It would create a lot of gossip and intrigue. Gods like Hera, who is known for her jealousy and her role in upholding marriage, would be appalled. She might try to plot against them. This could lead to power struggles within the gods' society. The younger gods might look at their relationship as a form of rebellion against the old rules. And it could also have an impact on how the gods interact with mortals. For instance, if Aphrodite and Poseidon are together, they might use their combined influence to change the way love and the sea are perceived by mortals, which could go against the traditional ways the other gods have set for them.
The relationship would be a major disruption. Mortals often look to the gods as examples of proper behavior. With Aphrodite and Poseidon in a relationship, it would shatter that perception. This could cause the gods to reevaluate their own relationships and rules. The nymphs and other minor deities associated with Aphrodite and Poseidon would be caught in the middle. Some might lose their status or protection if the relationship causes a rift. Also, it could lead to new alliances forming among the gods. For example, gods who are more liberal in their views might side with Aphrodite and Poseidon, while the more conservative ones would form an opposing group.
If Poseidon and Athena kissed in a fanfiction, other gods would likely be shocked. For example, Zeus, being the king of the gods, might see it as a threat to the established order. He could try to separate them or punish them to maintain his control. Hera, who is often jealous and protective of her position, would also be likely to oppose their relationship.
Poseidon could be depicted as a somewhat lonely god. Despite his power, he lacks the warmth and connection that Aphrodite represents. His encounters with Aphrodite could be a way for him to explore his softer side. Aphrodite would be portrayed as a confident and alluring goddess. She would be in control of her own actions and decisions, and her relationship with Poseidon would be a balance between her own desires and the expectations of the divine world.
One possible plot could be a love triangle involving Poseidon, Aphrodite and another deity. Maybe Aphrodite catches Poseidon's eye, but she is already in a relationship. Their interactions could be filled with tension and secret glances. This could lead to a series of events where they have to hide their feelings from the rest of the pantheon.
Their marriage would likely cause a stir. The power balance among the gods could shift. For example, Aphrodite's influence might increase as she is now associated with a powerful demigod like Percy. Other gods might feel threatened or might try to use their relationship for their own gains.
Their relationship would surely shock the mythological world. Since Poseidon is a major god and Medusa was turned into a monster by Athena, their love would go against the established order. Other gods and goddesses might see it as a threat to their power and status. For example, Athena would be enraged as she had a strong dislike for Medusa already.
Perhaps a plot could revolve around a love spell gone wrong. Aphrodite, being the goddess of love, might accidentally cast a spell that affects Poseidon. At first, he is angry about this intrusion into his will. But as the spell's effects make him see Aphrodite in a new light, he starts to question his own feelings. They could then be forced to deal with the consequences of this unexpected situation, not only among the other gods who might be watching and gossiping but also in terms of how it changes their relationship with the mortal world. For instance, their combined powers could cause strange weather patterns and erratic behavior among the mortals in love, and they would have to find a way to reverse the spell while also exploring their new - found feelings for each other.
Some characters might see it as an opportunity. For the Aphrodite cabin, they would be delighted as it would bring them closer to Percy, who is a powerful and respected demigod. However, characters from other cabins, especially those who have rivalries with the Aphrodite cabin, would be suspicious and might try to break up the relationship. They could think that Aphrodite is using Percy to gain an advantage in the power dynamics among the demigods.
The relationship can start with Sally having a dream about Aphrodite. This initial encounter in the dream world can pique Sally's curiosity. Then, in the real world, she starts to notice small signs of Aphrodite's presence, like finding roses in unexpected places. As she starts to explore more about Aphrodite, she could visit ancient temples dedicated to the goddess. This would show her dedication and interest, and Aphrodite could start to communicate with her more directly.
It can be developed through communication. For example, Hephaestus could finally open up to Aphrodite about his insecurities regarding their relationship. Aphrodite, in turn, could be honest about her own feelings and desires. This exchange of honest words could break down the barriers between them and lead to a closer bond.
The other sea deities would likely be excited and perhaps a bit envious. Some might offer gifts and blessings for the unborn child. The mermaids and mermen could start preparing grand celebrations in anticipation of the new addition to the underwater royalty.
