Another plotline could involve Albus Severus Potter seeking Snape's help to understand his father better. Since Snape knew Harry so well, he could share some insights that no one else could. Snape might be reluctant at first, but Albus's genuine curiosity could change his mind. They could also get into adventures together, like exploring some long - forgotten parts of Hogwarts where Snape had some secrets hidden. Along the way, Albus could start to respect Snape more and Snape could start to see Albus as an individual, not just as Harry Potter's son.
One possible plotline could be that Albus Severus Potter is initially shocked and a bit scared to meet the living Snape. Snape, on the other hand, might be initially cold towards Albus, but as they interact more, Snape could see a bit of Harry in Albus and start to warm up. They could end up having long discussions about the past, Snape's relationship with Harry, and how Albus can learn from the past mistakes. Maybe Snape could even teach Albus some advanced potions skills that are not taught in the regular Hogwarts curriculum.
Perhaps the plot could be centered around a mystery that only Snape and Albus can solve together. There could be some dark magic at play in Hogwarts that is related to Snape's past or something that was left unfinished. Albus's fresh perspective and Snape's deep knowledge of Hogwarts and dark magic combine to figure out what's going on. As they work together, they form an unlikely bond, and Albus comes to understand the complexity of Snape's character and the sacrifices he made.
Their relationship might start off rocky. Albus Severus Potter has grown up hearing different things about Snape, and Snape is not used to dealing with the son of Harry Potter. But as they spend time together, they could find common ground. For example, they both have a connection to the Potter family in different ways. Albus might start to admire Snape's intelligence and skill in potions, and Snape could see potential in Albus.
One possible plotline could be that Harry discovers a plot against Snape before it's too late. Maybe he overhears some Death Eaters planning to ambush Snape while he's on a solitary mission. Harry then uses his invisibility cloak and magic skills he's learned over the years to outwit the Death Eaters and save Snape. This would show Harry's growth as a wizard and his ability to set aside past differences with Snape.
For Albus Severus Potter, he could start off as a bit of a skeptic about Snape. But as he delves deeper into Snape's past, he could develop into a strong advocate for Snape's honor. He might become more confident in himself as he realizes the complexity of the wizarding world's history that Snape was a part of.
Perhaps Snape could help Albus Severus come to terms with his family legacy. Albus Severus is named after two great wizards, Albus Dumbledore and Severus Snape. Snape could share his own experiences of being in the shadow of great names and how to carve out one's own identity in the wizarding world. This encounter could be a very emotional and character - building moment for Albus Severus.
Well, Albus could finally understand Snape's true nature. Maybe he discovers the sacrifices Snape made for his family. He might apologize for any wrong assumptions he had about Snape in the past.
One possible plotline could be that Snape, in some alternate magical realm, gets a chance to meet Lily Luna Potter. He might initially be in shock, seeing the resemblance to Lily Evans. Maybe he tries to protect her from some unknown danger, using his vast knowledge of magic. He could also share some untold stories about her mother with her, creating an emotional bond between them.
The sister could have her own love story intertwined with the events of the wizarding world. She might fall in love with a Gryffindor, which would be a huge scandal in the eyes of some. This relationship could be a source of tension, not only within her family but also in the wider wizarding community. And as Severus tries to protect his sister from the dangers of the wizarding war, her relationship could add an extra layer of complexity to his already difficult situation.
One possible plotline could be that Snape discovers a hidden weakness of Voldemort. Maybe through his years of spying, he finds out that a certain spell, when combined with an ancient magic artifact, can destroy Voldemort. So he devises a plan to get hold of the artifact and uses the spell at a crucial moment when Voldemort is off - guard, perhaps during a major battle when Voldemort is focused on other opponents.
One possible plotline could be the daughter's struggle with her father's complex reputation at Hogwarts. She might face prejudice from students who remember Snape's dark past. Another could be her discovery of her father's true love for her mother, which was hidden for so long. And she could also have a special talent in potions, just like her father, and use it to outshine others in her classes.
Snape's reaction would be complex. He has so much history with the Potter family. At the start, he might show his usual cold exterior. However, if Albus shows respect and a genuine desire to learn from him, Snape could gradually warm up. He might share some of his potions knowledge and secrets that he never shared with others. He may also tell Albus stories about his mother, Lily, in a roundabout way, to help Albus understand his family's past better and the sacrifices that were made for him to be alive.
