In the 'harry shows draco up in a duel' fanfiction, how does Harry manage to show Draco up?

Draco might become more bitter and resentful towards Harry. He could start plotting some form of revenge in the fanfiction.

Well, perhaps Harry uses his quick thinking and his knowledge of magical creatures. He might step in just in time, using a spell to distract Buckbeak before it can harm Draco. For example, he could use a simple levitation spell to lift a small object and draw Buckbeak's attention away from Draco.

In this fanfiction, Harry might also save Draco by appealing to Lucius' sense of self - preservation or family. He could threaten to expose some of Lucius' secrets or illegal activities if he doesn't let Draco go. Or, if there is some underlying family drama involved, Harry could use that to his advantage. For instance, if there's a feud within the Malfoy family that Harry is aware of, he could manipulate the situation in a way that makes Lucius back off and leave Draco unharmed.

At first, Draco might be in shock. He didn't expect Harry to break up with him at such a crucial time. Then he could try to reason with Harry, begging him to stay for the sake of their unborn child. When Harry refuses, Draco could turn to his own family for support and close himself off from the outside world for a while.

Harry could initially be angry and struggle. He's a brave character, and being tied up against his will would surely make him fight back. He might yell at Draco, demanding to be released and threatening consequences.

There could also be a chance for reconciliation in the future. Maybe they both realize that they made mistakes during the break - up. Draco could change his ways a bit more and Harry could be more understanding. Fanfiction often has these kinds of arcs where characters get a second chance at their relationship after some growth and learning.

In the fanfiction, their friendship could develop gradually. At first, they might be forced to work together on a school project. Draco, who is used to being in control, might be frustrated by Harry's different approach, but as they work through the problems, they start to respect each other's skills. This mutual respect then grows into a tentative friendship as they continue to interact more in school and outside of it. They might also find common interests in things like magical creatures that they initially thought only they were interested in.

Well, it could be that Harry discovers Draco's plan in advance. He then sets up a counter - plan. When Draco tries to harm Ginny, Harry jumps in, using his invisibility cloak to his advantage, surprising Draco and rescuing Ginny.

There are also some fanfictions where there is no clear winner. The duel might be interrupted, or they could end up in a draw. This can lead to a more complex relationship development between them as they both have to come to terms with the fact that neither is clearly superior in a duel.

It's possible that in this fanfiction, Harry has a false perception of what's best for Ginny. He might think that by getting her to marry Draco, it will solve some long - standing issues in the wizarding world. So, he uses a combination of persuasion, magic, and false information to 'tick' Ginny into it. He could be telling her that it's the only way to end a brewing war or to bring peace among different wizarding families. Ginny, being trusting of Harry, might then start to consider the marriage to Draco.
