Jess performs some tests, and concludes that Cody is turning into a mermaid -- or rather, a merman. Turns out that his mother is a mermaid, and he will eventually transform altogether.
In spite of the "keeping my secret" hilarity, the movie is rather disturbing. The transformation is painful and traumatic, and when it is complete, Cody will no longer be human. He must abandon his human friends and seek out "his own kind" in the ocean.
But there's substantial gay content, and not just the endless swimsuit shots.
2. None of the main characters other than Cody express any heterosexual interest. They all seemed extraordinarily focused on him.
3. The "fish out of water" looking for a place where he can be himself. Ok, gay symbolism.
Chez Starbuck hasn't done much acting since The Thirteenth Year. He played a jock in Time Share (2000) and got undressed in the MTV series Undressed. He appeared as himself in the reality series The Real L-Word (2011), about real lesbians, and for some reason made a plaster cast of his penis.
