Harry followed Albus’ advice and pitied the living.
Especially George, the boy who had a wide smile with an echo, once. A man cut from plural to singular. After Fred, he really was holey. He missed him to the point he felt sick. His heart hammered in agony whenever he thought of Fred. He was well and truly missed. And George was never the same. No one dared him to be the old George. Who George had been. He cut his hair short (to peach fuzz; he and Fred had always had the same style and the red and strands just reminded him, even if his entire family shared the trait) and he didn’t give a real smile for years. His lips would twitch, but that wide open mouthed smile from Hogwarts was absent. Laughing felt strange because he had always had Fred to chorus with him, and it too was something he did not do for a long time.
So, of course Harry pitied him. How could he not? Could you look at a man who lost half his soul and not do it?
