In the fanfiction where Sirius is watching Harry doing a ritual, what is Sirius's likely reaction?

Well, it could have all sorts of consequences. Maybe the ritual is meant to unlock some hidden power within Harry. If it goes wrong, it might put Harry in danger, like attracting dark forces. Or perhaps it's a ritual to communicate with the past, and if not done properly, it could mess with time and space.

One reason could be Harry's impulsiveness. Harry often jumps into dangerous situations without thinking, and Sirius, being his godfather and having a protective nature, would shout at him to make him realize the risks. For instance, if Harry decides to go after a Death Eater alone.

Yes, there are some fanfictions with this concept. In the Harry Potter fandom, writers often explore alternative family relationships through fanfics. This particular idea of Sirius being Harry's dad can lead to some interesting storylines, like re - imagining how Harry's upbringing would have been different if Sirius had been his father from the start.

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.

Definitely Hagrid. Hagrid has always been around Hogwarts and has a connection to the students. Sirius could interact with Hagrid if he goes back in time. Maybe Hagrid could help Sirius in some way, like providing shelter or information. And Bellatrix Lestrange could also be in the picture. Since she is part of the Black family, Sirius might have to deal with her in the past, either to try to change her or to stop her from doing something evil.

Neville Longbottom could also play a more prominent role. Neville has his own growth arc in the series, and after Sirius's death, he could bond more with Harry over their shared experiences of loss. They could support each other in their fight against the Dark Arts. And perhaps some of the Death Eaters who were involved in Sirius's death could be main characters from the antagonist side, as Harry tries to track them down and bring them to justice.

It's also likely that they go to Romania. Given Sirius' knowledge of the wizarding world, he might know of a safe haven there. In Romania, they could be around dragons and learn about dragon - related magic. Harry would surely be fascinated by the dragons and it could be a place where he can grow stronger in a different kind of magical environment.

Maybe Sirius left his possessions to Harry. His beloved motorcycle could be bequeathed to Harry, as it was something very special to him and also had a connection to Harry's escape from the Dursleys in the past.
