There are indeed some great Percy Jackson and Drew Lemmon fanfictions.

They might be friends in a different way or have a more complex relationship. Reading reviews on the fanfiction sites can help you find the really good ones.
Since I don't know of any existing Alyssa Calloway and Amanda Lemmon fan fiction, it's hard to say for sure. But common themes in fan fiction in general can include friendship, adventure, and personal growth. Maybe in stories about them, there could be themes related to their relationship, like how they support each other or overcome difficulties together.
One common theme is friendship. Writers often explore how Percy and Drew could become friends despite their differences. Another theme is rivalry, as they might compete for something in the story.

Jack was a man who was rather sly and liked to play tricks. He made a deal with the Devil and through his wits, he managed to avoid being claimed by the Devil immediately. But his actions led to him being barred from both Heaven and Hell.
In the 'Stingy Jack Story', Stingy Jack was a character who was both stingy and sly. He had the nerve to trick the Devil, which shows his audacity. He was not a moral person as his actions were mostly self - serving. His character is central to the story as his fate after death, being stuck between Heaven and Hell, is what the story is mainly about.
A prevalent theme is also their growth as individuals. Fanfictions may show how they develop their skills and personalities over time. For example, they might start as inexperienced musicians and grow into superstars. And of course, the theme of adventure can be found in some, where they embark on exciting trips or experiences together.
