One of the things I wanted to do with my current Bummarry is having both, Harry and Ben, fall in love with Uma for who she really is in every way. That includes her physical form as a sea witch. That they must commit to the limitations that this implies (that she cannot transform in a human form when she goes to the island or that they cannot breathe underwater, leaving them with very limited places to interact). First, because I don't feel like there is enough content with Uma in her non-human form.
And second, because people fantasize a lot about the romance of mermaids with humans. But let's face it, the mermaid image is very conventional. Very... Delicate. But... The image of an octomaid? That is powerful. Disney used this representation for Ursula (and Morgana) because it screams power and dominance. Because a woman with eight limbs that scream phallic form is here to destroy the patriarchy. And yeah, a dominant woman is often associated by the Media with villainy.
So I wanted every encounter in my fic (at least the first ones) of Uma with Harry and Ben to be in this clear difference. Not only that she is an AK and they VK. Or that she is a goddess, Harry is human and Ben is a "fairy". Rather, they are different from where they belong. The sea and the land. They have to compromise.
And of course, in my fic, Uma was raised to know that her appearance is associated with Ursula and Morgana, that being a sea witch gives the impression that she is dangerous, so she has always had to be regal but also not promote those stereotypes. They taught her that instead of teaching others not to discriminate against her. So Uma always is very aware of her actions in her true form. But on the island, where the villains are the leaders, all those characteristics would make her stand out in a positive light. So for Harry and Ben, Uma is no different, they grew up with other sea witches (daughters of Morgana, they excellent with the violin). So Uma is more comfortable with Harry and Ben. Being in her sea witch appearance that she considers more hers. Despite the technical difficulties that all this implies.
Well... This is just an idea.
In the end, what I mean, I need more content with Uma in her octomaid form. And I know that Harry and Ben support me 100% in this.
