The relationship between them all would be in chaos. Robin, being a loyal person, would probably cut off all ties with Regina. Regina would then have to face the loss of Robin and deal with her new relationship with Emma. Emma, on the other hand, would have to deal with the fact that she's now in a relationship that started through cheating. This could lead to a lot of drama and tension between the three characters in the fanfiction.
In some fanfictions, Regina might leave Emma for Robin because of a deeper emotional connection she feels she has with Robin. Maybe she sees in Robin something that she feels is lacking in her relationship with Emma, like a more traditional form of love or a different kind of understanding.
One consequence could be that Emma feels betrayed and heartbroken. This might lead her to become more closed off in future relationships. For Regina, she might face some internal conflict as she adjusts to her new relationship with Robin, constantly comparing it to what she had with Emma.
One possible plotline could be that Regina starts to develop feelings for Emma while still in a relationship with Robin. Maybe during some magical adventures together, she sees a different side of Emma that she's attracted to. This could lead to internal conflict within Regina as she tries to deal with her newfound emotions while not wanting to hurt Robin.
Some fanfictions depict them going on quests that test their limits. For instance, they could be on a journey to rescue a kidnapped friend. Along the way, they face many obstacles, but their determination and growing bond help them overcome each difficulty. They learn more about each other's pasts and how those experiences have shaped who they are today.
One common theme is redemption. Regina has a complex past, and in many fanfictions, Emma helps her on her path of redemption. For example, in some stories, Emma's belief in Regina's ability to change is a central plot point.
In fanfiction, the concept of Emma, Regina, and a magic baby often brings a unique blend of magic and character dynamics. Writers might explore how the magic in the story world affects the baby's development or how the relationship between Emma and Regina evolves because of the baby. It could be a source of great conflict or a means to bring the two characters closer together.
Friendship is another theme. They start as adversaries in the original story, so fanfictions often explore how they can become friends. This can involve them sharing secrets, protecting each other from threats in Storybrooke, and learning to trust one another.
