There's also 'The Slytherin Guard for Hermione'. This fanfic shows how some Slytherins, who have grown tired of the house's bad reputation, choose Hermione as the symbol of their change. They protect her from dark wizards who target her for her Muggle - born status. It's an interesting take on how Slytherins can be allies.
One reason could be that they see her intelligence as an asset. Hermione is known for her brilliant mind, and Slytherins, who value cunning and resourcefulness, might respect that. They could also recognize her strength in the face of adversity and be drawn to protect her as a way to show their own growth beyond the typical Slytherin - Gryffindor rivalry. In some fanfictions, a Slytherin might have a personal connection or debt to Hermione, which leads to their protective nature towards her.
Another theme is the idea of hidden alliances. In many of these fanfics, the Slytherins form a secret group to protect Hermione. This adds an element of mystery and intrigue as they work behind the scenes to keep her safe from threats, both inside and outside Hogwarts.
There are fanfictions where a Slytherin forms a study group with Hermione. And when other students try to disrupt her studies or cause her trouble, the Slytherin stands up for her. Also, in some stories, a Slytherin who has a secret crush on Hermione will protect her from any sort of harm, whether it's from a jealous rival or a dangerous magical creature that gets loose on the school grounds.
Well, in some fanfics, Slytherins might be protective of Harry in an abuse scenario because they see the injustice. They could be written as having a sense of fairness that overrides the typical house rivalries. Maybe they've come to understand Harry's situation better than others and feel compelled to protect him.
The themes often involve loyalty. Slytherins in these fanfics show loyalty to Harry in a way that goes against the stereotype of their house. Some fanfics also have the theme of family. Maybe a Slytherin character sees Harry as a surrogate family member and will do anything to protect him. There are also themes related to justice, where Slytherins protect Harry because they know he's the key to a just future for the wizarding world.
There are quite a few. Some fanfics focus on individual Slytherin students who form an unlikely bond with Harry. They might protect him from the dark forces that are after him, seeing him as more than just the 'Chosen One' but as a friend in need. These fanfics often explore the idea that not all Slytherins are bad and can be quite heroic when it comes to protecting someone they believe in.
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.
In abuse - related fanfics, Slytherins being protective of Harry can be a way to explore different character dynamics. It breaks the mold of the typical Hogwarts houses' relationships. Slytherins might be written as having a hidden soft side that emerges when they see Harry being abused. It could also be that the author wants to create a more inclusive and diverse story where traditional enemies can become allies.
