There could be many directions for such a fanfiction. Maybe the kidnapper is someone from a past case who has a vendetta against Calleigh. Her team would then race against time to find her. They might follow clues like strange phone calls or items left at the scene.
Another motive could be that the kidnapper is a deranged fan who wants Calleigh all to himself. He might be obsessed with her and thinks that by kidnapping her, he can have some sort of relationship with her. He would likely have been stalking her for a while before making his move.
In many CSI Miami fanfictions where Calleigh gets shot, it often leads to a series of intense and emotional moments. Her colleagues would be in shock and rush to her aid. The story might then focus on her recovery process, both physically and emotionally. It could also explore how the team deals with the threat that led to her being shot in the first place.
In some fanfictions, Calleigh's pregnancy could be a source of drama. Maybe there are doubts about who the father is, creating tension within the team. Or perhaps she has to deal with health issues during her pregnancy that add to the suspense of the story. It could also be a story of her learning to balance motherhood with her career, especially in such a high - stress job like CSI Miami.
One common theme is friendship. Calleigh and Alexx are often portrayed as having a strong bond in fanfic. They support each other through the tough cases and the emotional toll that comes with their jobs. Another theme is teamwork. Their different areas of expertise in CSI come together to solve crimes, and this is often highlighted in the fan stories.
She might face physical challenges. For instance, the long hours at the crime scene or in the lab could become exhausting more quickly due to her pregnancy. Standing for long periods or carrying heavy equipment could be difficult.
They would rely on each other. Eric might be very protective, always making sure Calleigh is taking it easy and not overexerting herself. Calleigh, on the other hand, would try to stay involved in the CSI work as much as she could while also following doctor's orders. They'd also lean on their friends at the CSI Miami office. Horatio, for example, could be very supportive and make sure they have the resources they need.
One great place to find CSI Miami Calleigh Alexx fanfic is Archive of Our Own (AO3). There are many stories there that explore their relationship and adventures. Some fanfics might focus on their friendship during cases, like how they support each other in the high - stress environment of the CSI lab. Another option could be FanFiction.net, which also has a wide range of fan - created stories about these characters.
It could make them more in sync at work. Since they are now married, they might have an even deeper understanding of each other. They could anticipate each other's moves during investigations more easily.
Another plot twist could be that Eric gets injured on a case right before the wedding. He's in a coma, and Calleigh has to decide whether to postpone the wedding or hold onto the hope that he'll wake up in time. This would also bring in elements of their friends and colleagues from CSI Miami, like how they support Calleigh during this difficult time.
