Fleur could be a bit hesitant at first, not fully understanding the situation. But once she realizes the gravity of Hermione's state, she becomes determined. She might call for help from other reliable wizards or witches she knows. Fleur would also comfort Hermione, telling her that she's safe now and that they will find the culprits. She may use her Veela charm in a subdued way to soothe Hermione's distress.
Hermione would likely be a mix of disappointed and worried. Disappointed because Harry is usually responsible, and worried because she cares about him. So she'd probably try to figure out why he got drunk in the first place.
She probably comforts him right away. Hermione is a very empathetic person. She might give him a big hug and let him cry on her shoulder.
He might initially show annoyance. After all, Hermione is often seen as a know - it - all in his eyes. But his sense of justice and his underlying good nature (despite his cold exterior) would kick in. He'd untie her in a rather brusque manner, but then start to question her about how she got into this mess. Depending on her answer, he might offer some cryptic advice on how to avoid similar situations in the future.
Well, Fleur is a complex character. When she finds out about Harry's abuse, she might initially be in disbelief. But once it sinks in, she would feel a deep sense of sympathy. Fleur might use her own experiences to relate to Harry. For example, she has faced prejudice in the wizarding world due to her Veela heritage. She could draw on that strength and determination to help Harry. She may offer him a place to stay away from his abusers, and use her magic to create a safe and comfortable environment for him. Also, she could start training Harry in some defensive magic so that he can protect himself in the future.
She might be initially terrified but quickly composes herself and starts thinking of ways to break free. For example, she could try to use a non - verbal spell if her hands are not completely restrained.
He may show a rare moment of kindness. Given his own past traumas and experiences, he might empathize with Hermione on some level. He could offer her some words of wisdom or even some form of magical assistance to help her get better.
He might be initially startled. Snape is used to seeing Hermione as a strong - willed and confident student. So seeing her crying could catch him off - guard. But then he might quickly put on his usual cold facade and ask her curtly what's wrong.
One possible reason could be that she was captured by some dark wizards who oppose her and her friends' actions. They might see her as a threat due to her intelligence and magical abilities. Another reason could be related to a misdirected spell or curse. Maybe someone was aiming for another target but accidentally hit Hermione and then tied her up to prevent her from seeking help immediately.
She might be initially shocked. After all, Draco is usually seen as this tough Slytherin. But then she could feel sympathy. For instance, she might offer him a handkerchief without saying much at first.
She might be very cautious at first. Hermione is a smart and brave character. She would probably try to gather as much information as she could about the Death Eater without being detected. Maybe she'd use a spell to keep herself hidden while observing the Death Eater's actions.
