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.
Finn's sickness can be a great way to develop his relationship with his family in fanfiction. His mom could be overly protective, and Finn might initially resist but then realize how much she cares. His step - dad could also show a more fatherly side, taking time off work to take Finn to the doctor. This family dynamic can add depth to Finn's character and show how his sickness affects those around him, which in turn affects their relationships with him.
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.
One popular Glee Blaine sick fanfiction is 'Under the Weather'. It beautifully portrays Blaine being sick and how the other characters, especially Kurt, take care of him. The story focuses on the tender moments between them during his illness.
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.
Another option is Tumblr. There are many Glee fanfic blogs on Tumblr. You can search for tags like #Glee #Blaine #sickfanfiction. Some bloggers also post links to their own fanfictions or recommend ones they've read. However, the search on Tumblr can be a bit more hit - or - miss compared to the other two platforms.
I'm not sure about its popularity. It could be popular among die - hard Glee fans who are interested in exploring different storylines and character interactions. But without specific data on views or readership, it's hard to say for sure.
