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 way their relationship can develop is through dealing with external problems together. For example, if there are issues with their apartment or with their friends. By facing these problems as a team, they learn more about each other's strengths and weaknesses and their relationship deepens.
It could also develop as they start a family. In the fanfiction, they might decide to have a baby. This new chapter in their lives would bring new challenges and joys. They would need to support each other more, and it would strengthen their bond as a couple.
Their relationship would likely become more centered around the baby. They would have to make decisions together for the baby's well - being.
For Leonard, writers could explore his relationships with his colleagues at work. Maybe there's a competition at the university and he has to work extra hard. How does Penny fit into this situation? Does she encourage him or is she a bit jealous of the time he spends at work? For Penny, show her growth as an individual. She could take some acting classes and Leonard could be her practice partner. This can enhance both of their characters in the fanfiction.
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.
Maybe in the fanfiction, Penny and Leonard decide to have a big party after getting married to celebrate with all their friends and family. There could be a lot of humorous moments, like Sheldon trying to take over the party planning with his own unique rules.
We can focus on their friendship. Their friendship was the foundation of their relationship. We can write about the times they just hung out as friends, like when they watched movies together or had game nights with their friends. This shows a positive side of their relationship without any inappropriate elements.
Well, at first, it might be a bit of a struggle. There could be arguments over who does what more. But as they figure things out, they would realize how much they need each other. The baby would be a symbol of their love and commitment, and they would work hard to make their relationship work for the sake of their child. They would also find new things to love about each other as they see how the other interacts with the baby.
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.
Fanfiction in this regard can show the deepening of their bond. It can explore the more private and vulnerable sides of their relationship that might not be fully shown in the show. For example, it can show how they communicate during these intimate moments.
Howard and Bernadette would be great godparents. They are good friends with Penny and Leonard, and they already have experience with raising a child. Howard could teach the baby some engineering tricks, while Bernadette could offer motherly advice.
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.
