Their relationship would likely become more serious. With a baby on the way, they'd have to start thinking about long - term plans. They might argue more about things like finances and living arrangements. But at the same time, they could also grow closer as they experience the joys and scares of pregnancy together.
One idea could be that they struggle with how to balance their dreams and the new baby. For example, Rachel might be worried about her Broadway career being put on hold. Another could be that they face judgment from their friends in Glee club. Maybe some think they are too young or not ready. And a third plot idea could be that they discover some family secrets during the pregnancy that add more drama to the story.
A great fanfiction idea could be a 'what if' scenario. What if Brody had stayed in Lima with Rachel instead of going to New York? How would their relationship have developed in the more familiar and less competitive environment of Lima? It could explore their relationship within the context of the small - town charm and the existing relationships with the other Glee club members.
You can try fanfiction websites like Archive of Our Own (AO3). It has a large collection of fanfictions on various topics, including Glee, and specifically about Rachel and Brody. The site is well - organized, and you can search by tags to find exactly what you're looking for.
One great fanfiction about Puck and Rachel being pregnant in Glee could be 'A New Beginning'. It focuses on how they deal with the unexpected pregnancy and the reactions from their friends and families. They face challenges like school and their future dreams, but also find a new level of closeness through it all.
One possible fanfiction could be about how Rachel deals with her pregnancy while still trying to pursue her dreams in the Glee club. Maybe she has to balance rehearsals and performances with doctor appointments and the physical changes she's going through.
I'm not entirely sure if there is a specific fanfiction with exactly that plot. 'Glee' has a large fanfiction community, and they come up with all sorts of ideas. It's possible that someone has written a story where Rachel is pregnant by Mr. Schuester, but it also might not exist. You could try searching on fanfiction websites to find out for sure.
Another option could be Jesse. Their relationship was also quite intense. Jesse has his own ambitions in the world of performing arts, and a pregnancy with Rachel would create a huge conflict for him. He might be torn between his love for Rachel and his career goals, and this could lead to some really dramatic storylines in the fanfiction.
The main characters are Rachel and Finn. Rachel is a very ambitious and talented singer in the Glee club, always striving for the spotlight. Finn, on the other hand, is a popular football player who also has a passion for singing in the Glee club.
Another option could be Puck. They had a bit of a history in the show. In the fanfiction, they could have reconnected in a moment of passion and now she's pregnant. This would surely stir up a lot of emotions among the other Glee club members, especially those who were close to both of them.
