During their wedding, Percy gives his vows to Annabeth in Ancient Greek. (Because Annabeth taught him how to speak Ancient Greek in the lightning thief)

percy: my son? uh oh, that never means anything good

annabeth: your son poured a blue colored chemical in all the beakers in his honors chemistry class today, just because it was blue. and since he didn’t know what it was, it ended up causing a toxic gas to build up and the entire school had to evacuate. he has now been moved to regular chemistry, because he is not trusted to handle chemicals and labs anymore

Annabeth Chase would NOT be content with a normal, everyday life. Yes, she has Percy, yes she has her friends, yes she has her dream job, her dream home, but she does not have the adventure, the adrenaline rush, the spark in her blood as she spots a monster hiding in an alley.

Annabeth Chase craves adventure. The girl ran away from home when she was SEVEN. She has been waiting and training for years to go on a quest. She wanted to lead one too. And even after the war with Gaia, even after the trek through Tartarus, she was ready to help Magnus with his quest. She wanted to help. And I can bet you anything that the moment she got back home after Magnus explained everything, she buried herself in books about Norse Mythology. 

Unlike Percy who is shown to want a more peaceful life - lightning thief starts with ‘look, I didn’t want to be a half-blood’ and the iconic ‘why?’ when Apollo turns up in ToA - Annabeth needs battles, needs quests, needs to train and to sharpen her skills all the time. Yes, a life growing old with Percy and her children is what she would give anything to have, but along the way, she would not settle for normal. She would always be there in CHB or CJ, volunteering for quests or tracking down some particularly vicious monsters or helping younger demigods reach camp safely. 

Furthermore, she’s a child of Athena. The desire to learn more, to develop and enhance herself is in her blood. Remember the time  when she picked a fight with the Sphinx because she was being quizzed on facts and general knowledge when the Sphinx was actually supposed to ask her riddles? It annoyed her that the questions she was asked weren’t making her think.

tl:dr: Even if Percy might be willing to slowly let go of his demigod self*, Annabeth wouldn’t. 

annabeth, beaming: i made you every type of blue dessert that i could think of!

percy: oh yeah? what’s the occasion? oh crap, did i forget an anniversary?

annabeth: can’t a wife just bake for her husband?

percy, staring at her:

annabeth, staring at him:

percy, firmly: wise girl, we are not having another baby.

annabeth, frustrated: oh come on percy! why not?

percy: we’ve talked about this. we agreed to be done years ago. we have three, and they’ve destroyed half of our belongings! i mean, sure it would be fun, and i love babies and having kids with you, but we can’t just—

annabeth: if you agree to another baby, i’ll agree to another dog.

percy:

annabeth:

percy: are you bribing me into having a child?

annabeth: of course not! …why? is it working?

percy: of course not! but… keep talking.

annabeth: we can get a brand new little puppy. and you can choose both the breed and the name. maybe you can finally get that shepherd mix you’ve always wanted.

percy, rubbing his beard and thinking:

percy: you know, i’ve heard the transition from 3 to 4 kids is super easy. the little one would probably just fit right in.

annabeth: exactly. and since we’re so busy, my pregnancy will fly by. and the labor will be super fast since it’s my 4th. it’ll all happen in the blink of an eye. we’ll hardly even notice.

percy: true. then the baby and the puppy can just entertain each other.

annabeth: they’ll practically cancel each other out. and this way we’ll have an even number of kids.

percy, pointing at her: good for roller roasters.

Annabeth: you sure you don’t mind me wearing your hoodie?

Percy: it’s fine. It’s cold out and besides, you look cute in it

30 y/o Percabeth, together for almost over half of their lives:

Percy: Annabeth, have you seen my- thief!

Annabeth, wearing Percy’s hoodie: What? We share a closet

Percy: yeah but it’s mine and I want to wear it

everyone leaning in, ready for a good story:

percy: oh that would be our children
