Draco might develop a sense of independence. No longer under the influence of his family's dark beliefs, he could be making his own decisions. He may choose to study a new area of magic that has nothing to do with the Dark Arts or pure - blood traditions. In fact, he could be delving into the study of healing magic, which was previously looked down upon in his family.
In some fanfictions, Draco might start to question his family's loyalty to Voldemort. The events of the Goblet of Fire could expose him to the true horrors of the Dark Lord's plans, causing him to develop a more independent and moral stance. For example, he could see the harm that Voldemort's return brings to Hogwarts and its students, and this makes him reevaluate his associations.
In this type of fanfiction, Draco's character could develop in terms of his relationships. The experience of getting spanked could make him more vulnerable, and he may open up to people he previously kept at a distance.

It could also make him more introspective, leading to a change in his values and priorities within the wizarding community.

Draco could become more independent. Before getting his wand, he was probably more reliant on his family's name and status. But with his wand, he has his own tool to make things happen. For instance, he might start to explore parts of the wizarding world that his family doesn't control or influence. He could start to form his own opinions about magic, rather than just following what his father says. He might even start to see the value in Muggle - born magic, which would be a huge shift in his character.

On the other hand, if he's forced to kidnap someone for Voldemort, he might start to rebel against the Dark Lord as he sees the harm he's causing to an innocent person. His character could grow from a pawn in the Dark Lord's game to a more independent thinker.
In many fanfictions, Hermione will try to outwit Draco while she's kidnapped. She might use her vast knowledge of magic to escape or at least send some sort of signal to her friends. Meanwhile, Draco could start to have second thoughts about what he's done. He might realize that kidnapping Hermione was a wrong move, especially if he has some underlying feelings for her. This could lead to a change in his actions, and he may even start to protect her from other threats that might come his way, like other Death Eaters who want to harm Hermione for her connection to Harry.
