Well, James would first be in disbelief. Once he realizes it's true, his protective instincts would kick in big time. He'd become like a guard dog for Sirius. Remus, with his gentle nature, would encourage Sirius to talk about his feelings. He'd know that bottling it up would only make things worse. As for Peter, he'd be a bit clumsy in his support but still try. He might bring Sirius little things like his favorite snacks to cheer him up. All in all, the Marauders would form a stronger bond around Sirius to help him through this difficult discovery.
They are likely to be horrified. James, for example, would probably be extremely angry that his friend had to endure such a thing. He might immediately vow to protect Sirius from any further harm. Remus, being more empathetic, would be there to comfort Sirius and offer his support in a more quiet and understanding way. Peter, though not as strong - willed as the others, would still be shocked and follow the lead of James and Remus in trying to make Sirius feel better.
The Marauders would be outraged. James would want to seek revenge on those who abused Sirius. He's the kind of friend who won't let such an injustice go unpunished. Remus, on the other hand, would use his own experiences of being an outcast to relate to Sirius. He'd be a shoulder for Sirius to cry on and would try to help him heal emotionally. Peter would be in awe of Sirius' strength in surviving the abuse and would try his best to be a good friend in his own way.
They would be shocked and angry. James might immediately want to confront Sirius' family. Remus would be empathetic and try to comfort Sirius. Peter, though a bit cowardly, would also show concern.
One common theme is friendship and loyalty. The Marauders' unwavering support for Sirius showcases the strength of their bond. Another theme could be healing. Sirius has to go through a process of emotional healing, and the fanfiction might explore how he does that with the help of his friends. Also, there might be a theme of justice, especially if the abuser is still around or if there are people who need to be held accountable for what happened to Sirius.
One possible plot development could be that they try to hide Sirius from his family. Another is that they report the abuse to the authorities at Hogwarts.
Well, Sirius could get really flustered. It could lead to some comical or tense moments depending on the context of the fanfiction. The howler might reveal something he doesn't want others to know.
The marauders' reaction would be quite complex. They might feel a sense of nostalgia as they read about the world they once knew, but through a different lens in the fanfiction. They could also be a bit critical. If the fanfiction didn't seem to respect the essence of the original story, they might be quick to point it out. However, if it was well - written and added new depth to the story, they could end up really enjoying it and even discussing it at length among themselves.
Maybe they overhear a secret conversation between teachers or magical creatures that give them clues. Or it could be that they discover a hidden room filled with evidence about the Marauders.
Yes, they might. Fanfiction can be a great source of entertainment and alternative storylines. Marauders, being characters full of curiosity, could potentially be interested in exploring different takes on their own adventures or the wizarding world in general through fanfiction.
One common theme is loyalty. Sirius is extremely loyal to his friends, the Marauders. So many fanfictions explore this loyalty, like how he stands by them through thick and thin. Another theme is family. His difficult relationship with his family, especially his pure - blood supremacist relatives, is often delved into. For example, stories might show his struggle to break free from their expectations.
They might be very amused. The marauders are known for their sense of humor and the 'A Very Potter Musical' fanfiction is often full of comical and over - the - top elements. So they'd probably have a good laugh at the silly situations and the creative liberties the fanfic takes.
Healing is also a major theme. The sister goes through a process of recovering from the psychological and physical wounds of abuse. This can involve making new friends, finding new interests, and learning to trust again, which is often explored in great detail in these fanfictions.
