One common theme is redemption. Given their past actions in the game, many fanfictions explore how they can redeem themselves through their relationship with each other.
Another way is to have them open up about their pasts. Michael could share more about his family problems and how he got into the criminal life. Trevor could talk about his own traumas. By understanding each other's backgrounds better, they can become closer friends. They might start to see each other in a new light and be more empathetic towards one another. This could lead to them being more protective of each other in future situations.
A plot could revolve around them starting a new business together. Since they both have different skills, Trevor's wild and fearless nature combined with Michael's more strategic thinking. They face challenges from competitors and have to figure out how to keep their business afloat while also dealing with their personal issues.
There's also 'A Different Kind of Bond'. This fanfiction focuses on the two of them forming an unexpected friendship. It shows how they gradually come to understand and rely on each other in a really interesting way.
In the 'franklin plays the game story', Franklin is likely the main character. He could be a human being with unique traits and qualities. Maybe he is known for his competitiveness in games or his friendly nature towards other players. Without reading the story, we can't be certain about his exact identity but he is the one central to the action of playing the game.
I'm not sure who Trevor Holt specifically is in this story without more context. It could be a fictional character created for a particular book, movie, or other form of media.
I'm not sure specifically who Jon Franklin is without more context. He could be an ordinary person with a passion for sharing true stories, or perhaps a professional storyteller, journalist, or writer.
Well, it depends on how you define 'good'. Trevor Story has shown flashes of brilliance, but his consistency can be a bit up and down. However, when he's on his game, he can be a real force to be reckoned with.
