"Exactly, he was away, but he didn't disappear, not in a way that Dumbledore would worry. Remus is from '83 and he remembers Sirius. I remember Sirius and I'm from 2003. History doesn't seem to have changed and how is that possible if we're not there? If it's like some time turner in reverse, if we go back, there would be two versions of us and we could never meet with our other self, making going back irrelevant," he said, knowing that he was coming to terms with the fact that he couldn't go back, no matter how much he wanted to.
Harry laughed bitterly at the question. "Isn't that the million dollar question? I'm ... alive and still breathing, which is more that anyone expected me to be. The Dark Lord casts the killing curse twice on you and you're still breathing, you have to be all right."
He shook his head. "It's fine. It's not every day that your infant son becomes older than you in the blink of an eye. We've all had to deal with ... strange things happening." Like every single person that died when he was still a minor coming back to life younger than he was. "We're all expecting hexing to happen." He might be even looking forward to that. "As long as people arrive and no one gets hurt, we call it a win."
