Well, a frequent theme is the growth of their relationship. Starting from just being coworkers in the BAU to developing a much closer bond. Also, the theme of sacrifice. In some fanfictions, they are willing to sacrifice their own safety or career for the other. Additionally, the theme of trust is common. They trust each other with their secrets, which is a big part of their relationship development. This trust is often tested in different scenarios in the fics.
One popular Spencer Reid x Emily Prentiss fanfiction is 'The Unspoken Bond'. It beautifully explores their relationship in the context of the BAU. It delves into how their different personalities complement each other during cases and in their personal lives. Another great one is 'Hidden Feelings'. This fic focuses on the slow - burning aspect of their relationship, with lots of tension and emotional moments as they gradually realize their feelings for each other. And there's 'Partners in More Than Crime' which shows their relationship evolving from just colleagues to something much deeper through various challenges they face together.
Another good one is 'In the Shadows with You'. It's a bit more action - packed. The plot involves the two of them working together to solve a complex case while also dealing with their growing feelings. The way the author writes the chemistry between Emily and the reader is really intense and makes for an exciting read.
In Spencer Reid x Derek Morgan fanfiction, the relationship between them can be portrayed in various ways. Some fanfictions might focus on their platonic bond, showing how they support each other during tough cases. Others could delve into a more brotherly - like love, where they are extremely protective of one another.
There are quite a few amazing Spencer Reid x Reader fanfictions. 'A Chance Encounter' is a really nice one. It starts with a simple encounter between Reid and the reader and then develops into a deep and meaningful relationship. The author does a great job of capturing Reid's personality. 'Love in the Shadows' is also worth reading. It has a bit of mystery in it as the relationship between the two unfolds while they are dealing with a case together.
The popularity of Emily Prentiss x Reader fanfiction lies in the allure of the character Emily Prentiss herself. She is a complex and strong - willed character from the show. Fans are drawn to the idea of creating a personal connection with her through fanfiction, which allows them to explore different scenarios and relationships.
A common trope is the 'hurt/comfort' one. For example, when Reid is in danger during a case, Morgan is always there to save and comfort him. It shows their deep bond. Another popular trope is the 'partnership in crime' sort of thing, where they work together to solve a mystery that others can't.
A common theme could be the exploration of their different personalities. Spencer Reid is often portrayed as highly intelligent and a bit socially awkward, while Eliot Spencer is more of a tough, action - oriented type. So, fanfics might focus on how they interact and learn from each other.
One idea could be to focus on how her pregnancy affects her work in the BAU. Maybe she has to deal with the physical limitations while still being determined to solve cases. For example, she might struggle to keep up during a chase but use her wits more than ever.
I really like 'Side by Side'. It focuses on their partnership during difficult cases. It shows how they rely on each other's skills and intuition. The plot is engaging and full of twists that keep you hooked from start to finish.
