Snape's character might develop by becoming more patient. Usually strict and harsh, teaching Harry could force him to be more patient and understanding, as Harry has a different learning style.
In fanfiction, Tom Riddle and Severus Snape are often depicted in complex relationships. Riddle, as the future Voldemort, represents pure evil. Snape, on the other hand, is a more morally ambiguous character. Fanfictions might explore how Snape would react to the younger Riddle at Hogwarts. Maybe Snape would be one of the few to see the darkness in Riddle early on.
One common portrayal in fanfiction is that of Snape being suspicious of Tom Riddle when he was still a student at Hogwarts. Snape, with his sharp intellect, might notice things about Riddle that others overlook, like his unusual interest in certain dark spells or his ability to manipulate those around him.
In the fanfiction world, if Snape was deaged to 16 by a potion, he might have a whole new set of challenges. Firstly, his relationships would change. He'd probably have a different dynamic with his peers at Hogwarts. His knowledge and skills would still be there, but his physical and emotional state would be that of a 16 - year - old. He might struggle to be taken seriously by those who knew him as an adult, and his interactions with students could become more complex as he'd be closer in age to them.
I'm not sure if there is a specific fanfic precisely on this combination. There are a vast number of fanfics in the Harry Potter fandom, and while there could be one out there that involves Snape, Hermione, and a potion related to a baby in some way, it would take some extensive searching through fanfic platforms to find it.
The potion could enhance Harry's magical powers. For example, it might make his spells stronger or more accurate. This would be useful in battles against dark wizards or in his general studies at Hogwarts.
His personality would likely become more impulsive. As a 16 - year - old, Snape wouldn't have the self - control he developed over the years. He might be quicker to anger and less guarded in his emotions.
Snape's character could become more calculating and cold - hearted. Tom Riddle is not exactly a nurturing figure, and being raised by him would expose Snape to a world of power - seeking and self - interest. Snape may lose some of his capacity for love and affection that he had for Lily in the original story. He would be more focused on achieving power and status within Riddle's regime. His relationships with other characters would be more transactional. For instance, he would not form the same kind of complex relationship with Narcissa Malfoy as he did in the original story because his priorities would be different, being centered around Riddle's goals rather than his own personal loyalties and emotions.
One great Severus Snape potion - related teenager fanfiction is 'The Potion Master's Apprentice'. It tells the story of a young witch who becomes Snape's apprentice in potions. The author does a wonderful job of capturing Snape's complex personality and the magic of potion - making.
Well, perhaps in the fanfiction, a villain uses a love potion on Harry to make him fall for Snape in order to create chaos in Hogwarts. Snape then has to deal with Harry's sudden affection while also trying to uncover the plot behind it. They might go through a journey of self - discovery and realizing that there are deeper emotions hidden beneath the false ones caused by the potion.
