It would likely make Draco more self - reflective. Discovering a twin would force him to question his own identity. He might start to see himself not just as a Malfoy heir but as an individual separate from the expectations placed on him by his family.
Draco's relationships with others would change. For instance, his relationship with his parents might become more complex as they deal with the existence of another child. And his friendships at Hogwarts, like with Crabbe and Goyle, could be affected as he spends more time trying to understand his twin.
The twin could change a lot. He might be the one who stops Draco from making some really bad decisions. For instance, if Draco was about to follow Voldemort's orders blindly, the twin could convince him otherwise. This would then change the whole course of Draco's actions and how he interacts with Harry Potter and his friends.
Well, Snape's care can make Draco more confident. Knowing he has someone like Snape looking out for him gives him a sense of security.

When the nightmare is about his own misdeeds, it can be a turning point for his character. He might become more remorseful and try to make amends for his past actions. This could involve him being nicer to those he's bullied or trying to help in the fight against the Dark forces instead of being on the wrong side.
Draco's character could develop in terms of his values. With a daughter, he might start to question the pure - blood ideology he was raised with. He realizes that love and family are more important than blood status. He may even start to advocate for a more equal wizarding society so that his daughter can grow up in a better world. He becomes more of a protector, not just of his family name but of his daughter's future and well - being.
She could be really kind. In contrast to Draco's sometimes haughty attitude, she might be the one who is always helping out the first - years, showing them around Hogwarts and making them feel welcome.
Draco's character would likely become more complex. With the Elder Wand in his possession, he would have to face the responsibility that comes with such power. He might start to question his previous beliefs and actions, and grow into a more empathetic and self - reflective person.
The memory loss can be a catalyst for Draco's growth. He has to re - evaluate his identity. He might discover that he was not truly happy with the person he was before. As he struggles to remember, he could develop traits like humility and empathy. For instance, if he was once arrogant towards house - elves, during his memory loss, he could interact with them in a more equal and kind way. When his memory comes back, he may choose to keep these new - found qualities, changing his character for the better.

At first, it could be strained. Draco, being used to being the only son in the family's eyes, might feel threatened by his twin. He could be jealous if his twin shows more magical talent or is more popular at Hogwarts. But as they grow older, they might start to understand each other better. For example, if they face a common enemy, like a bully from another house, they could come together and realize the importance of family.
