Unpopular Percy Jackson Opinions:
Reyna and Jason had such an insane amount of potential storyline where Jason could have understood he has been in love with Reyna before Hera erased his memories as the story progressed, and Piper discovering she is into girls would make more sense too. The storyline we got was a complete and utter waste of Jason's character.
Given that, I do think Reyna should have ended up with Thalia because doomed lovers and ex-situationship with her brother tropes would go so hard, also because it would be the only saving grace of the absolute shit decision of Reyna joining the hunters.
Nico is the one who always struggles with his morals and questions most if he is a bad person in the books, but Percy is actually the one that has the most grey morals out of all characters. Everything Nico has a dilemma inside fearing he is a bad person, Percy stayed in a position to do it or at least thought to do it without hesitation.
Luke developed romantic feelings for Annabeth, yes it was very disturbing and completely disgusting, but it happened, and that actually makes the foundation of the main conflict between Percy and Annabeth in BOTL and TLO, and I hate it when people act like this never happened and try to enforce that he only thought of her as his sister. It was twisted and gross but disregarding this takes away from Luke's character too because in the end, he actually became a horrible person and he accepted to die because he realised that in the end. Silena was also a minor when he started manipulating her sexually, why is this not ignored but his disgusting feelings for Annabeth is?
There is no way Percy's highly suicidal feelings went away on their own because in the new books it is obvious he doesn't talk about his feelings, especially to Annabeth. And this will blow up very badly if he keeps shoving the feelings down, but it is obvious Rick will not give ANY emotionally depth storylines in the last book because for some reason he lost the ability to write deeper scenes with deeper feelings.
I still can't believe that the Percy that went all berserk on Nico because he betrayed him in TLO and whose only line that can't be crossed is betrayal and stabbing in the back didn't go crazy the moment he saw Calypso again because of the curse she put on Annabeth and confronted her properly. That was probably the most out of character thing he did.
