At first, Harry would probably be in shock. He's been through so much in his life, and this would be a huge new development. He might be a bit hesitant and scared, not sure if he's ready to be a father. But as time goes on, his Gryffindor courage would kick in and he'd start to take on the role with determination.
Harry could react with a mix of emotions. There would be disbelief, of course. He might think it's some sort of elaborate prank or a dark plot against him. However, once he realizes it's true, he would feel a deep sense of responsibility. His own experiences of growing up without parents would make him extra determined to be there for the child. He'd also be a bit worried about how the wizarding community would react, but ultimately, his love for the child would override any concerns.
One popular fanfiction could be 'Harry Potter and the Lost Kitten'. In this story, as a child, Harry discovers a magical cat that leads him on an adventure through the Forbidden Forest. It has elements of mystery and friendship.
The plot could be that the cat is a magical key to a hidden chamber. As a child, Harry stumbles upon the cat and realizes it has a strange mark. When he touches the mark, it reveals a map that leads him to a secret chamber filled with ancient magic and knowledge.
If Gandalf were to enter the world of the young Harry Potter fanfiction, the Hogwarts professors would have mixed reactions. Dumbledore would be intrigued and see Gandalf as an equal, interested in sharing magical knowledge. Snape, on the other hand, would be more guarded and perhaps a bit jealous of Gandalf's presence. The students would be in awe. Harry would see Gandalf as a new source of guidance and protection. Hermione would want to pick Gandalf's brain about all the different kinds of magic he knows. And the overall reaction in the fanfiction world would be one of excitement and a bit of chaos as everyone tries to figure out how Gandalf fits into their world.
Hermione would be very concerned and would immediately start looking for a solution in the library. She'd be flipping through every magical book she could find, trying to figure out what spell or potion could reverse the effect. Ron would be a bit shocked at first but then would try to protect Harry as best he could. He might be a bit clumsy about it, like trying to keep Harry out of trouble in the Gryffindor common room. Dumbledore would likely be calm and observant. He'd probably already have some ideas about what's going on and would be subtly guiding the situation to ensure Harry's safety and the well - being of the wizarding world.
In this kind of fanfiction scenario, Snape might initially be conflicted. On one hand, he has his long - standing dislike for James Potter, Harry's father. But on the other, his sense of duty as a Hogwarts professor could kick in. He might reluctantly start to heal Harry, all the while muttering under his breath about how much trouble Harry always seems to get into, just like his father. Then, as he heals Harry, he might start to see some of Lily, Harry's mother, in him and soften a bit.
Often, Harry will offer her a handkerchief or a tissue if there is one available. He might also put his arm around her in a comforting gesture. In 'The Common Room Crisis' fanfic, he does just that and then stays with her, listening intently as she pours out her feelings. He is patient and understanding, which is in line with his character in the original books. He tries to make her laugh or at least smile by sharing a joke or a funny memory. This shows his deep friendship and care for Hermione.
The pet might introduce Harry to new magical creatures or areas. For instance, if it's a cat that loves to explore the Forbidden Forest, it could lead Harry to discover hidden places or meet other magical beings that he wouldn't have encountered otherwise. This could expand his knowledge of the wizarding world and his own powers.
Well, in the fanfiction, Harry might first try to find the owner of the cat. He could use magic to see if there are any identification spells on the cat. Then, he might take it to Hogwarts. The cat could be a magical cat with special abilities, like being able to talk or lead Harry to a hidden place in the school.
Well, he might discover a whole new world of magic in that fanfiction. Maybe it contains spells that are not in the original books. He could get inspired to try out new things or it could even lead him to new adventures within the Hogwarts library, like finding a hidden section related to the ideas in the fanfiction.
It could be a snowy owl, just like Hedwig. In the original series, Hedwig was Harry's loyal and beautiful owl. A fanfiction might follow this idea and have Harry find a young snowy owl that he bonds with immediately.
