Lily Potter is often a significant character. Since she was friends with Severus in the past and is Harry's mother, she can play a crucial role in fanfictions. Her relationship with Severus and how it affects Harry can be explored in different ways, like through memories or magical connections.
Well, Severus could be quite sneaky about it. He might start observing Harry more closely in the corridors and classrooms. If he notices signs of abuse, like Harry being overly withdrawn or having unexplained injuries, he could enlist the help of other trustworthy faculty members. He might also try to give Harry some extra tasks or projects in Potions class to keep him occupied and away from his thoughts about his family situation. This way, Severus can gradually build a relationship with Harry and offer him some form of support without making it too obvious at first.
In some fanfictions, there might be a plot where Harry discovers he has a long - lost family connection to Severus. For example, perhaps they are distantly related through some ancient wizarding bloodline. This discovery could lead to a whole new dynamic between them, with Harry seeing Severus in a different light and Severus feeling a sense of obligation towards Harry.
Well, 'Secret Encounters' is a Severus and Harry lemon fanfiction that many fans seem to like. It has a good balance between the emotional connection and the more adult - themed interactions. But be aware that this kind of fanfiction isn't for everyone as it can be quite explicit in nature. There's also 'Forbidden Love's Flame' which takes their relationship to a new level of passion.
Tom Riddle's family values are often associated with a thirst for power and a disregard for others. His family, being descendants of Salazar Slytherin, might have passed down a sense of superiority. In fanfiction, his family values could be shown as the root of his dark path. He may have been taught from a young age that pure - blood wizarding families are superior, leading him to view those without pure blood as inferior and worthy of subjugation.
Hermione would probably be one of the main characters to interact. She might be horrified at first to see Harry in such a situation and would try to find a way to free him. Ron could also be involved, perhaps being more impulsive in his attempts to rescue Harry, which might cause some problems. Dumbledore too would likely play a role. He might have some knowledge about the situation that he's not sharing right away, and his interactions with Severus would be crucial in determining Harry's fate.
Harry might develop from being resistant to the marriage to being more open - minded. He realizes that Severus is not just the strict teacher he once thought. For Severus, he may start to soften his tough exterior. He begins to see Harry not as James Potter's son but as an individual with his own merits.
Hermione is often a popular character. She can play the role of the mediator or the one who tries to figure out what's really going on between Harry and Severus. For example, she might notice the strange new dynamic between them and try to use her intelligence to uncover the truth.
At first, it's likely to be full of tension. Harry may be hesitant and even a bit resentful about the marriage, while Severus is his usual cold self. But as time passes, they start to see each other's good sides. Harry realizes Severus's intelligence and Severus sees Harry's courage in a new light.
Severus would probably use his knowledge of dark magic and potions to protect Harry. He could create protective spells and potions that would shield Harry from any immediate threats. For example, he might brew a potion that makes Harry invisible to dark wizards for a short period of time.
