"Yes, thanks for that map, it is really nice. I figured out Moony first, I saw Professor Lupin’s reaction when he caught Harry with it. You lit up and after that essay I thought about the possibility. I later saw Harry’s patronus, a Stag and I remember hearing that it was just like his father. Then we met the big black dog and that was you," I look up at Sirius. "And Ron's rat was Wormtail, you both called him that. I knew the four of you were friends, it was too much of a coincidence. Moony is moon, logical. Prongs, because of the antlers, Wormtail is because he became a rat, but I never figured out why Padfoot," I end hoping he will explain it to me.
