His older brother, James, might tease him a bit at first. But as he saw Albus struggling or being bullied because of his house, he would become protective. His sister, Lily, would likely be curious and want to know all about Slytherin. She might even visit the Slytherin common room secretly to see what it's like. Overall, the family would have a mix of reactions, but they would all love and support Albus in the end.
His father, Harry, would probably be initially shocked. But he would also be understanding and supportive. After all, he knew that Slytherin wasn't all bad. His mother, Ginny, might worry a bit more, especially about the potential for Albus to be influenced by some of the more traditional Slytherin values. However, she would also encourage him to be true to himself.
Harry would be conflicted. On one hand, he has his own past experiences and prejudices against Slytherin. But on the other hand, he knows better than anyone that people can't be judged by their house. He would try to hide his concerns from Albus, but Albus would sense them. Ginny would be more vocal about her concerns, but also emphasize that Albus can make his own path. James might initially be a bit disappointed, thinking that Albus should have been in Gryffindor like the rest of the family. But as time passes, he would realize that Albus is still the same brother, regardless of his house.
Well, a plot could revolve around Albus making unexpected friends in Slytherin. He might find those who are also outsiders in a way, like a half - blood who is looked down upon by the pure - blood elitists in the house. Together, they could work on changing the perception of Slytherin from within. Also, there could be a mystery in the Slytherin common room that Albus is determined to solve. It could be related to a former Slytherin's dark secret that has been plaguing the house for generations.
One great fanfic could be 'The Slytherin's Albus'. It shows Albus's journey in Slytherin, his struggles with the house's reputation and how he forms unique friendships. It's really interesting as it gives a new perspective on Albus compared to the original stories.
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.
One great fanfiction could be 'The Slytherin Journey of Albus Severus Potter'. In this fic, it delves deep into his struggle to fit in Slytherin while carrying the Potter name. It shows how he overcomes the initial prejudice from his housemates and becomes a respected figure in Slytherin.
Friendship is also a big theme. Albus usually forms unexpected friendships in Slytherin. These could be with other outcasts in the house or with students from different backgrounds. In some fanfics, he becomes friends with a pure - blood Slytherin who helps him understand the house's traditions better.
Another theme is redemption. In some fanfics, Slytherin has a bit of a bad reputation. Albus tries to redeem the name of Slytherin by his actions and choices. For example, he might work towards breaking the stereotype that all Slytherins are evil or self - serving.
Maybe he uses some powerful magic spell he learned at Hogwarts. For example, a protective charm that shields Harry from a deadly curse.
Snape might be cold and distant at first. He's not exactly the warm - and - fuzzy type. But deep down, he might see a bit of Harry in Albus and feel a sense of responsibility to guide him, just as he had watched over Harry in his own way.
There could be a fanfiction where Albus Severus Potter gets transported back in time to the era of his father's youth. He could witness the events that Harry went through first - hand, but also accidentally change some small things that have big consequences for the present time. He then has to find a way to fix the timeline without completely erasing his own existence.
Well, he might face a lot of challenges. In Slytherin, he'd be surrounded by students with different values compared to Gryffindor. He could have a tough time making true friends at first. But it might also give him a chance to change the perception of Slytherin from within. He could use his Gryffindor courage to influence the more cunning and ambitious Slytherins towards a more positive path.
