I'm not extremely familiar with this particular fanfic type, but generally in gay fanfics, themes like friendship evolving into something more, self - discovery in terms of sexuality, and dealing with acceptance in the face of potential prejudice could be common.

For example, a fanfic could have Shadow and Silver discover a new form of Chaos energy that changes the power balance in their world.
