Many fanfics explore the theme of family as well. Emma has her own family ties in Storybrooke, and Hook has his own past family issues. How they fit into each other's family dynamics or create a new family unit of their own is a theme that adds depth to the stories. In some fanfics, they might be trying to protect their new - found family from a common enemy while also nurturing their relationship.
Adventure is also a big theme. They are often on some sort of quest or journey together. For example, they might be searching for a magical artifact while also dealing with their feelings for each other. And there's also the theme of trust. Since they come from different sides, learning to trust each other is a crucial part of many fanfics.
One common theme is redemption. Captain Hook often has a past full of misdeeds, and in these fanfics, his relationship with Emma Swan can be a part of his journey towards redemption. For example, in many stories, he tries to change for her.
In another scenario, both Captain Hook and Emma Swan are held for ransom by a new and powerful villain in their world. They have to work together, using their combined skills and the power of their relationship, to escape from captivity. This could involve Hook using his pirate wiles and Emma using her magic. They might also find unexpected allies along the way who help them in their quest to avoid paying the ransom and defeat the villain.
Adventure is also a big theme. They might go on quests together, explore new lands or face magical creatures. For example, they could be on a mission to find a lost magical artifact in Neverland. And there's the theme of trust - how they learn to trust each other over time, especially since Hook has a reputation for being untrustworthy at first.
One great fanfic is 'The Pirate's Heart'. It delves into a romantic relationship between Captain Hook and Emma Swan in a very engaging way. The story has a lot of adventure elements combined with their growing feelings for each other.
Another theme is the idea of redemption. Captain Hook is often portrayed as a villain in the original Peter Pan story. But in fanfiction with Bella Swan, he sometimes gets a chance at redemption through his interactions with her. Bella's kind heart might make him question his own motives and actions.
I also like 'Swan and the Pirate'. It starts with an encounter between them that sets the stage for a deeper connection. The story weaves in elements from the original show but adds its own unique twists. It has some beautifully written scenes that make you root for their relationship to work out.
There are quite a few out there. In some fanfictions, like 'A New Beginning for the Hook - Swan Family', it delves into how their relationship evolves with the addition of a baby. It might show Hook being overly protective and Emma being the more practical one when it comes to raising their child. The story could also involve their friends from Storybrooke helping them out in different situations.
One common theme is the exploration of her relationships. Her relationship with the baby's father, her friends, and her family often take center stage. For example, how they support her or how she navigates any relationship issues during pregnancy.
You can try fanfiction websites like Archive of Our Own (AO3). It has a large collection of fanfictions, and you're likely to find many about Captain Hook and Emma Swan having a baby there.
Perhaps they are in the middle of a new adventure when Emma realizes she's pregnant. This could add a whole new layer of tension as they not only have to deal with the external threats but also ensure the safety of the baby. They could seek help from their friends in Storybrooke, who have mixed reactions to the news.
