If someone really wants Percy to at least tolerate it, they could try to find beer fanfiction that is more tastefully done or that has a different take on the concept. Maybe some fanfiction that uses beer in a more symbolic or light - hearted way rather than in a way that might be off - putting to Percy.
Well, it could be that Percy has had some bad experiences related to beer in real life, and seeing it in fanfiction just brings up those negative feelings. For example, if he had a family member with an alcohol problem, anything related to beer might be a turn - off, even in the context of fanfiction.
One thing that could be done is simply respect his opinion. Don't try to force him to read or like poker fanfiction. If others like it, they can enjoy it among themselves without involving Percy.
It could be that Percy gets involved in a conflict where he sides against Artemis' hunters. His actions in this conflict might make Artemis view him as an enemy. For example, if he accidentally harms one of her hunters while trying to protect someone else, she may grow to hate him.
He might be confused at first. Percy has always been a bit of an outsider among the gods, but he may not expect Artemis to hate him. So he would try to figure out what he had done wrong.
One possible reason could be a misunderstanding. Maybe there was some miscommunication or false information spread that made Artemis think Percy had done something unforgivable. For example, if Percy was wrongly accused of harming one of Artemis' beloved creatures or desecrating her sacred places.
The author of the fanfiction could rewrite it to better align with the characters' personalities. For example, by making Percy more in - character and the high school setting more unique.
Percy might be initially confused. He may not understand why his half - brother has such strong negative feelings towards him. He could try to talk to him to resolve the issue, thinking it's just a misunderstanding.
It could also be due to some family drama in the past. Perhaps there was a misunderstanding or a situation where Percy was favored by one of their parents unknowingly. Say, if Percy's father made a decision that seemed to benefit Percy more, like giving him a special weapon or training opportunity, which made his half - brother resentful.
