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.
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.
The contrast between their characters. Susan is often seen as more reserved and proper, while Caspian is bold and adventurous. When they kiss, it's a moment that breaks the expected boundaries, which is really exciting.
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 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.
A plot could involve Caspian being cursed and Susan being the only one who can break it. She has to go on a quest to find a magical object. Caspian, in his cursed state, can't directly help but his spirit encourages her. Along the way, Susan discovers her own hidden powers and in the end, she breaks the curse and they confess their love for each other.
There is a fanfiction where Susan is a healer and Caspian is injured in battle. Susan takes care of him and during his recovery, they start to realize their feelings for each other. It's a slow - burn story that really delves into their personalities and how they complement each other.
