If we look at it from a writer's perspective, they will stay together definitely. To break them up would be writer’s suicide. They are too popular at this point. Rick is aware of this, seeing how much more sappy Percabeth has become in the latest books. Plus, relationship wise, there is nothing that can really shake their relationship now. They’ve been through two wars together and Hell itself. Annabeth seeing Percy’s darker side might scare her but, in the end, she’ll be okay with it as one accepts their partner for who he is, warts and all.
