In a more complex plot, it could be set in an alternate universe where Severus and Harry are on the same side from the start. As part of a team - building exercise of sorts, Severus uses tickling as a way to break the ice with Harry and the other young wizards. This leads to a series of adventures where their new - found camaraderie is tested and strengthened through various challenges, with the tickling incident being a recurring theme that is both humorous and a bonding factor.
One possible plot idea could be how Snape deals with the physical and emotional changes during the pregnancy while still trying to maintain his role at Hogwarts. Another could be the reactions of other characters like Harry, Hermione, and Ron when they find out.
One idea could be that Severus, with his potions expertise, is recruited by the Bond - like organization in a world where magic and espionage co - exist. Harry, being a key figure in the wizarding world, gets involved too. Maybe they have to work together to stop a dark wizard who is collaborating with a group of evil non - magical villains.
One possible plot idea could be Harry growing up with a conflicted identity. Since Tom is often associated with dark magic and Severus has his own complex past, Harry might struggle to come to terms with his heritage. He could be shunned by some in the wizarding world who fear his connection to Tom.
If we consider the tickling in the context of trust - building. At first, Harry would be very defensive. But as Severus continues in a non - malicious way, Harry might start to open up. This could be a way for Severus to show his softer side to Harry, which is something Harry has never really seen before. They could start to share secrets during these tickling moments, like Severus might share some of his past experiences at Hogwarts when he was a student, and Harry would share his fears and hopes for the future. This would gradually develop a deeper, more meaningful relationship between them.
One plot could be that Harry Potter is bitten by a vampire during one of his adventures outside Hogwarts. He then has to struggle with his new vampiric nature while still trying to protect the wizarding world from dark forces. Another idea is that there is a hidden vampire community within the wizarding world that Harry discovers, and he has to deal with the politics and secrets there.
Well, it could start with Severus being a vampire in secret and Harry gradually finding out. Maybe Severus initially resists the urge to feed from Harry but then some situation forces him to. For example, he might be injured and need Harry's blood to heal.
One idea could be a story where Harry, Draco, and Severus are forced to work together on a dangerous mission to save Hogwarts from a new dark threat. They start off distrusting each other but gradually learn to respect and rely on one another.
One idea could be that they start off as enemies but are forced into a marriage by some magical law. As they live together, they gradually discover each other's hidden depths and develop a grudging respect that turns into love.
Perhaps Harry takes Severus, in his pet form, on a journey through the Forbidden Forest to find a rare magical herb that could potentially break the spell. Along the way, they encounter various magical creatures and face many challenges together. Harry starts to understand Severus better through this shared adventure, even in his pet form. For example, Severus in his pet form might show his loyalty and protect Harry from a dangerous Acromantula.
Well, perhaps Harry sings to Severus as a way to show him understanding or forgiveness. Maybe it's in a moment of reconciliation after years of animosity between them.
