Some of their friends might think it's a strange situation. Luna could see it as a very interesting and magical development, believing that there must be some deeper, cosmic reason for it. Seamus and Dean might be a bit skeptical at first but would warm up to the idea as they see Harry and Hermione making the best of the situation. The Weasley family as a whole would probably have a mix of reactions, from Molly's motherly concern to Fred and George's attempts to find the humor in it.
Over time, if she couldn't immediately escape, Hermione would try to influence the Death Eater. She would use her knowledge and strong moral compass to show him the error of his ways. She might start by having debates with him about the Dark Arts and the ideology of the Death Eaters, hoping to make him see the light.
Harry would most likely be horrified. He has always seen Lucius as an enemy. He might start plotting ways to escape this forced marriage. He would also be worried about what this would mean for his friends and the wizarding world in general. He may try to seek help from Dumbledore or other trusted allies.
Well, he might be in shock at first. I mean, Sirius is like a godfather to him, so the idea of marrying him is completely out of the ordinary. He could be filled with disbelief and confusion, not knowing how to even begin to process this strange turn of events.
Sokka would be protective of his sister. He would probably start by trying to negotiate with Zuko's side to call off the marriage. If that doesn't work, he might come up with a plan to rescue Katara, perhaps enlisting the help of their other friends and allies.
Well, their friends' reactions would be a mix of surprise and joy. Some, like George, might make jokes about how Harry and Hermione finally got together. But deep down, he would be happy for them. The other Hogwarts professors, like McGonagall, would be proud to see two of their best students starting a family. She might even offer to babysit on occasion. The friends would also come together to throw a big celebration for the baby's birth, and it would be a time for the wizarding community to celebrate the new addition and look forward to a bright future with this new generation.
The other Hogwarts students would have a wide range of reactions. Some might be shocked and gossip about it. Neville, for example, might be sympathetic towards Harry. Draco Malfoy could use it as an opportunity to taunt Harry, but at the same time be a bit envious of the attention this situation brings. The teachers would also have different responses. McGonagall might be worried about the impact on Harry's education and future.
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.
One interesting plot twist could be that they discover a hidden prophecy that states their union is the key to saving the wizarding world from a new, unknown threat. So, despite their initial resistance, they start to work together to fulfill this prophecy. Another could be that a powerful dark wizard has cast a spell on them, but as they try to break it, they actually start to understand each other better and form a real bond.
Well, a big theme is resistance. Hermione doesn't just accept the forced marriage easily. She fights against it in different ways, whether it's through magic or her wits. And there's the theme of unexpected love. Even though they start off in a bad situation, over time, they might develop feelings for each other. Also, there's the theme of social class conflict. Hermione being a Muggle - born and Draco a pure - blood, their union challenges the norms of the wizarding world, and this is often explored in these fanfictions.
Harry and Ron would likely be very shocked and concerned. They know Fenrir is a dangerous werewolf, and they might not understand how Hermione got into this situation. They would probably try to persuade Hermione to leave Fenrir at first.
