One shot.

Disclaimer: I don't own harry Potter and I found the idea for this one shot when I was scrolling through marauder memes on pinterest.

I, Remus Lupin, defence against the dark arts professor at Hogwarts, walked into my office, sat down and sighed. I'd been fighting with myself for the past goodness knows-how-long on whether to tell Headmaster Dumbledor my friends' biggest secrets and now I had come across two of my best friend's son with an object that we had created all those years ago. The Marauder's map. I remembered the time that we had spent creating it clearly. It had actually been Peter's idea first and everyone was surprised that he had come up with it. Poor Peter. He had suffered a horrible death at the hands of my very own boyfriend. I had trusted him with my life and he took James and Peter's. The horrible cowardly traitor. I was glad when I heard that he had escaped because I wanted a chance to murder him with my own two hands. I remember something about the creation of the map now. The hardest, but one of the most important spells that we had cast on it was one that made sure future troublemakers could open it. It imprinted our personalities onto the map, letting the map talk to people trying to open it. I could talk to Peter and James again. And maybe even the love of my life before he was ripped away from us and murdered by the cold man that now inhabits his body. I whipped the map from my pocket and said

"I, Remus Lupin, original and honorary marauder, command you to reveal your secrets." I smiled with tears in my eyes as Padfoot's familiar copperplate witing appeared.

"Mr Padfoot would like to say if you were my darling moony bamboony you would know how to open our greatest treasure"

"Mr Prongs agrees and would like to tell Mr Padfoot not to go all girly when talking about Mr Moony."

"Mr Moony would like to state that it isn't girly, its sweet and that there are only two Moonys and you aren't one of them."

"Mr Wormtail agrees with Prongs and the second thing that Mr Moony said. He would also like to make it known that he thinks anyone impersonating Mr Moony should get his facts right."

"But I am Moony and I can prove it. Ask me any question that is private and, Padfoot, make sure it wouldn't disgust James or Peter."

"Mr Padfoot agrees on the terms that when the impersonator gets the answer wrong, he tells us who he is and buggers off. What is your favourite failed attempt of James trying to ask Lily out?"

I closed my eyes remembering the good old days.

"I told you that just after Peter burst into the common room saying that Lily asked James out. While everyone was cheering, I leaned on you and said: I'm going to miss James asking Lily out, especially the time when he stayed up all night just to create a flying stage in the centre of the great hall and recruited the house elves from the kitchens to serenade him while he stood on the stage and asked Lily out. After he got two months of detention and was too scared to go within ten metres of Lily until his detentions were over."

"Mr Prongs would like to state that he was giving Lily her space, not being scared of her, and I swear she was about to say yes before Minnie came."

"Mr Padfoot would like to say that's total bull**** and she rolled her eyes and walked away before Minnie even got there."

"So do you believe me now, Pads."

"Yup"

"It's yes."

"No it isn't, it's yup but now I know that it's definitely you."

"So how old are you and what was the last prank you pulled?"

"Thirty-two and the last prank was one I helped some twins with anonymously. They were trying to make Lucious Malfoy's son only be able to eat old porridge because he said that muggleborns were stupid little m words that should only get to eat porridge and that he wondered why Albus was wasting his money on them."

"Does that mean we're a professor?"

"Yes. Albus hired me for defence against the dark arts earlier this year."

"Professor Lupin. It has a ring to it."

"Why did you feel lonely. I would never abandon you on purpose and James wouldn't either."

"Oi"

I ignored Peter and sighed but he deserved to know his own fate and it couldn't change anything anyway.

"I needed to talk to you again because – because you are a traitor where I am, James, Lily and Peter are dead because of you, Peter by your own hand. Before they died..." And I launched into a full explanation of what had happened from then to now.

"I can't believe I would do that."

"You didn't."

"How do you know Wormy?"

"Because I must have. Some Slytherins came up to me and bullied me into going to a meeting. I had no choice. After I betrayed you, Sirius must've known and killed me because of it. Maybe we were trying to trick the dark lord into going after Sirius, not me."

"Pettigrew, you aren't a Marauder or our friend or our brother. I don't even want to know you."

"I'm sorry."

"He's - he's gone."

"Enough with all the dramatics. Tell us more about Prongslet. And he got it from the Mini Marauders. They were awesome and they worked out the map really quickly. It's a shame. They were nice to talk to." But I sat in my seat barely registering the new message. After Peter confessed, I realised that it was obvious. How didn't I see it before. All this time I was blaming him when we could've spent it together. I had to fix this. I opened the map properly and looked on it and as they say, the rest is history.

Yes I wanted to make you cry. If I didn't please tell me and I will have another go. If I did please tell me anyway.
