I'm not sure if there is an official fanfiction with such a plot. It could be possible that some fans have written it, but it might not be a common or mainstream storyline within the Lemonade Mouth fanfiction community.
Yes, there are some. You can check out fanfiction websites like Archive of Our Own. Just search for 'You Joe and Beck pregnant' and you might find some interesting stories. Some of them might focus on the relationship dynamics when Beck is pregnant and how Joe reacts to it.
Another aspect of the plot could be the emotional journey. Stella might be scared about the changes her body is going through and the future of her relationship with Ray. Ray could also be feeling a lot of pressure. They would need to communicate better and learn to rely on each other more. The pregnancy could also be a catalyst for them to become more mature and make some tough decisions about their lives, all while still trying to keep their love for music alive within the context of the Lemonade Mouth story.
One common theme could be the struggle for power in their relationship. With Beck being pregnant, it might shift the power dynamics between her and Joe. Another theme could be the idea of family and how they both envision their future as a family, or not, considering Joe's rather complex personality.
A common theme is her strong - willed nature. Fanfictions often explore how she uses this to solve cases. For example, in many stories, she's up against tough criminals but her determination never wavers.
One common theme is friendship. Stella often forms deep friendships in fanfiction. For example, in many stories, she bonds with other characters over shared goals or experiences.
Another theme is discovery. Stella usually discovers the new and exciting world of Naruto. This could involve learning about chakra, different jutsus, or the complex social structure of the ninja villages. It's like a fish out of water story but in the Naruto universe.
In fanfiction, Ray and Stella can symbolize different things. Ray might represent the more stable, rhythmic aspect of the band, while Stella could be the creative and free - spirited element. Their relationship, whether it's friendly or something more, can show how different personalities can come together to create great music in the context of Lemonade Mouth.
There are countless possibilities for Stella's story. It could be inspired by her dreams, where she envisions a world different from our own. For example, a world where animals can talk and they have their own society with rules and hierarchies. Or it could be a historical story, where Stella delves into the past and writes about an important event or a forgotten hero.
