One reason could be loyalty. Snape is a complex character who has his own loyalties. He might force Draco into situations to test his loyalty to Hogwarts or to the side that Snape believes is right. For example, if there's a threat from Death Eaters in the fanfiction, Snape could force Draco to choose a side, either by directly confronting the Death Eaters or by helping to protect the school.
Perhaps Snape forces Draco to participate in dangerous tasks related to the wizarding war. He might believe Draco has a role to play in the fight against the Dark Lord. This could put Draco in a lot of danger, but also give him a chance to prove himself. Snape could use his position of authority to make Draco comply, like threatening to tell Draco's father if he doesn't. It's a complex situation that can vary a great deal depending on the fanfiction's plot.
Well, Snape might heal Draco because of his own sense of morality. Despite his dark exterior, Snape has a code of ethics. Draco is still a student, and Snape may believe that every student should be given the chance to survive and learn from their mistakes. Additionally, Snape could be acting on behalf of Dumbledore in some way. Dumbledore often had complex plans, and Snape was his agent. Healing Draco could be part of a bigger plan to keep the balance in the wizarding world.
In fanfiction, Snape might punish Draco for getting involved with the wrong crowd. For example, if Draco starts to associate with Death Eaters - in - training or those with malicious intentions. Also, if Draco fails to complete his academic tasks or cheats in exams, Snape would surely take action. This is because Snape values knowledge and academic integrity in Hogwarts. Additionally, if Draco causes trouble during important school events or ceremonies, Snape would likely punish him to set an example for other students.
A situation could be when Draco fails to follow Snape's instructions precisely in a potion - making task. Snape is a perfectionist when it comes to potions, and if Draco messes up the ingredients or the brewing process, Snape might yell at him out of disappointment. Another situation could be if Draco is caught bullying other students, especially those from non - pure - blood families. Snape, despite his own Slytherin loyalties, may not tolerate such behavior and yell at Draco to stop.
Snape might force Draco to protect him. Snape has his own complex motives in the wizarding world. By forcing Draco to learn certain skills or follow certain paths, he could be ensuring Draco's survival. For example, in some fanfictions, Snape sees Draco as a key to maintaining some sort of balance in the Slytherin house or within the Death Eaters' influence.
In some fanfictions, Snape might be trying to gain something from taking care of Draco. For example, he could be using it as a way to get in good with the Malfoy family or to gain some sort of advantage within the Slytherin house politics. However, as the story progresses, his feelings might change from self - serving to genuine care.
Snape often uses his own experiences to comfort Draco. He's been through a lot himself, so he can relate. For example, if Draco is struggling with the expectations of his pure - blood family, Snape might share how he dealt with similar pressures growing up.
One possible reason could be Snape's long - standing dislike for James Potter, Harry's father. Since Draco is from a pure - blood family like Snape himself, and Snape has a certain affinity for the pure - blood traditions and values, he might choose Draco. Also, Draco was in Slytherin, Snape's own house at Hogwarts, and he might have felt a stronger sense of loyalty to his house and its students.
Well, it might be because of a magical accident. Maybe he was experimenting with some dark magic that backfired on him. Or perhaps he was using a powerful spell without proper training. Also, in fanfiction, it could be related to his health. He could have an underlying medical condition that hasn't been discovered yet, like a weak heart or some sort of magical malady that causes him to faint when he overexerts himself magically.
Maybe Draco is jealous of Hermione's intelligence and abilities. In the fanfiction world, he could think that by making her his wife, he can somehow take credit for her achievements or keep her from outshining him. It could also be a power play. Draco might believe that having Hermione under his control through marriage would give him more influence in the wizarding world, especially if she has connections that he wants to use for his own gain.
