A common theme is loss. Since it's about saying goodbye, there's often a sense of losing someone important, whether it's a colleague or a friend within the CSI world.
Well, I'm not sure of a specific 'csi saying goodbye fanfic' off the top of my head. But you could try looking on fanfic platforms like Archive of Our Own. Search for 'csi' and 'goodbye' tags, and you'll likely find some interesting ones. There are often fics that explore the characters' relationships during a goodbye scene in really creative ways.
One common theme is friendship. Calleigh and Alexx are often portrayed as having a strong bond in fanfic.

Their different areas of expertise in CSI come together to solve crimes, and this is often highlighted in the fan stories.
One common theme is the integration of the OC into the CSI Miami team. Usually, the OC has to prove themselves and find their place among the established characters, like Horatio. Another theme is the solving of complex crimes. The OC often brings in a fresh perspective that helps Horatio and the team in their investigations.
One common theme is the idea of the characters using their 'ability' to see ghosts to solve cases in new and unexpected ways.
A common theme is the clash of different forensic techniques. CSI Miami often deals with outdoor and water - related evidence more, due to its location, while CSI NY has to handle evidence in a more urban and high - rise environment. In crossovers, they have to find a way to combine these methods. For instance, when dealing with a crime scene that has elements of both cities.
A common theme is the mentorship. Horatio often acts as a mentor to Jess in many fanfics. For example, in some stories, he teaches her how to handle the tough situations in the CSI Miami environment.
A third common theme is mystery. Just like in the CSI Miami show itself, the fanfics usually revolve around solving some sort of mystery or crime. The niece might be directly involved in the case, or she could be a side character who is affected by the events. There's also often a bit of drama, whether it's between the niece and other characters on the team, or related to the mystery at hand, like secrets being uncovered that impact the story's progression.
One common theme is family. Writers often explore the relationship between Horatio and his daughter, showing how they support each other through difficult times in the CSI Miami world. For example, his daughter might be in danger because of his job, and the story could revolve around how he protects her.
Common themes in CSI pregnant fanfiction often include the fear of how pregnancy will affect the character's standing in the CSI unit. There's also the theme of the character's changing relationships. For instance, her relationship with her partner might become stronger as they prepare for a new life together, or it could be strained due to the added stress. Additionally, the theme of the character adapting to her new physical state while still being in a dangerous and demanding job is quite prevalent.
One common theme is the mending of broken relationships. In these fanfics, characters who had conflicts or lost trust in each other find ways to reconcile. Another theme is self - discovery. As the characters work towards trusting again, they often learn more about themselves. For example, they might realize their own insecurities that contributed to the lack of trust in the first place.
