In this kind of fan fiction scenario, the relationship between Snape and Lily could have been explored in a whole new light. Maybe Snape would have been more open about his feelings earlier, and this could have led to a different sequence of events. Harry would also likely have a different personality, influenced by having Snape as a father figure. He might be more brooding or more academically driven from the start.
Well, if Snape became Harry's father in fan fiction, the whole dynamic of the story would shift drastically. Harry might grow up with a different set of values, as Snape was a complex character with his own moral code. He could be more proficient in potions from an early age. Also, Snape's relationship with the Order of the Phoenix and Dumbledore would have a more personal touch in relation to Harry.
One interesting plot could be how Snape reveals the truth to Harry. It could be a very emotional and tense moment. Maybe Snape has been hiding it for years out of fear or some other reason, and when he finally tells Harry, it completely changes Harry's perception of himself and his past.
Well, if Harry arrives at Hogwarts as a Snape fan, he might be more eager to get into Potions class. He could be constantly trying to impress Snape. Maybe he'd defend Snape more often against the other students' taunts. He might also study Snape's research and be more interested in the Dark Arts from Snape's perspective, which could lead him down a different path in his magical education.
One possible reason could be that in this fan fiction, Harry has developed a deep respect and a father - like bond with Snape over time. Maybe Snape has been secretly mentoring Harry in potions and has shown him kindness and understanding that Harry has never really received from his own father figure. This has led Harry to subconsciously view Snape as a father figure and the moment in potions class is just when this feeling overflows and he blurts out 'dad'.
Well, if Harry Potter becomes a Power Ranger fan, the story could change in many ways. Maybe he starts to incorporate some of the Power Ranger's fighting styles into his duels at Hogwarts. He might even dream of having Ranger powers to fight Voldemort.
Well, if everyone found out Harry was Snape's son, it would completely shatter the existing relationships. For one, Harry's relationship with the Dursleys might be even more strained as they already dislike him, and this new revelation could make them feel even more threatened. His relationship with Ron and Hermione would also be tested. They might be confused and even a bit betrayed at first. Hermione, being the logical one, would probably try to find out how this could be possible. Ron, on the other hand, might have a more emotional reaction. And as for Snape himself, his whole attitude towards Harry would have to change drastically. He couldn't keep up the pretense of hating Harry when it turns out he's his son. It would also change the way the wizarding world views Harry. Some might be more sympathetic, while others might be suspicious of Snape's motives all along.
The relationship would become more complex. Snape would have a certain level of control over Harry as his familiar. This would force Snape to be more responsible for Harry's well - being. Harry, in turn, would have to rely on Snape in a new way.
Snape might be initially shocked. His face could turn pale and his eyes widen in disbelief. But then, a small glimmer of something like pride or warmth might flash across his face for a split second before he quickly composes himself and snaps at Harry to focus on the potion.
If Harry finds out Severus is his father in fan fiction, it could completely change the dynamic between them. Harry's view of Severus would shift from hatred or suspicion to a complex mix of emotions. He might start to understand Severus' actions in a new light, like his seeming animosity towards Harry in the original story could be reinterpreted as a father's tough love. This revelation could also change Harry's relationship with the other characters. For example, his connection to the Snape family, if there are any in the fan - made lore, would become significant. It could also impact how he views his mother, Lily, and her relationship with Severus.
Some students might be shocked at first. They've always known Snape as this rather complex and often unfriendly character towards Harry in the original story. So, the idea of him being Harry's dad completely flips their perception.
