One reason could be for a disguise. Maybe he's on a secret mission and needs to pass as someone else. Another could be peer pressure. His friends might have dared him to do it.
In some fanfictions, it might be a sign of his growing independence from his traditional pure - blood family values. Shaving his legs could be something that his family would frown upon, but he does it anyway to assert his own identity. It could also be related to a romantic plot, where he wants to look good for someone special.
Yes, there are some out there. You can try searching on popular fanfiction websites. Some might explore the idea in a humorous way, like Draco trying out a new trend or getting into a bet that involves shaving his legs.
One possible reason could be his father's strict and cold parenting style. Lucius Malfoy was often very controlling, pushing Draco to uphold the family's pure - blood ideals and reputation, which might have made Draco feel suffocated and resentful. Another reason could be that Draco witnessed his father's dark deeds in the wizarding world, like being involved with Voldemort, and he might have moral objections to such actions.
One possible reason could be their long - standing rivalry. Draco has been taught to dislike Harry from a young age due to their family differences. His pure - blood supremacist upbringing might make him reject Harry as a mate because Harry is seen as a 'Mudblood - lover' in the eyes of Draco's family and their circle. Another reason could be fear. Draco might be afraid of what the wizarding society would think if he accepted Harry as his mate. The wizarding world has its own set of norms and expectations, and a relationship between them would be highly unconventional and likely face a lot of opposition.
Maybe he wants to rebel against his family's traditional image. In the wizarding world, the Malfoy family has a certain 'pure - blood' and proper image. Dyeing his hair could be a way for Draco to show his individuality and break free from the constraints his family has put on him.
Perhaps Draco realizes that Harry is in a dire situation where he needs the wand to save the day. Draco, having a change of heart, decides to give Harry his wand as a way of contributing to the greater good. This could be related to a looming threat that only Harry can face, and Draco understands that his wand can be a crucial tool for Harry.
One possible reason could be his Slytherin pride and the long - standing rivalry between Gryffindor and Slytherin. He might have said something mean to Hermione in the heat of that rivalry. Another reason could be jealousy. Maybe Hermione is achieving more academically or getting more recognition, and Draco, being a proud pure - blood, can't stand it.
In some fanfictions, it could be a result of some magical influence. Maybe there was a spell or a charm that made Harry act this way. Or it could be an expression of deep - seated emotions that Harry has been suppressing for a long time. This action then becomes a way for him to break free from his self - imposed restraints and reach out to Draco in a very physical way.
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.
One possible reason could be the pressure he faces from his family. The Malfoy family has high expectations and a dark reputation. Draco might feel suffocated by the need to uphold the family name and follow their dark path, which could lead to him breaking down and crying in the bathroom where he can be alone.
Love. Just like any other character, Draco can be heartbroken in fanfiction. If he loses someone he loves, whether it's a friend or a romantic partner, he could cry. It shows his vulnerability and that he's not just the tough - guy Slytherin he often tries to be.
