One possible storyline could be Blaine's struggle to balance his fatherly duties towards Colin and Archer while also dealing with his own past experiences in the Glee club. Maybe he wants his sons to have a better musical experience than he did.
He might interact with Mr. Schuester, asking for advice on how to encourage his sons' musical interests. Mr. Schuester could offer some old - school methods that Blaine might be hesitant to use.
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.
I'm not sure if there is specifically 'glee blaine abused' fanfiction. Fanfiction can cover a wide range of themes, but abuse is a very serious and often disturbing topic. The 'glee' fandom generally focuses on more positive aspects of the characters' relationships, like friendship and romance, so it might not be a common type of fanfiction within the fandom.
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.
If there is such fanfiction, it could be very disturbing for the fans of the show. Blaine was a popular character, and seeing him in an abused context goes against the positive image he had in the series. It might also make some fans uncomfortable with the fanfiction community as a whole, as it's not something that aligns with the general feel of the 'glee' show.
One great 'glee blaine and sam fanfiction' is 'The Road to Redemption'. It beautifully explores their friendship and how they support each other through tough times at McKinley High. The story has a lot of heartwarming moments that really capture the essence of their characters.
A fanfiction might explore Blaine and Ryder in an alternate universe where they are the only two openly gay members in the school. They form a strong bond as they deal with the difficulties of being different in a somewhat unaccepting environment. Their relationship becomes a source of strength for both of them as they navigate high school life.
I'm not really familiar with this specific 'mstty gkee' fan fiction. But if Blaine is Colin's father in it, he could be a character with many interesting traits. Maybe he has a heroic side, like protecting his family from some sort of danger in the fictional world. Or perhaps he has a special skill or power that is important for the story's plot.
Friendship is a very common theme. Many fanfictions build on their pre - existing friendship from the show and take it to new levels, whether it's a deeper emotional connection or a more complex relationship.
