Oh, so this is how he found out that he loved lily... I can see him missing all the clues and having to learn of his crush on her by means of the mirror. I wonder if he's realized that what he craves the most is a happy family. He's just expanding on it from your last drabble, first he wanted his parents and now her, all of them happy to be together. All of them proud of each other...
This is a wonderful addition to your last one. I enjoyed it immensely. :)
