One possible plot could be Percy discovering his true parentage as the son of Amphitrite. He might struggle with his identity, as he has always known Poseidon as his father. This could lead to a journey of self - discovery where he has to learn about Amphitrite's powers and how they are now a part of him.
Perhaps a plot where Percy has to deal with the politics of the underwater world. Since Amphitrite is a powerful figure in the sea realm, Percy might be thrust into situations where he has to mediate between different sea factions. His relationships with his half - siblings from both Poseidon and Amphitrite could also be explored, and how they all work together or against each other in the face of underwater threats and power struggles.
One common theme is family. Since Percy is the son of Poseidon and Amphitrite is Poseidon's wife, it often explores how Percy fits into this new family structure. Another theme is power.

One possible plot could be Percy's struggle with his dual heritage. He might be conflicted between the gentle, love - associated nature of Aphrodite and the powerful, tempestuous nature of Poseidon. He could be an outcast among both the children of Aphrodite, who are often more focused on beauty and charm, and the children of Poseidon, who are known for their strength and connection to the sea. This internal struggle could form the basis of a great adventure as he tries to find his place in the world of demigods.
A great plot could revolve around Percy's role in the power dynamics among the gods. As the son of Hera and Poseidon, he has the potential to shift the balance.

They bond during lessons on sea - based powers and how to control the tides. As their relationship grows, Percy becomes more respected in the underwater world, and Amphitrite gains a new perspective on the half - bloods through Percy.
One possible plot could be Percy struggling with the duality of his parentage. He might face discrimination from both the children of Hades and Poseidon. For example, the children of Poseidon could see him as a threat because of his connection to Hades, and vice versa. He could then go on a journey to prove that his dual heritage doesn't define him, but rather gives him unique powers to protect the world of the gods and mortals.
One possible storyline could be about their journey towards parenthood. Poseidon might be shown as being overprotective of Amphitrite during her pregnancy. He could use his powers to create a safe and comfortable environment for her in the underwater realm. For example, he could make a special grotto filled with magical sea plants that emit a soothing glow and provide healing properties to keep her and the unborn child healthy.

He could be more in tune with the politics and hierarchies of the underwater world, and perhaps have a more regal bearing. He might also have a special relationship with sea creatures that are more closely associated with Amphitrite, like certain types of sea nymphs or powerful sea monsters.
