Maybe it's a game of Quidditch in the fanfiction. Harry, as a skilled Seeker, would be on his team, and Draco would be on the Slytherin team. They would compete fiercely in the air, trying to catch the Golden Snitch. There could be a lot of trash - talking between them during the game, and in the end, it could be a very close call as to who wins.
Well, it could be a wizard's duel game. Harry and Draco, being rivals, might use their unique spells and skills. Harry could rely on his Gryffindor courage and spells like Expelliarmus, while Draco would use his Slytherin cunning and some dark - ish spells he's learned from his family. The game could be set in the Hogwarts grounds, with other students as spectators.
Maybe it could be a magical duel. In the wizarding world, duels are common. Harry, Draco, and Tracey might have some special rules like they can only use certain spells. For example, they can't use Unforgivable Curses. Each time they successfully cast a spell on the other, they get a point.
Perhaps the Snitch has been enchanted in a way that it can only be caught if Harry and Draco combine their magical abilities. They initially resist working together because of their past rivalries. But as the game progresses and they realize this is the only way, they start to communicate and use their unique skills together. This could be a big step in mending their relationship.
In the 'Harry and Draco in Prison' fanfiction, it could be that the wizarding world has a new, strict regime. Harry, being the symbol of the resistance against dark forces, is imprisoned to silence him. Draco, who has always been on the fence between good and bad, is also thrown in prison for not fully conforming. Inside, they initially clash due to their long - standing rivalry. However, as time passes, they realize that the real enemy is the unjust system that put them there. They combine their skills, Harry's courage and Draco's cunning, to start a prison - wide revolt and try to bring about change in the wizarding world.
However, if it's a game that requires cunning and manipulation, like a Slytherin - style strategy game, Draco might come out on top. He's been brought up in an environment where such skills are valued and taught.
One possible exciting plot could be that during the one - on - one seekers game, there is a magical interference. Maybe a dark charm has been placed on the Golden Snitch, causing it to behave erratically. Harry and Draco both suspect foul play but from different angles. Harry thinks it's a Death Eater plot to disrupt Hogwarts' games, while Draco initially suspects Harry of using some new Gryffindor trick. As they chase the Snitch, they start to work together unknowingly to figure out the source of the interference.
Well, perhaps the plot could involve Harry and Draco putting aside their past differences to give Teddy a stable and loving home. They might struggle at first with co - parenting due to their long - standing rivalry. But as they get to know Teddy better and see how much he needs them, they start to work together more smoothly. Maybe they also have to protect Teddy from some dark forces that are after him because of his parents' history.
One possible plot is that Harry and Draco are forced by some unforeseen circumstances to raise Scorpius. Maybe there's a threat to Scorpius's life, and the only way to protect him is for these two former rivals to work together. They gradually learn to understand each other better through the process of taking care of Scorpius, and in turn, they pass on their combined wisdom to the young boy.
Perhaps in the fanfiction, Draco and Severus leave Harry because they are forced to by some external dark force. This could lead to Harry having to face new challenges alone, while Draco and Severus struggle against this force in their own way. They could end up being spies or trying to find a way to defeat the dark power from afar.
Perhaps they go to Forks to start a new life away from the wizarding world. They could find common ground with the outcast characters in Forks. Harry, with his experience of being an outsider in the wizarding world, and Draco, who has also had his own issues of fitting in, might bond with the misfits in Forks. They could end up helping the local community while also learning about themselves.
One possible plot could be that Harry and Draco, after years of rivalry and then gradually getting to know each other better, find themselves in an unexpected situation where they have a child together. Maybe it starts with a magical accident that binds their magic in a way that results in a baby. They then have to deal with the shock from their friends and family. Harry's friends like Ron might be initially very skeptical and angry, thinking Draco is up to something. But as time goes on, they see that Draco has changed and that he and Harry truly care for the baby and each other.
