In the fanfiction, perhaps Emma's pregnancy is a magical one. Maybe it was the result of some long - lost magic that got reawakened. Hook would be both excited and a bit scared. They could go on a journey to find a way to ensure the baby's safety in a world full of magic and curses. And Emma might struggle with her usual role as a savior while being pregnant, but Hook would be there to support her every step of the way.
Maybe Neal has some doubts about being a father because of his own troubled past. He could be worried that he'll repeat the mistakes of his father. Emma, on the other hand, is determined to have a happy family. This could lead to some emotional turmoil between them as they work through their issues while also preparing for the baby.
Well, another option could be to check out some Once Upon a Time - related forums. There are often fans who share their favorite fanfictions in those forums. Some of them might be about Emma and Neal being pregnant. You could ask in the forum if anyone knows of any good ones. For example, Reddit has some dedicated Once Upon a Time communities where you can start your search.
Well, on Archive of Our Own (AO3), there are some great fanfics on this topic. A popular one was about Emma's pregnancy in relation to the prophecy in the show. It delved into how the prophecy might be affected by the new life she was bringing into the world. It also had some really sweet moments between Emma and her family as they prepared for the new arrival.
A plot idea could be that Emma has prophetic dreams about the baby's future during her pregnancy. These dreams might show the baby having a great and important role in the magical world. Hook then becomes determined to make sure the baby can fulfill this role safely. Another idea is that a dark force tries to possess the unborn baby, and Hook and Emma have to find a way to prevent it, maybe by seeking help from Regina who has experience with dark magic.
One great Hook Emma fanfiction is 'A Pirate's Heart'. It beautifully captures the chemistry between them. The story takes them on an adventure where they have to face many challenges together, which deepens their relationship.
Hook would probably become even more protective. He's always been in love with Emma, but now with a baby on the way, he'd be constantly by her side. Emma, on the other hand, might struggle a bit with feeling less independent.
A plot could involve Emma having difficulties with her pregnancy due to her being the Savior and all the magic in her. Hook is overprotective and tries to find ways to ease her pain. Meanwhile, they learn that there are prophecies about their child that lead them on a journey to different realms to protect the baby's future.
A common theme is the exploration of Henry's powers. In the show, Henry has a special connection to the storybook world. Fanfictions often expand on this, with Emma being involved in helping him understand or control his powers. Also, the theme of redemption can be seen. For example, if a character has made mistakes in the show, fanfictions might show Emma and Henry being part of their redemption arc.
Another common one is relationship - centric storylines. Writers often explore how Emma and Hook's relationship develops further, like dealing with misunderstandings or facing challenges together that strengthen their bond. It could be something as simple as a family member not approving of their relationship at first and how they overcome it.
