    Professor Dumbledore looked at Harry thoughtfully, his bright blue eyes not quite twinkling. "Your mother died to save you. If there is one thing Voldemort cannot understand, it is love. He didn’t realise that love as powerful as your mother’s for you leaves its own mark. Not a scar, no visible sign..." With a sigh that was somehow not as sad as Harry would have expected, he continued. "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."
