(really) short, but the idea popped in my head and I had to write it down.
The first thing he noticed was the light – for someone who had spent most of his life in the darkness, all that brightness was almost blinding. All the other senses told him he was in nothing but a room full of nothingness, but his eyes betrayed him: the man saw himself standing in a garden, under the canopy of a big, old tree, with grass under his naked feet and wind blowing his dark hair. The place, he soon came to realize, was extremely familiar.
And so was the woman sharing it with him.
Even after all these years, the sight of her still made his heart skip a beat. She was the same as he remembered: the same auburn hair, the same green eyes full of joy, the same smile able to make icebergs melt. He had many questions – about where he was, what all that meant, what should he do next – but all of them seemed irrelevant compared to her.
His lips moved, without making a sound. What could he say? Ask for forgiveness? Tell her how much he loved her? There weren't enough words to express what he felt, what he was felling. Somehow, by the look in her face, he knew they wouldn't be necessary, either.
She reached out for him, interlacing their fingers; her hand was soft, like he remembered, as soft as pure silk, driving him forward, to the next big step. The memories of what had happened minutes before – the Dark Lord, the snake and the boy, with the same green eyes she had – started to fade away, together with the room itself, as the white light engulfed both of them.
And beside his Lily, Severus Snape found peace.
