Definitely. There are fanfics that take the events from the original 'The Outsiders' and expand on them from Dally and Johnny's perspective. They might add more backstories or create new situations for the two characters. It's really interesting to see how different authors interpret their relationship and develop it in their own unique ways.
One common theme is redemption. Dally is often portrayed as a character who has made mistakes but is trying to make up for them. Another theme is loyalty, especially his loyalty to his friends in the gang.
Well, the themes in 'The Outsiders' include friendship. The boys in the Greaser gang have a strong bond. They support each other through thick and thin. Violence is also a theme. The constant fighting between the Greasers and the Socs shows how violence can be a result of social differences. And there's the theme of identity. Ponyboy struggles to figure out who he is in this world of social hierarchies.
One common theme is loyalty. Since they are part of the same gang, fanfictions often explore how loyal they are to each other, like in situations where one has to defend the other against outside threats.
As I don't have any information about the Sherri Dally story, it's really hard to point out the most important aspect. However, generally in a story, things like the main conflict, how the protagonist overcomes challenges, and the lessons learned can be very important aspects. But without knowing the details of this particular story, we can only speculate.
I'm not familiar with the Sherri Dally story. It might be a story that is known only within a certain community or family. If you can give some hints like where it happened or what kind of story it is (e.g. a heroic story, a love story), it would be easier to answer.
Perhaps it's a novel about a character who is constantly dilly - dallying while translating something. It could be a humorous take on the world of translation, where the main character's indecisiveness or slowness in translating creates all sorts of comical situations. Another possibility is that it's just a name given to a translation project that has been taking a long time to complete, so they named it in this somewhat light - hearted way.
