In fanfiction, how does Harry's protectiveness of Draco usually manifest?

Well, in such fanfictions, Harry's possessiveness might show in him being overly protective of Draco. For example, he may not like Draco interacting with other people too much and always wants to be around Draco to ensure his safety or just to be close to him.

He could also react with suspicion. Draco might think that Harry has some ulterior motive, especially if the confession is of a more positive nature like friendship or love. He would question Harry's sincerity and might even test him in some way.

Often, Ginny will try to insert herself between Harry and Hermione. She might constantly try to get Harry's attention when he's with Hermione or try to exclude Hermione from activities that involve Harry. In some fanfictions, Ginny might even spread rumors about Hermione to try and drive a wedge between her and Harry.

Another way her anger could manifest is by getting the school or other authorities involved. If Katsuki's actions towards Izuku are really bad in the fanfiction, Inko might go to the school principal or a hero agency to complain about Katsuki's behavior, hoping to get him to stop his mean - spirited actions towards her son.

One way their protectiveness shows is in the social aspect. Slytherins are known for their loyalty to their own. They would include Draco in all their activities and not let him feel left out. If there were rumors going around about Draco, they would quickly squash them. In dueling situations, they might form a protective circle around him, using their skills to keep any opponents at bay. And when it comes to academic competitions, they would support Draco wholeheartedly, even helping him study in secret if needed.

His jealousy could also show in his magic. Maybe he tries too hard to outperform Fleur in magic tasks or challenges. He might be constantly comparing himself to her and pushing himself to the limit just to prove that he is better, which is a sign of his jealousy.

It deepens their bond. Harry starts to trust Cedric more, seeing him as a reliable friend. This protectiveness makes Harry feel safe around Cedric.

Typically, in fanfiction, the forced bond between Harry and Draco is often magically imposed. It could be the result of a dark magic spell gone wrong or a powerful magical artifact. For example, a cursed necklace that once put on, binds them together in some way. This bond then forces them to experience each other's emotions, thoughts, or physical sensations.

Well, Draco might make Harry blush by showing off his intelligence in a way that Harry finds impressive. In some stories, Draco is really good at potions or some other subject, and when he demonstrates his skills in front of Harry, Harry can't help but blush. Another way is through Draco's unexpected acts of kindness. Harry is so used to their rivalry that when Draco does something nice, like helping him with a difficult spell, it makes Harry blush.

In certain fanfictions, Harry Potter's healing powers could be related to his connection with magic on a deeper level. His healing might be tied to his strong will and the power of his positive emotions. So when he focuses on helping someone, his magic channels that energy into a healing force. It could also be that his experiences with love and friendship have unlocked this latent healing ability, allowing him to heal not just physical wounds but also emotional scars of those around him.
