I have an urge to rewrite Percy Jackson but make the timeline to make the most sense for multiple (2) reasons.
1) Percy should not have been in his junior year when Hera kidnapped him. He had just finished his freshman year when The Last Olympian happened so he should have been going into his sophomore year, because he should not have also been 17 during his senior year, he should have been 18. (I get upset about this plot hole almost every day) and
2) Nico should not be older then Hazel. When we meet him in Titans Curse he was 10, and then turned 11 a few weeks after (if we disregard the fact that he was in the Lotus Casino and that may have messed with his age but I digress). During Battle of the Labyrinth then he was still 1, making him 12 in The Last Olympian. He would’ve turned 13 in between The Lost Hero and Son of Neptune. Hazel when she died was 13, making her 13 when she came back In I believe September, when Nico was still 12. If we yet again disregard weird aging ideals then she would have turned 14 in December, while Nico was still 12, just a few weeks shy of turning 13. (Also to add into for the Frank and Hazel age thing, when Hazel turned 14, Frank was still 15).
Anyways, I’m sure theres more but these are the ones that get me ranting the most. Rick please learn timeliness and how to keep them going without mix up I beg 🙏🙏
