An interesting plot could be that the OC is a chef who starts working at the hotel's restaurant. Rafael is initially skeptical about the new hire but soon realizes the OC's talent. As they work together to improve the restaurant, they start to develop feelings for each other. The OC could also be involved in some of the community events related to the hotel, and through these, they get closer to Rafael and become a part of the complex web of relationships in the 'Jane the Virgin' universe.
One idea could be that Jane and Rafael face unexpected challenges during the pregnancy, like financial difficulties. Maybe Rafael's business hits a rough patch and they have to cut back on their lifestyle. Another could be that they find out they're having twins and start preparing for double the joy and double the chaos. They could also have an argument about the baby's name that turns into a big misunderstanding but they eventually resolve it.
To create a believable OC, start with a clear backstory. For example, if the OC is a journalist, explain how they got into the field, what their first big story was. Then, give them distinct personality traits. Maybe they're really sarcastic but also very empathetic. This will make their interactions with Rafael more interesting.
Another possibility is a crossover with 'Jane the Killer' (but in a non - horror way). They could meet and discuss how having the same name has affected their lives in different ways, and share their unique stories.
Well, a plot could involve Loki and Jane being accidentally transported to a parallel universe where their roles are reversed. Jane has to deal with the politics of Asgard while Loki tries to understand Earth's scientific concepts. Or, perhaps they are both caught in a time - loop where they keep repeating a day, and they have to figure out how to break it together, learning more about each other in the process.
Perhaps in the fanfiction, the dragon gets injured in a fight with a new, mysterious foe. Jane then has to journey far and wide to find a rare healing herb that only grows in a dangerous enchanted forest. Along the way, she meets various magical creatures who either help or hinder her mission.
Well, you could do a fanfiction where Jane has special powers. For example, she can communicate with animals. This would add a whole new dimension to her time at Thornfield. She could use her power to sense danger around the house. Or, perhaps a fanfiction where Rochester doesn't lose his sight and hand in the fire. How would their relationship develop differently? Also, a fanfiction set in an alternate universe where Thornfield is a magical place full of secrets and Jane has to use her wits to uncover them.
One plot idea could be that Jane and Gunther go on a quest together to find a rare herb that has the power to heal the dragon when it gets sick. They face various obstacles like a treacherous swamp and a mean - spirited forest spirit.
Some fanfictions focus on their daily married life. Like how they divide the household chores, or have date nights. In one fanfic, Jane surprises Rafael with a home - cooked dinner after a long day at work for him. It was a sweet moment that showed the love in their marriage.
Well, a plot could involve Naruto teaching the Volturi some of his ninja skills. Jane might be a quick learner and use these skills to gain more power within the Volturi ranks. Or perhaps Naruto falls in love with Jane, which causes a stir in both the Naruto universe and the Volturi world. Their relationship could be a catalyst for a new era of peace or chaos depending on how others react to it.
Perhaps Jane discovers she's pregnant while Tarzan is away on a long hunt. She then has to fend for herself for a while, relying on the skills Tarzan has taught her. When Tarzan returns, he's overjoyed but also realizes he needs to be more present. They could face challenges like finding proper food for Jane during her pregnancy in the jungle setting.
