One great 'TVD Caroline pregnant' fanfiction is 'Caroline's New Chapter'. It beautifully explores Caroline's journey through pregnancy while dealing with the supernatural world around her. The author does a wonderful job of portraying her strength and the support she gets from her friends.
There are many interesting fanfictions on this topic. Some might focus on how they deal with the pregnancy in the dangerous world of vampires and werewolves. For example, they could be facing threats from other supernatural beings who see their unborn child as a threat or a powerful asset.
The theme of sacrifice is often present. She may have to sacrifice her own desires or safety for the sake of her unborn child. In some fanfictions, she might even have to make difficult choices between her love life and the well - being of her baby, all while dealing with the vampires, werewolves, and witches that populate Mystic Falls.
Another theme is protection. Given the dangerous nature of their world, protecting the unborn child from various threats is often a central plot point. Enemies might try to harm the baby because of its potential power or to get revenge on Caroline and Klaus.
Caroline in the 'caroline found story' could be anyone really. She could be a scientist who found a new species or a new scientific principle. Maybe she's a writer who found inspiration for her next great novel. Or she could be a mother who found a way to better connect with her children. Without more details about the story, we can only speculate about who she might be, but she's clearly the central figure in this story about discovery.
I don't have enough information to determine who Caroline is in this story. She could be an ordinary person with an extraordinary secret, or a fictional character created for a specific narrative.
Since we don't have much information about the 'captured caroline' story, it's hard to say exactly who Caroline is. She could be the protagonist, a victim, or a key figure in some sort of adventure or mystery.
Caroline as a human in fanfiction with Klaus can create a really interesting dynamic. It allows for exploration of how a human might interact with a powerful vampire like Klaus. For example, she could be a source of light in his dark world, constantly challenging his views.
Without more information, it's hard to say who Caroline and Nicolas are exactly. They could be ordinary people with an interesting story, or they could be characters in a fictional narrative.
I really like 'Klaus and the Unlikely Companion'. In this fanfiction, the OC is a witch who crosses paths with Klaus. What makes it stand out is the way it portrays Klaus's vulnerability around the OC. It shows a different side of him that we don't often see in the show. The plot twists are also quite engaging.
