Often, there might be themes of acceptance. Since Booth being gay is a departure from the original character in the show, the fanfic might focus on how he is accepted or not by the other characters. There could also be themes of self - discovery. Booth may have to come to terms with his new - found sexuality and how it fits into his life as a whole. This could involve him dealing with his past relationships and how they now seem different in light of his new identity.
Sorry, I'm not really into that specific fanfic genre, but you can try searching on some popular fanfic websites like Archive of Our Own. There are likely many works related to it there.
One common theme is their relationship development. Writers like to explore how their feelings for each other grow over time. Another theme is mystery - solving together, but with different twists compared to the show. For example, they might solve a mystery that has a personal connection to one of them.
Love and relationship development are common themes. It often explores how two male characters with a connection (related to the 'bones' context) fall in love and deal with various relationship issues.
Family is a very common theme. It shows how Bones and Booth's family expands with the arrival of the baby and how they adapt to their new roles as parents. Another common theme is the continuation of their relationship in a new phase. They have to balance their love for each other with the responsibilities of raising a child.
Love and longing are common themes. Most fanfictions explore the pent - up feelings that Bones and Booth have for each other before the kiss. It shows how they've been dancing around their relationship for so long.
Another common theme is the way their relationship evolves during the time of hurt. It could be that the hurt brings them closer together. For instance, Booth's injury makes Bones realize how much she truly cares for him on a deeper level, not just as a colleague. And vice versa, Booth might see Bones in a new light when she is the one helping him through a difficult time. This exploration of their relationship under stress is a central part of many Bones Booth Hurt fanfictions.
The theme of family values also pops up a lot. The fanfictions might show how their families (both Booth's and Bones' extended families) react to the new baby, and how they all come together to support the new little family. It's about the importance of family and the new family unit that Booth and Bones create with their baby.
Love and loyalty are also big themes. Booth's protectiveness is a sign of his deep love and loyalty towards Bones. In these fanfictions, it's often shown that he would do anything for her, which is a strong display of his feelings. For example, he might sacrifice his own safety or career opportunities to keep her safe. The relationship between them is central, and his protection is a key aspect of that relationship.
Good Booth and Bones fanfic often has strong characterizations. It stays true to the personalities of Booth and Bones from the show. For example, Booth's protective nature and Bones' scientific mind are usually well - represented. Also, a good plot is key. It might involve an interesting case or a new development in their relationship.
I'm not sure specifically as there could be many interpretations. It might be a fan - created story where a character named Booth saves Bones, perhaps in a situation like a dangerous crime scene or some sort of life - threatening event in the context of the 'Bones' series.
