In some fanfictions, Hermione might use her wits to try and outsmart Voldemort. For example, she could pretend to be on his side while secretly planning an escape or a way to undermine his plans. She's very intelligent, so she could try to find a weakness in Voldemort's defenses or his followers.
One popular fanfic could be 'The Dark Lord's Captive' where Hermione is kidnapped by Voldemort and she uses her intelligence to outwit him in unexpected ways. Another might be 'Hermione in the Dark Lord's Lair' which focuses on her psychological struggle while being held captive.
In some fanfictions, the focus could shift to Hermione's internal struggle. She might be forced to relive some of her worst memories or face her fears because of Voldemort's dark magic. However, this could also be the moment when she discovers new powers or strengths within herself that she didn't know she had, which she could then use to escape or fight back.
In a fanfic where Voldemort kidnaps Harry, it could lead to a lot of intense situations. Harry might be used as a bait to lure his friends into a trap. Or Voldemort could try to turn Harry to the dark side, using various forms of dark magic and psychological manipulation.
Well, Harry might discover some hidden passageways in Voldemort's lair. Since he has a lot of experience with tricky situations at Hogwarts, he could use his wits to find a way out. Also, he could try to appeal to any shred of humanity left in Voldemort's followers, if there are any, and get them to help him escape.
The main ethical issue is that it promotes and normalizes violence and sexual assault. Fanfic should not be a platform for spreading such harmful and immoral ideas.
Another theme is friendship and teamwork. Even though Hermione is the main character in these scenarios, she usually has help from her friends. They support her in different ways, like providing distractions or moral support during the fight against Voldemort. This shows that unity is important in the face of great evil.
She could be defiant at first. Hermione is a strong - willed character, so she might immediately start trying to escape or use her magic against Draco. She could also try to reason with him, asking him why he's doing this and trying to appeal to his better nature.
One possible motive could be fear. Voldemort is extremely powerful and if he threatened Hermione or her family, she might feel compelled to spy for him. Another motive could be a thirst for knowledge. Voldemort might have promised her access to dark magic knowledge that she couldn't get anywhere else.
