They would probably be cautious. Given Draco's family connections to the Death Eaters, they would be worried about potential traps or retaliation. So, they would keep a close eye on him at all times.
The Order might try to rehabilitate Draco. They could see that he is young and perhaps has been influenced by his family's wrongdoings. They would introduce him to the values of the wizarding world that oppose Voldemort, like equality among wizards and witches regardless of blood status. Members like Lupin or Tonks could be involved in this process, as they are more empathetic characters. They would talk to Draco, share stories, and try to make him understand that there is a better way to live.
He might be interrogated. The Order could be trying to get information from him about the Death Eaters' plans or Voldemort's whereabouts. They would likely keep him in a secure location within their headquarters.
His character would likely become more empathetic. Being around the members of the Order, who fight for good, would expose him to different values. He might start to question the beliefs he grew up with as a Malfoy.
Well, one aspect could be the unique take on the relationship between Hiccup and Draco in the fanfiction. It might explore how Hiccup's character, known for his ingenuity and courage in his original story, copes with being captured by Draco. Maybe Draco has some ulterior motives in this fan - made scenario.
In some fanfictions, Draco might help the Order by providing inside information from the Death Eaters. Since he's from a Death Eater family, he could have knowledge about their plans or movements.
If they join the Order, their relationship could transform in many ways. Lucius, as a father, might feel a sense of pride in Draco for making a different choice. Draco, in turn, could see his father in a new light, as someone who is willing to change. However, there could also be some strain. Lucius has a lot of baggage from his past deeds, and Draco might struggle with how to deal with that while still supporting his father in the new environment of the Order.
She could stand up to him. Hermione is known for her intelligence and quick - wittedness. So she might use her sharp tongue and logical arguments to put Draco in his place. For example, she could expose his wrongdoings or the flaws in his pure - blood ideology.
You can expect a lot of character - driven drama. Since Hiccup is captured, there will likely be a lot of tension between him and Draco. This could be a great opportunity for the author to explore the personalities of both characters more deeply.
Luke's character development in such a fanfiction would be complex. Initially, he would be full of defiance towards Vader, but as the captivity continues, he might start to feel a sense of hopelessness. However, this would also be a time for self - discovery. He could learn to control his emotions better, as any outburst could be used against him by Vader. His view of the Force could also expand. He may come to realize that the power of the Force is not just about combat but also about inner peace and understanding. And through his interactions with Vader, he might develop a stronger sense of purpose in his journey as a Jedi, vowing to not let the dark side overtake him or others.
In some fanfictions, Draco might initially become withdrawn. He could isolate himself from others, brooding over the rejection. For example, he might stop participating in social events he used to enjoy.
Konoha could also try to rehabilitate Deidara in some fanfic ideas. They might see if they can turn him away from his violent and destructive ways. Maybe they'd assign some ninja with good persuasion skills to talk to him and make him see the error of his ways. They'd also keep him under strict surveillance during this process.
