Snape awoke to see Harry's eyes, bright and alive. He sat up to see a thirteen year old Harry, bright and innocent, in his house in Spinner's End.
"Dad, you're up!" Snape couldn't find anything wrong with this statement; he felt as if this were completely normal. "I've been waiting ages. You knew I was getting home from studying with Hermione..."
And Severus Snape found nothing wrong with any of this, because this was the Heaven he got to live in for the rest of eternity; forever and always.
