Harry would probably be very supportive. He knows what it's like to grow up without parents, and he would see Hermione's decision as a very kind and noble one. He might offer to help in any way he can, like teaching the child some of his own skills in magic or defense against the dark arts.
Hermione's other friends from Hogwarts, like Ginny, would likely be excited for her. Ginny, being a mother herself in the future, could offer Hermione advice on raising a child. Neville might also be very positive, as he has always respected Hermione. He could help by providing some plants or herbs from his greenhouse that could be useful for the child's health or for Hermione to use in her magic while taking care of the child.
The other Gryffindors would likely be divided. Some would be outraged, thinking that Hermione has betrayed the house by getting involved with a Slytherin, especially Draco Malfoy. However, others might be more understanding and see that love can cross house boundaries. In Slytherin, Draco's friends would also have mixed reactions. Some would be proud that Draco has managed to get Hermione pregnant, seeing it as a sort of conquest, while others might worry about the implications for their standing in the wizarding world.
One possible storyline could be that Hermione, having witnessed the hardships of war and the many orphaned children, decides to adopt a child. She might choose a child who shows magical potential but has been overlooked in the post - war chaos. The story could then focus on her struggles and joys of raising the child while also dealing with her own career and the expectations of the wizarding world.
Harry would likely be furious. He'd immediately start planning to rescue Hermione. He might try to gather evidence of the dark magic used to enslave her and take it to the teachers. Ron, on the other hand, would be impulsive. He'd probably want to storm into the Slytherin common room right away to free Hermione, without much of a plan.
Harry would probably be initially cautious. He has a long - standing feud with the Malfoys. But knowing Hermione, he would gradually come around and support her. He might even see it as a chance to break the cycle of hatred between the families. Ron, on the other hand, would be more vocal in his doubts. He would question Hermione's decision, but in the end, he would also be there for her, especially if he saw how much the baby needed care.
Hermione's friends from the Ministry of Magic or other magical organizations would also react. Those who respect Hermione for her intelligence and contributions would be supportive. They might offer her more flexible work arrangements so she can take care of the baby. However, there might be some who are envious or judgmental. But overall, Hermione's true friends would surround her and the baby with love and protection.
Harry and Ron would probably be very worried. They'd rush to her side immediately. Harry might use his skills to try and find a way to heal her quickly, while Ron would be freaking out a bit but also trying to be helpful.
She might initially be in shock. Hermione is used to relying on her friends, so the betrayal would be a huge blow. She could then become angry and start to isolate herself. In some fanfictions, she might try to figure out why they did it on her own, using her intelligence to uncover the truth.
She might be initially shocked. But being Hermione, she would quickly gather her wits and start planning. She could use her vast knowledge of magic to find her way or to signal her friends.
Hermione could also get angry. She's a strong - willed character. So, instead of just accepting the situation quietly, she might confront her friends and demand to know why they are ignoring her. This could lead to a big argument or a revelation about what's really going on.
She might withdraw. Hermione could become quiet and start spending more time alone, like going to the library even more often than usual. This is her way of protecting herself from further hurt.
