"Your mother died to save you. If there is one thing Voldemort cannot understand, it is love. He didn't realize that love as powerful as your mother's for you leaves its own mark. Not a scar, no visible sign...to have been loved so deeply, even though the person who loved us is gone, will give us some protection forever. It is in your very skin." ~Professor Dumbledore
I like everything about this. One, the lightning scar. It's actually a scar of lightning, and not just a red line. I also like that his hair is super messy, although I don't think he'd have it that long. Or maybe he would, in memory of Sirius. (I'm sorry, I made myself cry too.) He's just everything he should be according to the books.
