A really interesting plot could be that their new - found sibling relationship causes a stir in the Glee club. Some members might be skeptical, thinking it's a ploy for more attention. Meanwhile, Rachel and Puck have to deal with the fact that they have different friends in the club. They could have to navigate through the club politics while also getting to know each other as siblings. For example, Puck's bad - boy image might clash with Rachel's more uptight personality at first, but they gradually learn to accept and even complement each other.
One plot idea could be that Rachel and Puck initially panic when they find out about the pregnancy. They might struggle to tell their friends and family, especially considering their different personalities and backgrounds in the Glee club. Maybe they decide to keep it a secret at first, but as the pregnancy progresses, it becomes harder to hide.
Maybe the arranged marriage is part of a deal to save their families' reputations. Rachel's family wants her to marry into Puck's family to gain some social standing, and vice versa. Initially, Rachel is furious as she has her own plans for stardom. Puck, on the other hand, is more laid - back about it. But when Rachel's Broadway dreams start to crumble, Puck uses his family's connections in the music business to help her, which makes her see him in a new light and begins to accept the arranged marriage.
One idea could be that they initially struggle with the news but then grow closer as they prepare for the baby. For example, Puck might start taking on more responsibilities like getting a job to support them.
There's a fanfiction where Puck has to protect Rachel from some bullies at a music event. This fic explores their relationship in a more protective way. Puck uses his tough - guy image to keep Rachel safe, and in the process, they start to see each other in a different light. Their shared love for music becomes the bond that deepens their connection.
Their relationship as siblings would likely bring a new level of loyalty to the Glee club. They would support each other more openly, which could inspire other members to be more united. For example, if Rachel was being bullied by a rival group, Puck would be more likely to step in and defend her, setting an example for the others.
Perhaps in the fanfiction, Finn and Puck find themselves in an alternate universe where being gay is the norm in the glee club. This allows them to freely explore their relationship without the fear of judgment. They could then face the challenge of how to bring this new - found confidence back to their original world.
In the fanfiction, it could be that Rachel and Puck are married and they start a music project together. However, they have different creative visions. Rachel wants a more polished and Broadway - style production, while Puck is leaning towards a more edgy and rock - n - roll approach. This causes some tension between them, but as they work through it, they create a unique and amazing musical piece that showcases both of their styles. It also strengthens their relationship as they learn to compromise and respect each other's artistic ideas.
One plot idea could be that Rachel and Will collaborate on a very unique musical production. They face challenges like budget cuts and a lack of student interest at first. But through their combined efforts and Rachel's determination and Will's teaching skills, they manage to turn it around and create a show that wows everyone.
A really cool idea for a fanfiction could be that Rachel and Finn swap personalities for a day. Finn suddenly becomes super - focused on his Broadway dreams like Rachel, and Rachel has to deal with Finn's more laid - back attitude towards things. It would be a humorous and also a great way to explore their relationship from a different perspective.
One great 'Puck and Rachel' 'Glee' fanfiction is 'Unlikely Duet'. It beautifully explores their relationship as they work on a duet together in a different setting than the show. They start to understand each other on a deeper level.
