Snape, in turn, might start to open up a bit about his reasons for taking Harry. This could lead to a slow transformation of their relationship. They might find common ground in their shared experiences, such as both having lost people they loved to Voldemort. This newfound connection could start to heal the rift between them.

One interesting plot could be Snape taking in Harry after the death of Sirius. Snape, despite his initial reluctance, realizes he has a responsibility. He starts to train Harry in advanced potions and dark arts defenses in secret. This could lead to a unique bond between them as they gradually understand each other better.
Perhaps the plot is centered around Snape having some sort of misinformation. He takes Harry by force because he thinks Harry is in danger and he needs to protect him in his own way, which is rather forceful. This could lead to a lot of conflict between Harry and Snape initially, but then they might come to understand each other's motives as the story progresses.
It's popular because it creates an interesting dynamic. Snape has always had a complex relationship with Harry in the original series. When Harry is deaged, it gives Snape a chance to start anew and perhaps be a different kind of influence. It also allows for exploring Snape's more nurturing side which is a contrast to his usual cold persona.
One possible plot could be that Harry discovers a time - traveling accident has brought baby Snape to his present. Harry, being the kind - hearted person he is, takes it upon himself to care for the baby. He has to figure out how to feed the baby, keep him clean and comfortable. Maybe he also has to protect baby Snape from any threats in the wizarding world that might target Snape even as a baby.
Harry could also feel a sense of betrayal, especially if he thought Snape was on his side to some extent before. This feeling of betrayal might fuel his determination to resist. He might call out for help from his friends or any allies he has in the wizarding world. And depending on how long he is held by Snape, his reaction could evolve from pure anger and resistance to a more strategic approach of trying to understand Snape's endgame.
One popular theme is the mentor - mentee relationship. Snape, despite his initial animosity towards Harry in the original series, can be portrayed as taking Harry under his wing in fanfiction. This could involve teaching Harry more advanced potions or dark arts defense skills. Another theme is the exploration of Snape's hidden motives. In these stories, his actions towards Harry might be revealed to have deeper, more complex reasons. For example, he might be protecting Harry from a greater, unknown threat. Also, the theme of redemption for Snape is common. Fanfiction often delves into how Snape can find some sort of peace or absolution through his relationship with Harry.
Well, in such a fanfiction, it could greatly change the storyline. Snape is often portrayed as a complex and somewhat bitter character in the original story. But if he takes care of baby Harry, he might develop a different kind of bond with him. Maybe he'd become more protective and less resentful towards Harry as he watches him grow. This could lead to a completely different dynamic between Snape and the other characters too, like Dumbledore. He might not be as secretive from Dumbledore about his feelings for Harry.
