Hermione's friends, like Harry, would likely be very protective of her. They might try to keep the news from spreading too far and help Hermione in any way they can. As for Draco, his family's reaction could be complicated. They might see this as an opportunity to gain some sort of advantage over the Weasleys, or they might be more sympathetic to Hermione's situation depending on how Draco feels about her.
The Ministry of Magic could also get involved. There might be laws or regulations regarding single motherhood in the wizarding world that Hermione would have to deal with. And if Draco becomes involved with Hermione, there could be political implications as the Malfoys and the Weasleys have a long - standing feud. The wizarding media would surely have a field day, speculating and reporting on every little detail of Hermione's situation.
Hermione is a strong - willed character. She might focus on her unborn child first. She'll use her intelligence to ensure she has a stable living situation, perhaps getting a job or finding a safe place to stay. She may also start to rely on her friends like Ginny for emotional support.
Another scenario could be that Hermione decides to keep the pregnancy a secret from most people. She might try to handle it all on her own, while still dealing with her feelings for both Ron and the unexpected situation. This could lead to a lot of internal conflict and self - discovery for her as she tries to figure out what she really wants in life.
It could be due to a misunderstanding. Ron might misinterpret Hermione's relationship with Draco. He could think there's something going on between them, especially in fanfiction where the Dramione pairing is the end goal. So, in his jealousy or anger, he decides to leave Hermione while she's pregnant without really understanding the situation.
Ron would probably be shocked at first. He might stutter and not know what to say immediately. Then, a big grin would spread across his face as the news sinks in, and he'd pull Hermione into a tight embrace, telling her how happy he is.
In the fanfiction world regarding Ron leaving Hermione for Lavender, the reactions would vary. Fanfiction writers might take this idea and run with it in different directions. Some might focus on the emotional turmoil Hermione experiences, which could lead to some really angsty and deep stories. Others might explore the relationship between Ron and Lavender, trying to give it more depth and meaning than it had in the original. There could also be those who write fanfictions that are more satirical, making fun of the whole concept while still exploring the possible implications in a light - hearted way.
However, there could also be those who are glad she's leaving. Some pure - blood supremacists might see her as a threat to their traditional views. They might think that with her gone, they can push their archaic ideas more freely in the wizarding world.
Some might be shocked and feel betrayed. Harry is a hero to many, so his departure could leave them feeling abandoned. Others might understand his need for a break and respect his decision.
Another way she could react is by distancing herself completely. She would stop trying to be part of their group and start creating her own identity at Hogwarts. She might explore parts of the castle she's never been to before, find new study nooks, and interact with students she's never really talked to, all while trying to forget about Ron and Harry's cold treatment.
Well, there would be a huge uproar. Pure - blood supremacists would likely use this as an example of how the wizarding world was going to the dogs. The Hogwarts faculty would be divided. Those who knew Snape well might suspect there was more to the story, but those who only knew his past would condemn him. Hermione herself would face a great deal of ostracism. She might have to leave her job at the Ministry if the public outcry was too much. And her relationship with her friends could be severely strained as they struggle to come to terms with this unexpected and controversial situation.
Some might be in shock. After all, Harry has been such an important figure in the wizarding world for so long. His friends like Hermione and Ron would probably be very worried about him and try to find out where he went. The Ministry of Magic could be in a panic, fearing that without Harry, they'll be vulnerable to new threats.
