Perhaps a fanfic where the OC is in danger and Horatio and Jesse have to work together to protect them. This could show the loyalty and determination of both Horatio and Jesse. The OC could be a witness to a major crime syndicate's activities. Horatio's calm leadership and Jesse's more impulsive but brave nature would create an interesting dynamic as they fight to keep the OC safe.
One idea could be a story where Horatio and the OC meet through Jesse. Maybe the OC is a forensic expert new to Miami and Jesse introduces them to Horatio. This could lead to a series of investigations where they all work together and gradually form a deep friendship.
A possible plot is that the OC is a journalist who is covering a big story in Miami. They cross paths with Horatio and Jesse during their investigations. The OC starts to get too close to the truth of a dangerous case and Horatio and Jesse have to decide whether to trust the OC or keep them at bay. As the story unfolds, they all realize they need to work together to expose the real criminals.
One possible scenario in this fanfic could be that Horatio is desperate to rescue his niece. Jesse might get involved, using his skills from OC to help in the investigation. Maybe he has some unique insights into the kidnapper's motives based on his past experiences.
There are often fanfics that explore the backstory of how Horatio and the OC became like brothers. Maybe they started off not getting along, but through a series of events, like facing a common enemy or working through a personal crisis together, they grew closer. A fanfic could focus on that journey of their relationship evolving into a brotherly one.
A plot could be that the kidnapper is someone with a grudge against Horatio. Jesse and Horatio's team in CSI Miami follow the leads. Jesse has some knowledge about a similar case in OC. He shares this with the team, and they use it to figure out where the hostage might be held. They eventually find the location and rescue Horatio's niece.
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 possible fanfic could be about Horatio's niece coming to visit him in Miami. She might get involved in one of the cases in an unexpected way, like she witnesses something related to the crime that the CSI team is investigating. This could lead to a series of events where Horatio has to balance protecting her and solving the case.
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.
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 plot could revolve around the OC being a former criminal who has turned their life around and now wants to help Horatio solve crimes. There could be a lot of tension as Horatio is initially skeptical but then realizes the OC's value. Maybe there's a case where the crime is related to the OC's past and they have to face their old demons while working with Horatio. Also, a plot where the OC is a forensic expert from another country and brings a different perspective to Horatio's cases in Miami.
