In a fanfic where Harry walks in on Sirius and Remus, how could this situation affect their relationship with Harry?

This incident could also introduce new storylines. Maybe Sirius tries to keep Harry and Draco apart, which then leads to a series of events where they have to find ways to be together or communicate secretly. Or perhaps Sirius' reaction causes other characters to get involved, expanding the scope of the fanfiction plot.

He might be initially shocked. But if they were just having a friendly chat or doing something normal, he would quickly recover and probably join in the conversation. Harry respects them both a great deal, so he'd be more curious than anything else.

It could potentially strain the relationship. If Sirius misinterprets the situation, it might create some tension. Harry and Hermione would feel like they need to explain themselves, and Sirius might be a bit standoffish until he gets the real story. For instance, if he thought they were hiding something from him, it could make things a bit rocky between them for a while.

In some fanfics, Snape might help by using his knowledge of the situation. He could provide crucial information that clears Harry's name. Maybe he has some insights into Sirius' situation or the events that led to Remus blaming Harry that others don't have, and he decides to share that information to set things right.

If Sirius and Remus were Harry's fathers in a fanfic, it would change a lot. For one, Harry would have two dads who are very different yet equally loving. Sirius being an Animagus and Remus a werewolf would expose Harry to a different side of the wizarding world from a young age. Also, their relationship would add a whole new layer of depth to Harry's character development as he navigates his own identity within this unique family structure.

Friendship is also a major theme. They share a unique friendship that is different from normal friendships. In these fanfics, it's often shown how they support each other through difficult times. For example, when Harry is facing problems at Hogwarts, Sirius and Remus are there to give him advice and stand by his side. And of course, the theme of magic and adventure is always present as they are part of the wizarding world and have to face various magical threats together.

Yes, there are such fanfics in the Harry Potter fandom. Some fans like to explore different relationship dynamics and create unique storylines where Sirius and Remus are Harry's fathers in a romantic relationship. These fanfics often play with the idea of an alternative family structure for Harry within the magical world.

In some fanfics, they might find out through a letter or a message. For example, Dumbledore could leave a mysterious letter that reveals Harry's existence and his connection to them. It's a simple yet effective way to start the story.

Sure. Fanfiction writers love to play with established characters and relationships. In a story where Harry is Remus and Sirius' son, we could see new magical abilities or inheritances coming into play. Maybe he would inherit some of Remus' werewolf - related magic in a different way or Sirius' skills in magic related to his family's heritage. It would also change the emotional dynamics, with a different kind of family support system for Harry.

Well, depending on the context of the fanfiction, Sirius could also be very understanding. If he knew that Harry and Hermione were just having a private conversation about important matters like their fight against Voldemort or schoolwork, he might just give them a knowing smile and say something like 'Carry on, then. Just making sure everything's all right.' He's a rather perceptive character, after all. And he trusts Harry a great deal, so he would likely give them the benefit of the doubt before assuming anything untoward.
