I'm not sure specifically if there is a fanfiction with Susan and Caspian where there is a pregnancy. There are a vast number of fanfictions out there, and it would depend on the creativity and direction of different authors. Some fanfictions might focus on adventure and relationship building between the two characters without including such a plot element, while others might explore more complex storylines that could involve pregnancy.
In many Prince Caspian fanfictions that don't involve the inappropriate pregnancy theme, they often focus on the adventures they could have together. Maybe they go on a quest to find a lost magical artifact. Their relationship can be portrayed as a deep friendship or a budding romantic connection. They might face challenges like dealing with new magical creatures or solving mysteries within Narnia.
Well, Susan is often seen as a bit more worldly compared to Caspian in some fanfictions. Since she has been to Narnia before and has some knowledge of different cultures and magic there. Caspian, being from Narnia but in a different era, is in awe of her in a way. Their relationship can be complex. It could be a relationship where they both learn from each other. Susan can teach Caspian about the 'old ways' and Caspian can show Susan the new Narnia he is building. This kind of interaction makes for really engaging fanfiction.
One possible fanfiction could be set in a magical forest. Caspian and Susan meet by chance while she is exploring. They start with a simple conversation, sharing their love for nature. As time passes, their connection deepens, and they go on adventures together, protecting the forest and its creatures. Their relationship blossoms as they face challenges side by side.
One common theme is adventure. Since both characters are often associated with fantastical worlds, they embark on exciting quests together in many fanfictions. Another theme is love. Whether it's a budding romance or a deep, unspoken affection, it's frequently explored.
Perhaps a plotline where the pregnancy is unexpected and it throws Susan Caspian's life into chaos. She might have to make difficult decisions regarding her future, her relationships, and her own identity. There could also be a plotline where the father of the baby is in some sort of mystery or danger, adding more drama to the story.
A possible plot is that Susan discovers she is pregnant during a time of unrest in Narnia. Caspian is worried about how to protect her and the unborn child. They decide to go into hiding for a while in a secret part of Narnia. There, they live a simple life, and Caspian learns to be more self - sufficient, like fishing and hunting for food. As the pregnancy progresses, they form a deeper bond. Eventually, they return to the kingdom when things have calmed down, and they are welcomed with open arms as they await the birth of their child.
One possible fanfiction could start with Susan discovering she is pregnant. Caspian is overjoyed but also filled with a sense of responsibility. They start preparing a nursery in the castle, with Caspian bringing in the finest woods and fabrics. Susan spends her days knitting baby clothes, dreaming of their future child. Their friends in Narnia are excited too, and they all gather to offer their support and gifts. As the pregnancy progresses, they face some challenges, like when Susan has a difficult day of morning sickness, but Caspian is always by her side, bringing her soothing herbal teas.
A common theme is the cultural differences they might face. Since they come from different worlds in the original stories, fanfiction often explores how they bridge those gaps in their married life.
Susan was a noble lady, and Caspian was a brave king. At a grand ball in Narnia, Susan caught Caspian's eye. He asked her for a dance, and as they twirled around the ballroom, they felt a connection like no other. Caspian took Susan on rides through the beautiful Narnian countryside. They talked about their dreams and fears. With each passing day, their love blossomed. Susan found in Caspian a man she could trust and love with all her heart, and Caspian saw in Susan a true partner.
Another theme could be the integration of Susan's human world values and Caspian's Narnian ways when it comes to parenting. This can lead to interesting cultural clashes and reconciliations. And of course, the theme of love is always present, not just the love between Susan and Caspian but also their love for their baby and how it shapes their actions and decisions in the story.
