It develops in a complex way. There's a lot of mutual understanding and support growing between them.
Well, it depends on the writer's take. Some fanfics show Oliver as a strict big brother. He would push Harry to be the best in Quidditch, making him practice hard. He might also be a bit overprotective, getting into arguments with Harry's friends if he thinks they are leading Harry astray. However, in other versions, he's more of a laid - back brother, just there to support Harry and have a good time with him.
In many of these fanfictions, their relationship often becomes more intense and reliant. For example, in stories where they are facing the mystery of Riddle together, they learn to trust each other even more deeply. They might start to rely on each other's unique skills, like Harry's courage and Hermione's intelligence, in a more profound way.
Well, in many of these fanfictions, at first, Sirius is a bit wary of Hermione. He's been through a lot and isn't used to having someone so young and seemingly innocent be so involved in his life. But Hermione's determination wins him over. As they spend more time together, they start to understand each other better. Hermione learns about Sirius's past traumas and he discovers her hidden strengths. Their relationship evolves into a very strong bond, whether it's a platonic bond of friendship and mentorship or, in some cases, a romantic connection. For instance, they could be in a situation where they have to rely on each other completely to survive a dangerous encounter with a powerful dark wizard, and this experience cements their relationship even further.
In such fanfictions, their relationship often develops with Hermione taking on a more protective and guiding role. Since Harry can't hear, Hermione becomes his main source of information about the world around him at times. For example, in the classroom, she might be the one to quickly write down important instructions for him.
It could become very close and trusting. They'd know each other inside out and have a deep bond from childhood.
Their relationship often develops into a deeper, more trusting bond. Hermione's act of saving Harry makes him see her in a new light. He becomes more reliant on her, and she on him. For example, he may start confiding in her about his past abuse, which he never did before. This sharing of secrets brings them closer.
The relationship could also develop through a series of misunderstandings and reconciliations. They might misinterpret each other's actions at first, leading to some tension. But as they clear up these misunderstandings on the train rides, they grow closer. Eventually, all the pent - up emotions lead to that kiss on the train as a way of finally expressing their true feelings.
Some fanfictions develop their relationship through shared adventures outside of Hogwarts. They go on secret quests together, relying on each other's skills. Harry's courage and Hermione's intelligence complement each other during these adventures. As they face challenges and overcome them, their relationship blossoms into a romantic one while they keep it hidden from their friends.
In some fanfictions, their relationship might start with Harry being initially afraid or cautious of Hermione's new succubus form. But as he gets to know that she is still the same Hermione deep down, they start to build trust and their friendship evolves into something more, like a romantic relationship.
At first, it might start with simple moments of realization. Harry begins to notice how Hermione's presence makes him feel more at ease in different situations. As the story progresses, they might have deeper conversations that lead to a stronger emotional connection.
