Remus learns the truth
Alarm bells were going off in Remus's brain. His thoughts were chanting 'He Knows' over and over again and his mind was screaming at him to run away. Remus could not even panic in peace, as Harry had more explaining to do. "I'm sorry to freak you out like that, but I'm telling you this because I need your help. I also want to help you. In the future, a potion called wolfsbane was invented. It allows you to keep your mind while in wolf form, and you will not hurt anyone, not even yourself. In my original timeline, you did not have this option. Your best friends, James, Sirius, and Peter, became anamagi. They would help you through your transformations, which took place in a shack in Hogsmeade that was never built in this timeline. It didn't need to be, as you now have access to wolfsbane. You can stay in the headmasters office, or the hospital wing, or anywhere you want during the full moon." Harry pulled out the vials of wolfsbane. "If you don't believe me, try using it on Sunday the fifth. As you must know, that is the next full moon." Remus was so close to punching this kid for somehow knowing his secret, then lying to him and mocking him to get out of this situation. Before he could begin to punch him, however, Harry said, "I have veritaserum to prove that I am telling the truth, I am willing to make an unbreakable vow, and I have the memories of people from my timeline, including you if you want to view them." Remus was confused. Not even the dumbest person on earth would fall for a lie like that. He might not even be lying, he realized. 'May as well see if he is telling the truth,' Remus thought to himself.
"Prove it,"

"For the love of Merlin! That was an emotional rollercoaster!" exclaimed Remus. It has been hours of viewing memories and listening to Harry's story. Neville had joined them right before they started looking at memories. He had nearly given Remus a heart attack. Though none of them would probably ever admit it if questioned, they spent the majority of the night crying. 'Wow' was all Remus could say most of the time. Remus was willing to help Harry with his plan, and he knew what was at stake. He knew they had to get rid of Peter Pettigrew. He was surprisingly mature for an eleven year old. Sadly, they all had bigger issues than whether or not Remus could cope with the truth. "I'm exhausted. We got no sleep, and have class in two hours," Remus groaned. "Don't worry about it," Neville said, smirking, as he pulled out three midnight black pills. "Sleepless Slumber, invented by Fred and George Weasley," Harry said grinning. Remus was very shocked about the tragic story of the twins. He was even more shocked that they were considered rivals, imitators, and successors to his own pranking legacy. He was also handed proof of his supposed 'supreme mischief'. He was given the Marauder's Map as a gift from Neville and Harry. He was impressed at his own magical ability. Harry's only comment was 'better make a new one soon, preferably without the rat's name on it'
They each took a pill, and immediately felt like they had gotten 8 or 9 hours of sleep. "Brilliant," Remus said, grinning.
"You better be prepared for the day," Neville said to Remus. "We have a traitorous rodent to befriend."
