Well, it could be a turning point in the story. Maybe before throwing up, Percy was overconfident or ignoring some danger signs. His vomiting could be a sign that he's not as invincible as he thought. This could lead to him re - evaluating his actions and changing his approach in the story. Also, it can add some drama. His friends might be worried and start arguing about what to do, which can create interesting character interactions.
It can add a sense of realism. Just like in real life, when a character is sick or nauseous, it makes the story more believable.
The demon lord can greatly impact the story by creating high - stakes conflicts. Their presence forces the heroes, like Percy and his friends, to step up and use all their skills and powers to combat the threat.
In fanfiction where Sally dies, it's a major turning point. Percy's character development could take a different route. Instead of having his mother as his anchor, he has to find strength within himself. This could make him more reckless at times as he no longer has that voice of reason in his life. It might also make the other characters step up more to support Percy, like Annabeth having to be more of a stabilizing force for him. And the story could then focus more on Percy's internal struggle with loss and how he copes with it in the world of demigods.
Grover would be panicked. He's Percy's friend and he cares a great deal about him. He might start running around trying to find help, like looking for a healer or someone with magical healing abilities. He'd probably be muttering to himself about how he should have protected Percy better.
It could be a turning point in the plot. For example, if he throws up after being poisoned, it might lead to a search for the culprit and a whole mystery - solving arc. His friends or family might get involved in finding out who did it and why.
Perhaps he has been exposed to some sort of deadly and unknown substance in the mythical world. This could be a new type of monster venom or a strange plant that he accidentally ingested. The substance could be attacking his body from the inside, causing his internal organs to bleed, and thus he throws up blood.
Well, it could be due to some sort of magical potion gone wrong. Maybe he drank something that was supposed to give him extra strength but instead made his stomach turn. Another reason could be that he got poisoned during a battle with a monster. Some monsters might have venom or toxins that could make him sick to his stomach.
The scene can add depth to the overall mood of the fanfiction. It creates a sense of realism and emotional intensity. It makes the story more than just about magic and wizardry but also about the complex emotions of the characters. It can draw the readers in more deeply as they empathize with Draco's pain, whether they previously liked him or not.
If Percy is taller in fanfiction, it might make him seem more imposing in his relationships. His friends could look up to him literally and figuratively. In romantic relationships, a taller Percy could be seen as more protective. For example, he could easily shield his partner from danger.
It could be related to a new and strange power he's trying to control. Percy is constantly evolving and getting new powers. If he tries to tap into a power that his body isn't ready for, it might have some adverse physical effects like vomiting. Like when he first started to understand his water - based powers, there could be something similar but more extreme with a new power.
