Harry's POV
"Tell us, what happened on the night of Halloween 1981?"
This is it, this would be, until he will manage to get the story from Voldemort's perspective, the fullest version of what happened on that night.
"I was at home, waiting to be called as I took another glass of icevotka, trying to calm my nerves as I knew this day would be the last one I would live as I did till now, that no matter if I succeed or fail, this was my chance to make a difference in the world." Pettigrew started telling his story. "And then I was called, the pain that dammed tattoo shot through my hand was horrific, almost as much as a Cruciatus from the dark lord himself, something he made me feel once or twice as I failed to show results, and understanding that once again made me rethink my choice, about choosing to do it and having to deal with the guy who won't only kill whoever stood in his way, not only torture them, but would make sure his followers would experience it too, and on a regular basis.
But I had no choice, so drowning my third glass of icevotka, I apparited to the Lastrange manor, where the dark lord spent the night.
"Hello wormtail, how nice of you to join us." The dark lord said, making me wince as I once again regretted telling them about the nickname, as they took a friendly joke and made it an insult.
Putting a nervous smile on my face I said "what do you need me for, my lord?"
"My patience is running low, I told you that today was your last chance, did you, or did you not found where the Potters stay?"
"I, I did my lord." I said, giving him the piece of paper that was prepared beforehand with the address of James and Lily."
"Wait!" Harry stopped him there, noticing something weird. "Why didn't you tell him about the address yourself? Why give it in a piece of paper?"
"I couldn't, wasn't the secret keeper."
"You weren't? Then who was?"
"Dumbledore of course, whose hands would you put the secret that safe guard your life in except the one who scares Voldemort the most?"
"And you got the coordinates of the house from Dumbledore who knew who you are going to give them to?"
"Of course, all of it was his plan to finish the war once and for all, he was the reason I became a spy for both sides before Snape came in and stole my job."
"You were a double agent?"
"Yes, no one would have suspected me having the courage to spy on the dark lord, not even me, but never forget my house, I am a Gryffindor thorough and thorough. So when the headmaster himself, Dumbledore, asked me at the beginning of my final year at Hogwarts to help the war effort and infiltrate the Death Eaters, I agreed and managed, little by little, throughout the year, to convince a few of the sympathizers that I agree with their opinions, this making me the official spy in both the Death Eaters and in the Order of the Phoenix."
That explained so many things, why Peter betrayed his friends, how Dumbledore didn't seem to know about any of that while in a war with the abilities of a Legilimen, nor with Snape as a spy, yet didn't seem surprised when it was revealed in the original story.
It also meant one thing clearly: Dumbledore isn't the that 'good grandfather' who cares about his students even after their graduation as he portrayed in the books until the almost end of the fifth, as long as you don't think too deeply about them, the best situation is that he is the greater good man, something Harry seriously doubted, with the worst is that this so called war of light and darkness is in fact a war between two evil guys with different philosophies about the way to control the world playing a gigantic chess game with all magical people as their game pieces.
"Continue your tale about that Halloween night." He said, wanting to know what exactly happened.
"As I gave him the piece of paper I gave a request Dumbledore hasn't told me to ask, something I have never done before but felt the need to do it for the chance to save my friends.
"My lord," I said, letting my fear out as much as possible, hoping the rumors of his ability to small fear and his love for it put him on a good mood. "Would you mind instead of killing James and Lilly Potter, stun them so I can do it myself? I really want them dead on my feet!" It was my last chance to make sure they survive, Dumbledore already told me the prophecy made sure at least one of the children would survive and that the dark lord would die, this was my chance to also save my friends.
I don't know why, maybe the rumors were true, maybe knowing this night is the night he destroy the prophecy the headmaster told me about, maybe it was part of fate just like Marcus surviving the night or maybe it was the thought of how fun it would be to watch the Potters realize their friend betrayed them and caused the death of not only them but their children, but it worked.
"Never say Lord Voldemort doesn't repay for hard work."
"Thank you, my lord, thank you." I bowed before appariting to the street near the house and changed to my rat form before hiding near the entry door to watch and see if there was something I can do to help, as while I am not that good in wand subjects, I was the second best in potions in my year, just after Snape, and you don't know when a potion might be needed to save someone.
As the dark lord showed up my nerves went through the roof, as he obliterated the front door I cried, knowing that whether or not my friends would survive, they would never forgive me, but I did it for the entire wizarding world.
The flash of red light before the sound of James yelling curses stoped made a relief shoot through my body as I ran toward him just to see he was only unconscious, a red light followed by a scream of Avada Kedavra and a green light made me transform back to my human form as I moved upstairs, as quietly as I could, hoping I could see my hard work payed off, and my godson survives, yet I hearing another Avada Kedavra made me rush up instead, thinking that if non of it worked I would better die as I caused the death of two babies for no reason, yet the screech that came right after it convinced me I managed to do it, I saved the world!
Rushing even faster upstairs, I managed to change into a rat and hide in the corner just in time to avoid being seen by some sort of smoke with a face that looked like the dark lord before it leaved.
Seeing the body of the dark lord disappeared, with only his wand where it should have been, I knew the dark lord is still alive yet in his smoke state.
Making sure Lilly is alive I then turned to the twins,
One of the twins was crying with blood siping out of his head and I immediately used some of the Dittany's essence I had on hand, before turning to the other who seemed to be as unconscious as his parents, though was also bleeding from the forehead, using the rest of my Dittany's essence I made sure the blood stopped gashing from both of the children's head before using a two street mirror to call the headmaster."
At that point both Harry and Luna were shocked, both he and Marcus were hit with the killing curse and survived? Was the prophecy different in this world? Unwilling to to interrupt the story again, Harry saw Luna was about to speak but with a quick look in her direction he made sure there would be no interruptions
"Professor," I said "it worked, they all survived."
"They all survived? All of them?" The professor's tone was of a surprised man, yet had another sound I couldn't recognize.
"Yes, all of them, I managed to convince the dark lord to spare them for the time."
"What about Voldemort? Is he truly dead? Who is the one who defeated him? Who did Voldemort marked?"
"N-No, I don't think he is dead, I saw some kind of a spirit like smoke leaves the room after he casted his second Avada Kedavra, and I don't know which one did he mark as both boys are bleeding from their forehead, the only difference is that one of them is unconscious and the other is crying."
"That is most troubling," the older man said in a grave voice. "Voldemort's survival means only one part of the prophecy was fulfilled, and we have to know who is the chosen one so we can make sure he is prepared, but for now, you must disappear, hide, I will help you make everybody think you are dead, until the day Voldemort returns and you can serve the light again."
"But... they would think of me as a traitor!"
"No, my child, I would make sure everybody believes you to be a hero, no matter what."
After finishing the conversation I ran away, and for three days I lived in muggle London, trying to fit in until Dumbledore made contact with me again, telling me everyone think I'm dead by the hands of Sirius and that he is waiting for a trial, before telling me he prepared a home for me as a pet rat for the Weasley family after telling Arthur pet rats were the muggle number one animals."
Harry felt all the pieces come together, Dumbledore probably changed the Potters memory of the secret keeper to Sirius, and made sure the prophecy would happen, he was also the one who made sure wormtail would be the pet of the Weasley family, the only two things he wasn't sure about are how could both him and Marcus survive, something he can't get an answer from the rat animagus and another thing, but just as he was about to ask it, Luna beat him to it.
"Why did you let Sirius go to Azkaban? Isn't he your friend?"
"Sirius? No, he is the guy hanged with my friends in school forcing me to hang with him, he is the guy who made fan of me at school all the time for being with less talented then him and having to work twice as hard for the same results. But I would have kept considering him a friend if he didn't almost made my best friend Remus go to kill someone and either go to Azkaban or be put to death for a prank. No, Remus, who helped me and I him, who was scared to hurt someone so much that he hurt himself, is my friend, James, who saved Remus and even Snape for nothing more then to help a friend, who understood boundaries, who spent more time with me then he needed to practice the animagus transformation so I wouldn't be the only one in the group in the castle on a full moon, is my friend.
Sirius is someone who tried to kill another person for laughs, I consider him being in Azkaban a fitting punishment."
Both me and Luna raised our eyebrows at this rant, it felt like he waited for that speech for a really long time.
"Well, I think that is all, do you have any more questions Luna?"
"No Harry, I'm good."
"Well then..." I said as I administered the antidote for the truth serum and raised my wand in the most unexpected person in this world that seemed more and more different from the books I have in my mind.
"Obliviate"
