I almost didn't come back to Hogwarts, because I was selfish. Because the prophecy was about me, I took everything personally, when this was all and remains to be bigger than me. What the war actually was, was the start of change. I've seen Hogwarts change for the better, and I've seen it change for the worse. I hope you remember that we are not our family members, and that we are not our houses once you leave these grounds.
