Okay, I was reading The Sea is Wine Red by gotham_girl, and I love it, but I have an idea for an AU of an AU. Percabeth pregnant when they time-travel. HERE ME OUT.
First, if Percy and Annabeth don't already know, Poseidon is either going to try to hide it from Percy because this woman totally baby-trapped him, or be like hey your gf is pregnant... why are you trying to escape? And in Annabeth's case, she has no idea until her mom shows up YOU CAN'T CHALLENGE AGAMEMNON YOU'RE PREGNANT while Odysseus and Diomedes are just standing there like🧍 (but also they are 120% against a pregnant daughter of their goddess going out to the battlefield. They will be so overprotective). Annabeth is... ◉ _ ๏ dumbfounded. This starts a vicious custody war. Between Poseidon and Athena, of course. Percy and Annabeth are 100% in favor of reuniting. There are bets on Olympus whether this baby is a boy or a girl. Apollo has to deal with Percy chasing after him, begging him to answer pregnancy questions, and frantic prayers to Artemis to assist Annabeth. Ares has not seen Percy dedicated until this kid. Percy is focused. He is terrified and so scared, but he will protect his kid. He plans like it's war. He's begging for protection for this kid. He will do anything, and yet it's tragic, because he's terrified. He's waking up asking for Apollo to check if Annabeth's okay, because he can't. Annabeth is also scared. Annabeth feels abandoned and hates the gods (just a bit). She's planning, planning, planning. She's dealing with the jeers of the Greek army because she's not married. She wants Percy and knows he wants her. She is so scared for her child.
And then the kid is born. I imagine Poseidon relents and brings Percy to the Greek camp. Everyone is wary of him, Achilles is seething, the greek kings are shutting up fast. And then this warrior, the only person who can match your best soldier, the man escorted by a god, a demigod, sees Annabeth and his child and runs to them, falling to his knees before them. He's sobbing, she's sobbing. They're hugging and cradling their child to their chest while they tell each other they love each other in English. The greek kings see the woman they looked down upon, and then see the warrior they all fear looking up at her like he's worshipping her. They're talking about names. If it's a daughter, I can see Sally, or Adraine (happy ending), or even Penelope thrown around. They are fully in their own head. The gods are around them, the greek kings are around them, and they are just staring down at their child in awe.
They are forced to coparent. Poseidon really doesn't want to, but he gets the sense this is one area his son will kill for. Everyone has to deal with some of the most powerful people on their side trade a kid, and are more loyal to each other than their sides. Already, stories/songs are spreading of their tragic love. They will be the star-crossed Romeo and Juliet in the Iliad. They will dominate Tumblr in 4000 years. Every month, Percy feeds his baby goat milk and misses Annabeth. And he would be so attractive as a father. He will do all the changes, all the night feedings himself, because he only trusts Annabeth with his kid. He's raising the standards of Trojan women. And Annabeth's going to war meetings with spit-up in her hair and a baby on her chest, but don't you dare laugh or else she and the baby will both stare and make you feel insignificant. She knows all about their stories and their history. If they make one remark towards her child, she will use that. Secretly, they had doubts she was really a child of Athena. Those doubts are gone. She is tired, scared, alone, and a mother. She WILL stab.
Like, imagine the Greek camp is attacked, and Annabeth runs to the water and drowns her newborn. Just holds them underwater while Odysseus and Diomedes are screaming, but she's saying go to Daddy, go to Daddy, and the river carries a baby who just wants his dad to Percy, who takes the baby out of the water and starts screaming for Annabeth. Or the two of them fighting on opposite sides until a monster attacks, and they both think about their child. You haven't seen them fight until they want to protect their child. They are monsters. Suddenly, they are fighting together like they have been for years. Annabeth is the eye of a hurricane and moving through the rain/water like she's done it before. Percy is the hurricane. God help them if one of the sides wants to keep the child. They will hold their child with corpses around them, laughing and crying and kissing their child and each other, while the rest of the war stands still, every soldier realizing that a war between mortals and a war between gods are very different things, and that that baby is off limits. It is the only thing that Troy and Greece can agree on.
