As toxic as Percabeth is, they’re still teenagers and there’s a chance that they could grow past that and Annabeth would overcome it. Heroes of Olympus makes that feel unlikely though.
I hold that belief because my relationship with my spouse started out unhealthy- I was extremely codependent due to not having many friends growing up and never quite getting the emotional support I needed from my family. But we grew past that and 11 years later, we’re approaching our 7 year marriage anniversary with our biggest goals as a couple (besides raising our kids) is to always communicate and it’s working well for us.
Annabeth in particular never maturing and growing past it doesn’t have to be what happens. They’re still teenagers, she could grow past it.
Unfortunately, she doesn’t seem like she’s going to grow and so many people act like the toxic relationship they have is normal and I’m just like…. No. Never mind, I don’t want to read Percabeth. Maybe I’ll ship Percy with Apollo or no one then.
I also thought of it that way. Annabeth would mature and come to understand the error of her ways, and since Percy means so much to her, she would reflect on all the things she says and does and change her ways in order to pursue a more healthier and long lasting relationship.
Then I read the Chalice of God and Read.Riordan. entries, and lost all hope. Annabeth is a character that you think cannot devolve more, and she surprises you in the worst possible way.
I have completely given up on Percabeth, and I will be reading any incoming books just for Percy as I always do.
Perpollo is a new but great ship that has so much potential but I am not really too in it yet but at least due to Apollo, Percy might ascend to godhood which is something I think is inevitable for someone of Percy's stature and power.
Right now, I think I am all for Perachel only. It's the best possible ship for Percy and for Rachel, and if you are interested, you should check out those posts.
But seriously, between their shared prophetic abilities, creative quick thinking minds, fun and easy going personality, and a deep care and affection for each other, Percy and Rachel are literally meant to be.
The Spirit of Delphi is extremely ancient and free and given Oracle of Delphi was once in Poseidon's domain, she could change alliances and freely date Percy, but my favorite headcanon is that Percy becomes a God and Rachel decides to swear allegiance to him instead.
Also, if you have any Perpollo recommendations or posts to share, please do.
