A great fanfiction could be set in an alternate universe where they are not in the CSI field. For example, they could be teachers in a school for forensic science. It would be interesting to see how their personalities interact in this new scenario and how their relationship might grow.
One interesting story could be about their first encounter in a different setting, like at a scientific convention instead of at work. It could explore how their initial attraction might have developed in that context.
There might be a fanfiction where Grissom and Sara solve a mystery during their vacation. This would show their professional skills in a more relaxed and unexpected situation, and also deepen their relationship as they rely on each other outside of work.
