while the stables scene is a great example of percabeth's growth as a couple, particularly regarding their switch of roles in who plans for their future. an even better example is when they first told the other they loved them. annabeth, who is a well-respected strategist due to how well she can plan for the future, tells him as quickly as possible before something or someone could take him away from her again. she seized the first opportunity she had free of plan. percy, on the other hand, who is known for his impulsiveness and reckless planning, tells her two books later. not because he wasn't head over heels the entire hoo series. but because he was planning for the right moment. he wanted to wait until he could give her permanence and stability on a silver platter because he knows how much it means to her.
