His character could develop through the experience of being dragged behind. He might become more defiant, vowing to never be in such a powerless position again. For example, he could start training harder in magic to protect himself.
If Draco is dragged behind, it could be a humbling experience for him. He may start to see the world from a different perspective. He could realize that his actions have consequences and that he needs to be more careful. This could lead to him becoming more empathetic towards others, especially those who are often in vulnerable positions. He might also become more resourceful, learning to use his wits to get out of difficult situations like being dragged around against his will.
One possibility could be that Draco is being forced into a situation against his will. Maybe he's being dragged behind in a magical chase where his enemies are after him, and his friends or foes are pulling him along as they flee or pursue. It could also be part of a prank gone wrong in the wizarding world, where he ends up being dragged behind someone's magical transportation device.
Draco can be developed through his relationship with the bracelets. If they cause him pain or restrict his abilities, we can see how he copes with that. For example, he might become more determined to find a way to remove them.
To develop Draco's character, you could focus on its relationships. Let it have different types of relationships - a mentor - like relationship with an older, wiser sub creature, a love - hate relationship with a rival sub creature, and a loving relationship with a family member or a newfound friend. Through these relationships, Draco can learn different values and grow as a character. Additionally, exploring its fears and how it overcomes them would add more layers to its personality.
Draco's character could develop by first resenting the situation of being jailed and the collar that seems to be the cause of his misfortune. But as he delves deeper into the mystery of the collar, he discovers its connection to Hogwarts' heritage. This could lead him to become more protective of the school. His interactions with other inmates or people who visit him in jail could also shape his character. For example, if he meets a muggle - born who has a different perspective on magic, it could open his eyes and make him more inclusive. The collar could be a catalyst for all these changes, forcing him to reevaluate his pure - blood ideology and grow as a person.
Draco could be developed as a more empathetic character. For instance, he witnesses a cruel act by other Slytherins towards a non - pure - blood student. Instead of joining in or ignoring it, he stands up for the victim. This event could be a turning point in his character development, making him question the values he was brought up with.
Another way is to give Draco a new friendship or alliance in the fanfiction. Maybe he teams up with a character from the light side, like Hermione. Their interactions could help him grow. He could learn about different values and ways of thinking from her, especially when it comes to the power of the Deathly Hallows and how they should be used.
Draco can be developed by showing his struggle with the power of the timer ring. If it gives him great power, he could initially misuse it out of arrogance, but then learn to use it more responsibly as he grows. For example, he might start using it to get out of difficult situations without thinking of the consequences, but later realize the impact his actions have on others.
Draco can be developed by showing his vulnerability during the naked crawl. His pride is usually a big part of his character, so this situation would force him to face his insecurities. For example, he might be worried about what others think of his physical appearance. Also, his resourcefulness can come into play as he tries to find a way to end the situation or at least cover himself up.
Draco can be developed by showing his internal conflict. His disillusionment might make him question everything he once knew, and his 'naked' state (metaphorically) can expose his insecurities. Writers can develop him by making him face his past actions and grow from them.
He often becomes more self - reflective. When bound, he has to face situations that he can't easily escape from. This makes him look at his own actions and beliefs more closely. For instance, if he's bound to help the Gryffindors in a task, he starts to question his Slytherin - Gryffindor rivalry.
