In the fanfiction, they might have a heartfelt reunion. They could share all the things they didn't get to say before. Maybe they'd talk about their friends left behind, like Remus and Harry. They'd probably also recall their adventures at Hogwarts, from the pranks they played to the battles they fought together.
In the fanfic, when Harry meets Viktor, they could end up having a friendly rivalry. They might challenge each other to a mini - Quidditch match just for fun.

Since Viktor is from Durmstrang, his training methods could be very different from what Harry is used to at Hogwarts.
Well, it could go a few ways. One possibility is that the Malfoys would start their typical taunting of Harry. Lucius might look down on Harry with disdain and make some veiled threats. Narcissa, on the other hand, could be a bit more reserved. Harry, being Harry, would likely respond with his own brand of courage. He might even try to use the situation to gain some information about the Malfoys' recent activities if he suspected they were up to no good.
In the fanfic, they might start by discussing the magical creatures in the zoo. Maybe they'll share their thoughts on how muggles perceive these animals without knowing their true magical nature.

He might also get involved in some secret missions that the Order is planning, adding his own unique skills and perspectives to the group. This could lead to new friendships and alliances within the wizarding world, and potentially change the course of future events in the fanfiction's storyline.
Perhaps James Sirius Potter is on a quest to clear his father's name in some way. He approaches Snape thinking he can get some answers. Snape, on the other hand, has his own grudges and secrets. Their meeting would then be a battle of wits and emotions as they navigate through the past and present issues.
In fanfiction, when James Sirius Potter meets the Dursleys, he might be shocked by their coldness. He could try to understand why they treated Harry so badly. Maybe he'd confront them about their past actions, or he might just observe them quietly to see what kind of people they really are.
In a fanfiction scenario, James Sirius Potter could be a bit of a troublemaker. When McGonagall meets him, she would have to decide how to deal with him. She could choose to be lenient, seeing the potential in him, or she could be very firm.

And she could start to encourage him to use his skills in a positive way, perhaps guiding him towards a particular area of magic study that she thinks would suit him.
In the fanfic, it might lead to a tense confrontation. Harry could feel anger towards the Malfoys as they are known for their prejudice. Draco might taunt Harry as usual, and Lucius Malfoy could look down on Harry with his typical haughty attitude.
