One possible plot could be that August has some important information to share with Emma about her past or the impending danger in Storybrooke. Maybe he stays with her to protect her from the villains who are after her powers. For example, he could know about a new curse that is about to be cast and needs to keep her safe until they can figure out a way to stop it.
A great plot idea is that August, who has some knowledge of the future through his writing, tries to prevent a dark prophecy that involves Emma. They could also start to develop feelings for each other while investigating a series of strange disappearances in town. Maybe August is actually from a different realm and Emma has to help him get back while uncovering the truth about his origin and its connection to her own story.
Their relationship could be developed realistically through shared experiences. For example, if they both work on solving a mystery in town, they'll start to trust and rely on each other more. They might also have small, everyday interactions like having coffee together and gradually getting to know each other's quirks and pasts.
A friendship could develop. They could start off as just acquaintances, but as August stays with Emma, they might find common interests. For instance, they could both be interested in finding a way to break certain curses in Storybrooke. This shared goal could lead to a strong bond of friendship as they work together towards it.
Well, perhaps the fanfiction could focus on Hook's backstory related to the birth. Maybe he had some past experiences that make him extra cautious during Emma's pregnancy. For example, he might have witnessed a difficult birth in his pirate days that scarred him. So when it's Emma's turn, he's constantly on edge. The plot could then revolve around him coming to terms with his fears and being there for Emma as she gives birth.
The theme of identity in relation to the fairytale world could be prominent. In 'Once Upon a Time', characters often have dual identities. August's gay identity could be another aspect of this, and the fanfic could explore how this new identity fits in with his fairytale - related identity, like being Pinocchio. It could also deal with themes of isolation or belonging, as he navigates a world that may or may not be fully inclusive of his identity.
It could also be a story of a short - lived but intense relationship. They met during a special event or a trip. They had a whirlwind romance, full of passion and excitement. But then, due to some unforeseen circumstances like one of them having to move away for a job or study, they had to part ways, leaving August with bittersweet memories.
One heartwarming scene could be when Emma first tells her closest friends about her pregnancy. Their excited reactions and immediate offers of support would be really touching. For example, Snow White might start knitting baby clothes right away, with a big smile on her face.
One plot idea could be that Emma has a scar from a battle with a dark magic creature. The scar gives her unique powers that she has to learn to control. Another could be that the scar is a symbol of a past life she's starting to remember, leading to adventures in forgotten lands. Maybe the scar is part of a curse, and she has to find a way to break it before it's too late.
One possible plot could be that Emma discovers a long - lost family secret. Maybe her parents were part of a magical society and they hid this from her to protect her. As she uncovers the truth, she has to learn to control newfound powers and face an old enemy of her family.
Another common theme is relationship - centered. For example, exploring how their relationship develops further, like dealing with jealousy when new characters come into their lives. There might be a story where David has to prove his loyalty to Emma in a difficult situation.
