Sirius could play multiple roles. Firstly, he could be a friend who listens to Hermione's rants and sorrows. Secondly, he might act as a protector, making sure Hermione doesn't do anything rash in her emotional state. And thirdly, he could be a catalyst for Hermione's growth. His presence could make Hermione realize that there are other aspects of life and relationships that she has been overlooking. His friendship could open up new opportunities for her, whether it's in terms of magical knowledge or personal development, all while she is dealing with the aftermath of Ron's cheating.
She might be heartbroken. Hermione is a strong - willed character, but being cheated on would surely shatter her. She could initially be in disbelief, given her trust in Ron. Then, she might become angry and start to distance herself from Ron, focusing more on her own studies or other relationships, like her friendship with Sirius.
There could be. Fanfiction is a vast and diverse world where authors can take the characters in all kinds of directions. But it's important to note that this isn't in line with the general perception of the characters' relationships in the official books. It might be an interesting exploration for some who like to see how different twists can change the story, but others might be put off by it.
She might be extremely hurt and angry. In such a situation, running to Sirius could be her way of seeking comfort and support from someone she trusts. She could be feeling betrayed and might have a hard time believing that Ron would do such a thing.
Hermione would probably be extremely hurt. She's a very loyal person, and to have Ron cheat on her would shatter her trust. She might become withdrawn, not wanting to talk to anyone at first, and just try to process the pain on her own. Then she decides to run to Lucius, perhaps because she feels she has nowhere else to turn, or she thinks Lucius can offer her some sort of solution or support.
Hermione may view Sirius as someone who has been through a lot in life. He has his own share of betrayals and hardships. So, she might think that he can empathize with her situation. Also, Sirius has always been a bit of an outsider in the wizarding world, and Hermione, with her Muggle - born status, might feel a connection to that. Their relationship could be based on mutual understanding of not always fitting in perfectly, which makes her run to him when Ron cheats.
One reason could be to create drama. Fanfiction writers often like to add a lot of angst and turmoil to the story. By having Ron cheat on Hermione, it can create a huge rift not only between them but also among their friends. Another reason might be to explore different character traits. Maybe showing a darker side of Ron that wasn't explored much in the original books.
In fanfiction, this kind of plot twist can be really interesting. It might be due to the author wanting to explore different character dynamics. Maybe Hermione realizes she has a stronger connection with Sirius in terms of his more adventurous spirit or his different life experiences compared to Ron.
I'm sure there are. Fanfiction is a vast world where all kinds of scenarios are explored. A 'Ron cheats on Hermione' fanfic might be written to show the vulnerability of their relationship or to introduce new plotlines. But it's not something that would be acceptable in the context of the original story. It can be an interesting read for those who like to see different interpretations of the characters, but it also might be a bit controversial among die - hard fans of the original relationship.
In many fanfics, their relationship develops through shared hardships during the search for Horcruxes. They rely on each other more and more, which deepens their emotional connection.
Well, in a fanfic, Hermione might start spending a lot of time with Sirius. Maybe they have deep conversations about magic that Ron can't really follow. For example, Sirius could be sharing some really advanced dark magic knowledge with Hermione that Ron doesn't understand. This could make Ron feel left out and jealous because he wants to be the one Hermione is so interested in. Also, Sirius is older and more experienced, which could make Ron feel inferior in Hermione's eyes.
