A possible plot twist is that the OC discovers that the pregnancy is not a natural occurrence but the result of some dark magic manipulation by an unknown enemy. This would make Regina and the OC go on a quest to find out who is behind it and how to reverse it if necessary. Meanwhile, they have to deal with the emotional turmoil of not knowing if the baby will be okay and whether they can trust their own feelings for each other.
Well, a plot twist might be that Regina's pregnancy is a false one, created by an illusion spell. This could be part of a larger scheme to make her look vulnerable and draw out her enemies. Or perhaps the baby she's carrying has some sort of special power that she has to protect it from other magical beings who want to use that power for their own gain. Also, it could turn out that the pregnancy is a result of time - travel shenanigans, where she got pregnant in a different time period and now has to deal with the consequences in her current time.
The relationship could become stronger. Regina, who has had a difficult past, might find new hope and softness in the idea of having a family with the OC. They could start to rely on each other more, sharing fears and hopes about the future. For example, Regina could open up more about her own past traumas related to family, and the OC could comfort her, creating a deeper bond.
Maybe Emma is actually from an alternate timeline where Regina was the one who sent her to our world for a greater purpose. As the story unfolds, this revelation makes Regina question her own motives and actions towards Emma throughout their time together.
One possible plot could be that the other characters in Storybrooke have to deal with the power vacuum left by Regina's death. Maybe her son Henry would struggle with his identity more as he no longer has his mother as an anchor. The Evil Queen's spells could start to go haywire without her there to control them, causing chaos in the town.
Well, a plot could involve time - travel. Henry somehow gets sent back in time to when Regina was first starting to embrace her dark side. He tries to change her path by showing her the future and how she could have a loving relationship with him. Another interesting plot might be that there's a curse on Henry that makes him forget Regina, and Regina has to go through a series of trials to break the curse and make him remember their relationship. Also, they could be on a quest to find a magical artifact that can restore all the good memories of the people in Storybrooke that Regina once took away, and this journey brings them closer together.
One idea could be that Regina, trying to redeem herself, takes Roland under her wing to teach him magic in a secret way. This could lead to a series of adventures as they have to hide their lessons from the rest of the town. Another plot could involve Roland getting lost in a magical realm and Regina being the only one who can sense his presence and rescue him, leading to a journey of self - discovery for both of them. And perhaps they could team up to stop an evil force that is threatening Storybrooke, with Roland's innocence and Regina's power being a perfect combination.
One possible plot could be that Regina and Sydney start off as reluctant allies. Maybe they are both trying to achieve something in the town of Storybrooke. For example, they might be looking for a magical artifact that could change the balance of power. Along the way, they discover that they have more in common than they thought. Sydney might be able to see past Regina's tough exterior and understand her motives, which are often a mix of self - preservation and a longing for something she lost in the past. As they search for the artifact, they face various obstacles, like other characters who also want the item for their own purposes. This could lead to some tense moments and action - packed scenes as Regina and Sydney have to use their wits and magic (if applicable) to outmaneuver their opponents. In the end, their relationship could develop into a true friendship, or perhaps something more, depending on the direction the fanfiction takes.
One idea could be that Regina and Dr Facilier form an unlikely alliance to take down a common enemy in Storybrooke. Maybe a new dark force has emerged that threatens both of their interests, so they have to put aside their differences.
Snow White might be initially suspicious, given their past history. But she could also show a more empathetic side and try to help Regina. Hook might be amused and make some snarky comments at first, but then offer his protection. Rumpelstiltskin could see it as an opportunity to manipulate Regina further, perhaps by offering her magic to ensure a safe pregnancy in exchange for favors.
A possible plot twist in a Regina Gets Pregnant Fanfiction could be that the pregnancy progresses at an extremely rapid rate. Instead of the normal nine months, it might be just a few weeks. This would force Regina to quickly adapt to the idea of being a mother and also deal with the physical and emotional changes in a very short time. Additionally, what if the baby is a key to unlocking a long - forgotten magic in the realm? This would make Regina a target for those who want to use the baby's power for their own gain. Or, it could be that Regina's pregnancy is a sign of a new era in the magical world, and she has to figure out how to lead the way into this new future while carrying the baby.
