Maybe Neville. He had a bit of a rough start at Hogwarts in primary school, but he grew so much. Attending the reunion would be a chance for him to show how much he's changed and to catch up with those who were there when he was finding his footing. He could share his experiences of becoming a confident and skilled wizard. Also, he might be excited to see the teachers who supported him along the way.
Well, they might reminisce about their early days at Hogwarts. Maybe talk about the first time they saw the Sorting Hat or their first flying lessons. It could be really nostalgic.
Ron Weasley is another popular character. His humorous nature and loyalty can be shown in different ways in the primary school fanfiction. For example, he might get into some funny situations while trying to help Harry with his magical secrets at school. Also, characters like Hagrid can be popular. He could be the one who secretly checks on Harry at his Muggle primary school and gives him little hints about the wizarding world.
Luna Lovegood could be a main character too. She always had a unique perspective on things at Hogwarts. At the reunion, she might share some of her strange but fascinating adventures since leaving school, and her presence would surely add a touch of whimsy to the gathering.
Well, they could re - establish old friendships that had faded over time. Maybe someone has a big announcement, like getting married or having a baby. There might also be a bit of rivalry resurfacing, especially if they compare their achievements in the wizarding world. They could also talk about how different their lives are from what they expected when they were at primary school. For example, a person who thought they would be a great Auror ended up being a Healer instead.
Obviously, Annabeth's immediate family like her parents if they are alive in the fanfiction would be there. Her siblings too, if she has any. And then there could be her extended family such as aunts, uncles, and cousins.
The primary school reunion of Harry and Daphne in the fanfiction might be a chance for them to reconnect with their past selves. Harry, having faced so many challenges since primary school, might find solace in the simplicity of his memories with Daphne. Daphne, on the other hand, could be curious about the rumors she has heard about Harry over the years. At the reunion, they might exchange stories, and Daphne could be impressed by Harry's tales of bravery. This could lead to them spending more time together, exploring the old school grounds and talking about how their lives have changed since those early days.
Probably Natsu. Since he has been searching for Igneel for so long, finding his family or getting some real family - related news would make him extremely excited. He's always been a bit of a lonely dragon slayer without his real family around, so a reunion would be a huge deal for him.
Obviously, Harry Potter himself would probably be there. Hermione Granger would also likely make an appearance. Ron Weasley would surely come along with his typical sense of humor. Neville Longbottom might show up, now a much more confident wizard. Luna Lovegood could be there too, with her unique perspective on things. And perhaps some of their less - known classmates from primary school would also be present, like Dean Thomas or Seamus Finnigan.
One possibility is that they recognize each other immediately and there is an instant sense of familiarity. Harry might be a bit shy at first, given his new - found fame and all the things he has been through. Daphne, being more confident, could break the ice. They could start by talking about their favorite memories from primary school, like a particular school trip or a class play. This simple conversation could lead to a deeper bond as they realize how much they have in common.
Friendship rekindlings would be a big part. There could be characters who had a falling - out in primary school and now see the reunion as a chance to make up. They might have a heart - to - heart conversation and realize that their old grudges were silly. And of course, there would be new relationships forming too, as some people who didn't interact much in primary school find that they have a lot in common now.
