The main characters are Finn and Rachel. Finn is often portrayed as a bit of a jock with a big heart, and Rachel is the extremely ambitious and talented singer. In the context of the pregnancy fanfiction, they are the couple facing the life - changing event of having a baby.
In addition to Finn and Rachel, other characters from the 'Glee' universe might also play important roles. For instance, their friends in the glee club could be there for support, like Kurt who might offer fashion advice for baby clothes or Mercedes who could give Rachel advice on handling the physical changes during pregnancy. Also, the teachers like Mr. Schuester might have an impact on how Finn and Rachel handle the situation, perhaps by providing some life lessons or practical help.
Another plot might be their journey in preparing for the baby. This could include things like Rachel having to balance her dreams of stardom with impending motherhood, and Finn trying to find a stable job to support the family. They might also face challenges in their relationship as the stress of the pregnancy mounts.
Finn and Rachel are the main characters. Finn, who has his own insecurities and strengths, and Rachel, who is used to being in the spotlight. In the fanfiction about their pregnancy, they are the ones whose lives are being turned upside down. Their individual personalities and how they interact with each other during this time are what drive the story forward.
Overcoming obstacles is also a major theme. It could be dealing with rivalries within the glee club, family issues, or problems in their relationship. For example, some fanfictions focus on how they deal with jealousy when one of them gets more attention or a better opportunity. Also, friendship within the glee club context while maintaining their relationship is often explored.
Typically, the main female characters from Glee like Quinn Fabray are often involved. She had her own experience with teen pregnancy in the show, so she would be a natural fit in such fanfiction. Also, characters like Santana Lopez and Brittany Pierce might be included as they are Quinn's friends and are also part of the female group in the glee club.
