Artemis might find Percy when he's broken because of a shared emotional connection or a magical bond. Maybe she's been secretly watching over him and senses his distress. Another possibility is that a friendly deity alerts her to his condition.
Initially, Percy is likely to be heartbroken. He thought he had a certain relationship with Artemis, whether it was friendship or respect. So when she betrays him for Orion, he may go into a state of self - doubt. He could wonder what he did wrong and start to isolate himself. But as time passes, he may gather his strength and decide to face Artemis and Orion head - on, to either regain Artemis's trust or show her the error of her ways.
Percy could also use his strategic mind. He has been through many battles and knows how to plan defenses. He might scout the area around Artemis and set up traps or early warning systems to protect her from any approaching danger. This would involve using his knowledge of the terrain and his skills in combat to ensure her safety.
Percy could also react with a sense of determination. Instead of being defeated by the injury, he sees it as a challenge. He starts to figure out what made Artemis hurt him in the first place. If it was a misunderstanding, he tries to clear it up. If it was something more malicious, he starts to plot his revenge. He uses his own wits and the powers he has to either heal himself or find a way to make Artemis see the error of her ways. He might also seek the help of his friends, like Annabeth or Grover, to come up with a plan to deal with the situation.
Well, Artemis could take advantage of Percy fanfiction by using it as a source of inspiration. Fanfiction often contains creative interpretations of the characters. Artemis, as a character, can benefit from these new takes. In some fanfictions, she might be involved in adventures with Percy that show different aspects of her personality, like her leadership skills or her compassion. This can attract more fans to her character and also give the writers of the official works new ideas on how to develop her further.
He probably tries to stay calm at first. Percy has been in tough situations before, so he would assess the situation.
He may also try to figure out what went wrong. Percy is a smart demigod, and he would likely not just accept the betrayal without trying to understand the cause. So, he might start investigating, talking to other characters who might have some insight, like the other demigods or even some minor gods who are friendly to him.
She would probably be furious. Artemis has a strong sense of justice and protecting the vulnerable. So, she would likely immediately start to plan how to deal with those responsible for Percy's abuse.
She could also be angry. Given her power and status, she might feel slighted by Percy. She may take some form of revenge, not in a malicious way but perhaps by making Percy's life a bit more difficult during his quests. For example, she could send her hunters to interfere or withhold some information that could be useful to him.
Well, 'Percy' could be a person's name. If he 'owns' Artemis fanfiction, it might mean he has created it, or perhaps he has the rights to it in some way, like he's the author or has obtained the rights legally. Maybe he's a big fan of Artemis and decided to write some fan - made stories about her.
He may show a rare moment of kindness. Given his own past traumas and experiences, he might empathize with Hermione on some level. He could offer her some words of wisdom or even some form of magical assistance to help her get better.
