Harry's reaction could be complex. Initially, he might be in disbelief and think it's some sort of trick or illusion. But once he realizes it's really them, he would be overcome with emotion. He could be a bit shy at first, not knowing how to act around them. But as time goes on, he would become more comfortable and start to bond with them, sharing his experiences in his own dimension and learning about theirs.
Well, the plot could start with Harry having strange dreams about his parents. One day, while exploring an old, forbidden part of Hogwarts, he accidentally activates a spell that transports him to an alternate dimension. His parents in this dimension are leading very different lives. They could be powerful wizards involved in some grand magical plan, and Harry has to figure out how he fits into this new world and how to get back to his own dimension.
Well, it could be that Harry meets his parents through some magical time - turner accident. Maybe he's on a mission in the past and stumbles upon them.
Well, it could be that Harry meets his parents in a special magical realm created just for them to reunite. His parents could show him some long - lost family magic that only their bloodline can use. And they might introduce Harry to relatives he never knew existed, which could change his perspective on his family history.
I haven't actually read this specific fanfic. But generally, if 'camp camp' meets Max's shitty parents in a fanfic, it could be a really interesting exploration of the characters. It might show how Max's relationship with his parents affects his experiences at camp, and how the camp environment in turn influences his view of his family situation.
There are so many things that could occur. For instance, Harry's parents could be curious about Hermione's relationship with their son. They might ask her about her family and her magical abilities. Hermione, on the other hand, could be eager to learn from them about Harry's early life. It could be a very emotional encounter, with lots of reminiscing about Harry as a baby and how much they missed seeing him grow up. And they might also share some secrets about the Potter family that could help Hermione and Harry in their later battles.
Obviously, baby Harry is one of the most important characters. He is the center of the story as he is the one having the encounter with his parents. And of course, his parents, James and Lily Potter. James, with his brave and mischievous nature, and Lily, with her kind and powerful magic, are crucial as they are the ones Harry is meeting.
Well, in such a fanfiction, baby Harry might experience a very warm and loving moment when he meets his parents. Maybe his parents would hold him gently, look at him with so much love in their eyes, and Harry would feel an instant connection to them.
Often, it ends with Harry feeling more confident and at peace. After meeting his parents, he has a newfound sense of purpose and is ready to face his challenges head - on.
