In a debate, one side would argue against the other side's point of view to strengthen their own point of view. The purpose of an argument was to let the audience better understand their point of view and persuade them to accept it.
There were a few points to note in order to successfully defend:
1. Fully prepared: Before the debate, you need to fully study your own point of view and the other party's point of view and prepare a strong argument to refute the other party.
2. Grasp the key points: You need to grasp the key points of the other party's point of view and refute them forcefully.
3. Use logic: You need to use logical reasoning to prove your point of view so that the audience can better understand your point of view.
4. Good at communication: You need to be good at communication and effectively communicate with the audience so that the audience can better understand your point of view.
5. Maintain confidence: You need to maintain confidence in your argument and believe that your point of view is correct and that you can convince the other party to accept your point of view.
Perhaps they argue over a girl. They are both heroes and might have feelings for the same person. Jealousy and competition could spark an argument between them. Also, their loyalty to different camps, Camp Half - Blood and Camp Jupiter, could be a source of conflict. They might have different ideas on how to handle the relationship between the two camps, which would lead to arguments.
Gabi remains alive in the manga. The plot doesn't lead to her death. It's one of those character arcs where she continues on despite facing various challenges.
For a more villainous touch, including Voldemort or his followers could create high - stakes situations. Bellatrix Lestrange could be a terrifying adversary for Harry and Gabi. On the other hand, adding new original characters, like a powerful but reclusive wizard who lives in the Forbidden Forest, could also make the story more exciting.
