Chapter Text
Third Person POV
“You broke the oath!”
The king of the gods rages at his brother, who merely raises an eyebrow at him.
“I did not.”
Zeus glares.
“The proof of your broken oath stands right behind you! Unless you claim this child isn’t yours?”
The sea roars, feeling its master’s rage as his trident appears in his hand.
“I do not deny that Perseus is my son. I can, and have, claimed him as my own before my court. To touch him would be an act of war against the Sea, brother. And-“ the sea god’s eyes flash dangerously “-you know that is not a war you will win.”
Flustered, Zeus panics for a moment before he shakes his head and steps forward.
“Regardless of your claim upon him, your child is still of a broken oath!”
Poseidon lets out a long sigh, running his hand down his face in a very human gesture.
“No, I did not. If you remember, the wording of the oath was ‘We, the sons of the Titan King and Queen, swear to no longer have demigod children.’”
Zeus rolls his eyes.
“Yes, Poseidon, I know very well the wording of the oath. But I fail to see-”
Clearly having reached the end of his patience, Poseidon slams the butt of his trident on the ground, and Zeus stops.
“Children, Zeus. Children. Perseus is my only demigod son. Hades has had no children since before the oath. You, my dear brother, are the only one to have broken the oath.”
Percy tilts his head, confused.
“But, Bampas, Lord Zeus only has Thalia?”
Posiedon ruffles his son’s hair gently.
“Yes, Zeus only has one child. However, Thalia Grace is not the only child of the Sky King.”
Posiedon’s form shifts to that of a stricter, more militant one. His clothes change too, from khaki pants and a pale blue button-down to what Percy somehow knows is the uniform of a lighthouse keeper.
“Do not try to pretend Jason does not exist, brother mine.”
The god is speaking in a language that Percy instinctively knows he should not be able to understand, but he does.
Zeus, whose form has changed to a stern-looking man in a dark purple toga, grits his teeth.
“Jason Grace is my son, not Zeus’s.”
The other god, the one who looks like his dad but also not, gives the not-Zeus a shark-like grin.
“The oath said ‘sons of the Titan King and Queen’, which does not specifically point to either Greek or Roman.”
Roman.
The God of the Skies-Jupiter, if Percy remembers his myths correctly, frowns.
“Jason was not a thought in my counterpart’s mind when Thalia was sired.”
There’s a flash of light in the room, and the three women from the fruit stand are in front of the gods.
“Atropos, Clotho, Lachesis, this is unexpected.”
The one holding the distaff-Clotho, Percy remembers-rolls her eyes at Jupiter.
“Perhaps a second child was not a conscious thought, but do not deny that you and your counterpart had plans to see Beryl Grace again after Thalia’s birth. Yes, son of Saturn, we knew you would have children. Had Zeus had only Thalia, the oath would not have activated, and she would be alive now, having just reached the age of sixteen, and the Great Prophecy would be upon us. But because you planned to see Beryl Grace again, because you had Jason, Styx took her revenge.”
Atropos cackles, a throaty, unnerving sound. “If not for the actions of Poseidon, Thalia Grace would be dead now.”
Lachesis pins her gaze on the Sky King.
“The God of the Seas did not break the Oath. But you, Sky King, you did.”
Atropos looks at him one last time before she vanishes with her sisters.
“The consequences of breaking the oath fell on your daughter, and they will fall on your son in time. And there's nothing you can do to stop that."
