Harry Potter All Over Again

I caught the Boy-Who-Lived twice by now by the shoulders, my forehead against his.
"You have to go back!" I told him. "Everything is falling apart around us. Tom was never the bad guy! I can't believe we all followed Dumbledore so blindly...
"Go back and do what?" the famous boy asked me, grabbing at my arms as the world started spinning out of the control around us. "What is going on!?"
"I'm sending you back, Harry, you have to change everything. Remember, Tom is the good guy, and it's alright to be a Slytherin."
A few seconds later, Harry Potter disappeared in oblivion. I could only hope I had succeeded. There was so much I wanted to tell him. It didn't matter, I left a fail-safe with him, and at least one of those things should reach either or both of us in the past, offering us a chance to do it all over again. the right way this time. There wasn't anything I could do anymore, anyway. With Potter I had sent my magic, it being imprinted of all the memories, all the future I didn't wish for anyone.
I took a deep breath, looking around one last time. After the war, things had started going so well. But the chaos and destruction in front of me showed me how wrong we were to believe blindly all we were told. Perhaps he wouldn't even have to side, after all. He was the Boy-Who-Lived, and for that many would follow him to the End of the World, thought that was exactly what we aimed to avoid. Yes, Tom's methods were perhaps too harsh in getting where we has to go, and that had pushed most to blindly side with the Light regardless of their magical affinities sometimes even. But Harry held the power to change everything. I had to believe it.
But for me, for this world, this timeline, nothing could be done. I would never know the new timeline, the ripples and effects, if this was all in vain. Perhaps, if things hadn't been so bad here, my other self would have found a way to communicate with me through my magic and I would've known. None of us would live to find out.
