Hermione would be horrified. She would immediately start trying to figure out a way to rescue Harry. She might start researching in the library for some ancient spells or forgotten magic that could help. Ron would be angry at Dumbledore and would probably want to rush off to save Harry without much of a plan at first.
The Hogwarts students would be shocked and scared. The younger students would look to the older ones for guidance. Neville would probably find some newfound courage and start thinking of ways to fight back against Voldemort. Ginny, who has her own experiences with Voldemort, would be determined to get Harry back and would be a strong advocate for taking action against Dumbledore's decision.
The teachers at Hogwarts would have diverse reactions. McGonagall might be disappointed but would still hope that Harry could resist the dark influence. Snape would be extremely complex in his reaction. Given his history with both Harry and Voldemort, he might see it as a sign of the prophecy coming full circle. The Death Eaters, on the other hand, would see Harry as a potential new leader. They might try to persuade him to embrace the dark side. As for Harry's other friends like Neville, he would be worried but would also stand by Harry, believing that he could make the right choice. The reactions of these characters would create a lot of drama and tension in the fanfic.
Well, the Weasley family would have a mixed reaction. Molly Weasley would be concerned about how this new relationship would affect Harry and whether Medea was a suitable partner. Ginny might be a bit jealous at first but then come to accept it. In the Hogwarts faculty, Professor McGonagall would be very strict in her assessment. She would want to ensure that Medea adhered to the rules and ethics of the wizarding world. The other houses, like Hufflepuff, might be more accepting overall, seeing it as a way to bring more diversity to the magical community. Slytherins, on the other hand, would be divided. Some would see it as an opportunity to gain an advantage through this new connection, while others would oppose it out of pure prejudice.
Ron would be extremely angry at first. He might feel betrayed by Harry. But as he realizes that something must be seriously wrong with Harry, he would probably join Hermione in trying to save Harry from Voldemort's influence. They would look for a way to break whatever spell or false belief has hold of Harry.
If Harry is turned into a weapon, Ginny would be heartbroken. She would be by his side constantly, trying to communicate with him even though he's in weapon form. The Weasley family as a whole would be outraged. They would see it as an attack on one of their own. Snape might initially seem indifferent but secretly would also try to find a way to reverse it, perhaps out of his complex feelings towards Harry and his loyalty to Dumbledore.
Hermione would be extremely worried and would start researching like crazy to find out where Dumbledore has taken Harry. She would probably suspect that something is not right with Dumbledore and would try to convince Ron to help her. Ron, on the other hand, would be initially shocked but then would be ready to go on a rescue mission with Hermione.
Voldemort would be calculating. He might be using the Armistice as a way to regain his strength or plot a new strategy. His Death Eaters would be divided. Some might be happy to have a break from the fighting, while others would be eager to continue the war. Dumbledore's followers would be watching closely too. They would be the ones to keep the balance and make sure that the Armistice doesn't turn into a way for Voldemort to take over completely. The Ministry of Magic would be in a difficult position, trying to enforce the Armistice while also dealing with the different factions within the wizarding world.
Hermione would be very concerned and would immediately start looking for a solution in the library. She'd be flipping through every magical book she could find, trying to figure out what spell or potion could reverse the effect. Ron would be a bit shocked at first but then would try to protect Harry as best he could. He might be a bit clumsy about it, like trying to keep Harry out of trouble in the Gryffindor common room. Dumbledore would likely be calm and observant. He'd probably already have some ideas about what's going on and would be subtly guiding the situation to ensure Harry's safety and the well - being of the wizarding world.
He'd probably be furious. Voldemort has a huge ego and most fanfiction would likely not portray him in the way he sees himself. He might view it as a form of disrespect to his 'true' nature and power.
Hermione would probably be extremely curious. She would want to research every aspect of Harry's elven heritage. She'd be poring over books in the library to find out if there were any precedents for such a thing. Ron, on the other hand, might be a bit more skeptical at first. He'd probably make some jokes about it but eventually come around.
At first, Dumbledore might see Harry as an even greater threat. But as he delves deeper, he could realize that Harry has the potential to be a powerful force for good, despite his dark lineage. So, Dumbledore would start to mentor Harry in a different way, focusing more on helping him come to terms with his identity and use it for positive change.
