An interesting plot twist might be that Charlie Matheson gives birth in a completely different time period or dimension. She suddenly finds herself in a historical era or a parallel universe during the labor, and has to deal with the differences in medical knowledge and cultural norms while bringing her baby into the world.
One idea could be a fanfic where Charlie Matheson's pregnancy is a time of great anticipation. Her friends and family rally around her. The story could focus on her emotional journey, from the initial shock of finding out she's pregnant to the joy and nervousness as the due date approaches. It could also include details about how she prepares for the new arrival, like decorating the nursery and taking parenting classes.
I'm not sure specifically as I haven't read that particular fanfic. It could be about Betty's experience during childbirth, perhaps the emotions she goes through, the people around her at that time, and how it changes her life.
Obviously, Ana herself would be the central character. Her partner could be an important character too, being there for her during the pregnancy and birth. Maybe her mother or a close female friend who offers advice and support.
The fanfic might focus on the actual birth. It could describe the setting, whether it's in a hospital or at home. And also the people around her during the birth, such as a midwife or her partner. There could be some tense moments and then the joy of the new life arriving.
Well, it could be about the challenges Clary faces during childbirth, like her fear and the support she gets from her friends. Maybe her partner is by her side, holding her hand through the pain.
It could be a mortal man who somehow managed to catch Artemis's eye. Maybe he was a great hunter like her, and their brief encounter led to the pregnancy.
One common theme could be the development of family relationships. When the reader gives birth, it often leads to the exploration of how the new family dynamic works, like the relationship between the reader and the partner in the fanfic, and also how they raise the child together.
There's also the possibility that it's an unknown stallion from a far - off land. Twilight could have had an adventure in a different region and met someone there. This would add an element of mystery to the fanfic, as the readers would be curious to learn more about the father's background and how he and Twilight met.
Obviously, Prowl would be the main character. There could also be her partner, if she has one. Maybe a friend or a family member like her mother or sister if that applies in the story's context.
