to each other.
"If we survive …"
They murmur their dreams, promises to each other.
"A wedding under the sky."
"A small house to call home."
"Sunday dinners with your father, and spoiled children with unending laughter to disturb the peace."
He marvels at how in tune with him and loving she is, never leaving him alone in the darkness and the silence. He wonders if she will ever let him stay up alone and gaze at her until exhaustion finally claims him, or if the quiet times will always be ones of happiness with the soothing sound of her voice, the joining of hands, and the stroking of hair. He watches her, trying to find the dreams that will elicit a smile or soft laughter, so he knows she is never the first to drift into sleep.
Their happiness is still a secret they cannot share with the world, but they will get each other through the war, so he begins to allow "if" to give way to "when the war is over" in his thoughts.
But she doesn't survive. And really, neither does he.
