One idea could be Finn getting a bad case of the flu right before a big performance. His friends in Glee club would then have to figure out how to cover for him or help him get better in time. Another could be that Finn has an ongoing illness that he's been hiding from the club, and it finally starts to affect his ability to participate fully. Maybe he faints during a rehearsal, and then everyone rallies around him to support him through his sickness.
One common theme is friendship. Since Will is a teacher and Finn is a student, their relationship can be explored in terms of mentorship and friendship. Another theme could be their shared love for music within the Glee club setting.
Some fanfictions might show the characters crying a lot and being unable to focus on their normal activities like singing in the glee club. They could be constantly thinking about Finn and having flashbacks to their memories with him.
There are many talented writers out there. Some of the well - known ones are often those who have been writing in the Glee fanfiction community for a long time. You can usually find good ones by looking at the top - rated stories on fanfiction platforms. But it's really subjective as different people like different writing styles.
There's a fanfiction called 'Finn and Kurt: Brothers in Harmony'. It delves into their brotherly bond by depicting how they handle differences in their musical tastes while still remaining close. It also has some really heartwarming scenes where they stand up for each other against bullies at school.
One common theme is self - discovery. Finn and Emma are both characters with their own insecurities and issues, and a lot of fanfictions explore how they grow and learn more about themselves through their relationship.
One common theme is friendship. Quinn and Finn have a complex relationship on the show, and in fanfiction, it's often explored in terms of a deepening friendship. Another theme is self - discovery. They both go through a lot of personal growth in the series, and fanfiction continues this journey, like how Finn discovers his true passion outside of football or Quinn finding her place outside of the Cheerios.
