A big theme is also the pursuit of dreams. In some fanfictions, either Leonard's scientific career goals or Penny's acting aspirations are shown as part of their relationship. They support each other in achieving these dreams, and sometimes there are conflicts arising from their different career paths that need to be resolved.
Love and misunderstandings are also very common. There are many fanfictions that revolve around a misunderstanding between Leonard and Penny and how they resolve it. And of course, family. Sometimes the fanfictions include their families and how that impacts their relationship, like Penny's family coming to visit and how Leonard copes with it.
One common theme is their relationship growth. Fanfictions often explore how they develop from just dating to a more committed relationship. Another theme is their interactions with friends. Since they are part of a group, how their relationship affects and is affected by their friends is often a focus.
A typical theme would be the support system around them. Their friends would play a big role in this fanfiction. For example, Sheldon might struggle with the idea of there being a baby in his close - knit group but still end up being surprisingly helpful. And the theme of family could be explored, not just the family they are creating but also their extended families. Maybe Penny's family has some old - fashioned ideas about pregnancy and child - rearing that conflict with what she and Leonard want, leading to some interesting plot twists.
One common theme is the couple's relationship growth. Pregnancy often brings a new level of closeness and understanding between them. They might have deeper conversations about their future as a family.
Another is their career - related stories. For instance, Penny might be trying to break into acting in a more serious way and the guys help her in some unexpected ways. Howard could be working on a big project at NASA and the others are there for support. Raj, being an astrophysicist, might be involved in some international research and share his experiences with the group. And Leonard is constantly dealing with the pressures of his work at the university, and his friends are there to cheer him up or give him advice.
Their relationship would likely become more centered around the baby. They would have to make decisions together for the baby's well - being.
Their relationship could develop through shared hobbies. For instance, if Penny starts to show more interest in Leonard's scientific work, it can bring them closer. They can have deep conversations about his research, and Leonard can teach her new things.
Another theme is friendship or begrudging respect. Since they are from different 'sides' initially (Barry as a hero and Leonard as a villain or anti - hero), stories often explore how they come to see value in each other. For example, they might start off as enemies but end up as allies, and the journey of how that happens is a common theme. It can involve things like Leonard using his skills to help Barry in a tricky situation and Barry showing Leonard there is more to heroism than he thought.
The fanfiction could explore how Penny's pregnancy affects her acting career. She might have to turn down some roles because of her condition, which could lead to some self - doubt and worry. Leonard, being the supportive husband, tries to cheer her up by telling her how amazing she is and that she'll be back in action after the baby is born. And perhaps they discover some new things about each other during this time, like Penny's sudden craving for Leonard's special scientific - themed cookies he bakes on rare occasions.
A popular story could be about how they first met and the initial attraction. Leonard was smitten with Penny right from the start, and Penny gradually saw the good in Leonard. Their first date, which was filled with nervousness and some awkward moments, was a key part of their relationship's origin. Also, their story of living together brought new challenges and joys. They had to learn to share space, deal with each other's habits, and that was an important aspect of their relationship development.
One common theme is friendship. Since they are such different characters in the show, it's fascinating to see how fanfiction writers develop their friendship. For example, Penny might teach Sheldon about social norms while Sheldon might introduce Penny to some scientific concepts in a fun way.
One common theme could be the reactions of the other characters. How they support or react to Penny's pregnancy situation.
