Well, it could be a moment of reconciliation. Snape has been so harsh on Harry throughout most of their interactions. But in the fanfiction, the touch might symbolize Snape finally letting go of his grudges and seeing Harry as an individual rather than just a reminder of James Potter. It could be a very emotional moment for both characters and mark a turning point in their relationship.
In some fanfictions, Snape touching Harry could be a magical moment. It could be related to a spell or a transfer of power. Perhaps Snape is trying to share some of his knowledge or skills with Harry through this touch. This could lead to a new understanding between them and a different dynamic in their relationship compared to what we see in the original books.
Another view is that it could be related to the power dynamics. Snape is a powerful wizard, and Harry is also a significant figure in the wizarding world. The act of touching in the fanfiction could be about Snape asserting some sort of influence or trying to understand Harry on a deeper level. Maybe it's a way for Snape to gauge Harry's magical abilities or emotional state more closely, as touch can be a very intimate and revealing form of communication in the context of a well - written fanfiction.
One example could be a fanfiction where Snape secretly follows Harry during a dangerous mission outside Hogwarts because he's worried. He uses his skills to protect Harry without Harry realizing it, showing his hidden care.
One popular interpretation is that it shows a different side of Snape's character. Maybe in these fanfictions, Snape is shown to have a more paternal or protective instinct towards Harry, which is a huge contrast to his often cold and harsh demeanor in the original books. It could be a way for fans to explore the 'what if' scenarios, like what if Snape had been more open about his complex feelings towards Harry earlier on.
One possible interpretation is that it's a symbolic way of showing Snape's curiosity about Harry. In fanfiction, authors like to play with emotions and relationships, and this could be Snape's way of exploring the enigma that is Harry Potter.
One interpretation could be a form of extreme discipline. Snape has always been strict with Harry in the original series, and this could be an extreme version of that strictness. Another could be a comical take, where it's just a very absurd situation used for humor.
One interesting interpretation could be that he changes his look to blend in better during a dangerous mission. Maybe he cuts his hair short and shaves his beard to look less like the brooding Potions master that everyone knows. This would add an element of mystery and espionage to his character in the fanfiction.
In some fanfictions, Harry's dyslexia could be a sign of his unique connection to the ancient magic. Since he is often at the center of extraordinary magical events, his dyslexia could be a part of what makes him special. It could be that the magic within him is so strong that it affects his perception of normal reading and writing in the Muggle sense.
Well, in some fanfictions, Snape might be trapped in a magical trap set by Death Eaters who are still loyal to Voldemort's ideals. Harry, with his natural sense of justice and his loyalty to Hogwarts (where Snape also has a complex connection), figures out the trap's mechanism and manages to free Snape. Or perhaps Snape is on the verge of being attacked by a magical creature, and Harry, using his experience with magical creatures from Hagrid's teachings, scares the creature away and saves Snape.
Some fanfictions might explore how their Patronuses are linked to their family legacies. Since Harry has the connection to his father through the stag Patronus, and Ginny is part of the Weasley family, her Patronus could be related to some Weasley family trait. For instance, if the Weasleys are known for their loyalty and the Patronus of a dog represents loyalty, Ginny's could be a dog. And in the fanfiction, this could lead to interesting storylines where their Patronuses are not just symbols of their individual selves but also of their family heritages and how those heritages blend in their relationship.
One interesting Snape and Harry fanfiction could be one where Snape mentors Harry in a more private and less hostile way. They could bond over potions and Snape could finally see Harry as more than just James Potter's son.
