"Sirius holds so much guilt and anger over their deaths and it was getting better with time, but this is the first Halloween he’s spent with Harry, and all those feelings came back tenfold. Lily and James died seventeen years ago, and he knows that, but there’s a finality in seeing their graves. I’ve visited them for years, ever since they died, but for Sirius this was the first time, and his temper just boiled over. When we were leaving Godric’s Hollow, he said some shitty things and I know he didn’t mean them, but I took the bait anyway and we did it all right in front of Harry."
