There could also be a plotline where a character is poisoned, and the poison causes their body to slowly break down, resulting in bleeding. Maybe a character unknowingly drinks a potion that was meant for someone else, and the effects start to show during an important event at Hogwarts. The other characters would then have to figure out what the poison is and find an antidote while the victim is slowly bleeding out, adding a sense of urgency and mystery to the story.

It could be a fight between two rival students or even between a Death Eater and an Order of the Phoenix member. This could create a tense and dramatic situation where other characters have to race against time to save the injured one.
