One common theme is the element of surprise. Since the pregnancy is often unplanned, it creates a lot of drama and tension. For example, in many fics, the OC might be worried about how Spencer will react.
The theme of protection also frequently comes up. Spencer, being the protective type, will do everything he can to ensure the safety of the OC and the unborn baby. This can lead to some really touching scenes where he shows his love through his actions, like making sure the OC has proper medical care and a safe environment.
One common theme is the exploration of Spencer's vulnerability. Despite his intelligence, the idea of becoming a father makes him feel out of his depth in many stories.
One common theme is the exploration of Reid's hidden emotions. Since he's often portrayed as a bit reserved in the show, in these fanfictions, the relationship with the OC might bring out his deeper feelings. Another theme could be the clash between his professional life and his new - found personal relationship. For example, how he manages to keep his focus on cases while being in love with the OC.
Some common themes could be the OC's struggle with illness while Reid offers his intellectual and emotional support. Maybe the OC is in the hospital due to a case - related injury, and Reid is there to solve the mystery behind it. Another theme could be the budding romance between the OC and Reid in the hospital setting, with Reid using his knowledge to comfort the OC.
One common theme is the exploration of Reid's complex personality within the context of a relationship. Since he is a very intelligent and somewhat socially awkward character, fanfictions often show how he navigates the new territory of being married to an OC. Another theme is the building of a unique bond between Reid and the OC. It could be based on shared interests, mutual understanding, or just pure attraction.
One common theme is the struggle to balance work and family. Since Reid has such an intense job at the BAU, in these fanfictions, his married life often involves trying to be there for his family while also being away for long periods on cases.
One common theme is Reid's intellectual superiority. Fanfictions often highlight how his genius mind sets him apart from others. For example, in many stories, he's the one who cracks the most difficult parts of a case.
Romance is also a big theme. Whether it's a slow - burn or a more immediate attraction, the relationship between the female and Spencer Reid is often central. For example, they might start as colleagues and gradually develop feelings for each other over time as they solve cases together. It adds an emotional layer to the usually intense and cerebral world of Spencer Reid.
Recovery is also a big theme. The fanfics usually follow Reid's journey from being hurt to getting better. This can involve his own internal processes of dealing with the pain, as well as external factors like medical treatment and the care of his friends. It often shows his determination to get back to his normal self and continue his work in the BAU.
A common theme is Reid's unique perspective. His autistic mind gives him a different way of seeing things, which often leads to him making connections in cases that others miss. For example, in many fanfics, he notices small details in crime scenes that others overlook because of his hyper - attention to detail, which is a characteristic of autism.
Another theme is acceptance. The stories often deal with how Reid's friends and colleagues accept or react to his new - found identity. It can range from full support to initial confusion and then coming around. There are also themes of love against all odds, as Reid might face challenges in a relationship with a male partner in a world that may not be entirely open - minded.
