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.
Well, Finn could be facing an injury in football which makes him question his future in the sport. Meanwhile, the Glee club could be preparing for a big competition. Finn has to find a way to support his team both on the football field (even if he can't play) and in the Glee club, which leads to some heartwarming and inspiring moments.
Finn might be shocked at first. He could be a bit panicked, not knowing exactly what to do or say immediately. After the initial shock, he might start thinking about the future and how to support Rachel and the baby.
One possible fanfiction could be about Finn's journey in football while also dealing with the drama in Glee club. Maybe he uses football as an escape from the pressures of the club, but then realizes how much the club and his friends mean to him and tries to balance both worlds.
One great 'Glee Finn and Rachel fanfiction' is 'The Road to Stardom'. It beautifully captures their relationship growth. The story shows how they support each other in their pursuit of a career in music. It has well - written dialogues that really bring the characters to life.
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.
