One idea could be that Emma discovers Rumpelstiltskin has a hidden side that is both alluring and dangerous. Their relationship could start as a power struggle but turn into an unexpected romance. For example, in a situation where they are forced to work together to solve a magical mystery in the Enchanted Forest.
Perhaps Emma gets trapped in a magical realm created by Rumpelstiltskin. At first, she's angry and tries to escape, but as she spends more time there, she starts to understand his motives and they develop a connection. It could involve Rumpelstiltskin showing her his past traumas through magical illusions, which makes her see him in a new light.
The Evil Queen could be a great antagonist. She might see the relationship between Emma and Rumpelstiltskin as a threat to her power. She could try to drive them apart by creating misunderstandings and false scenarios that make them doubt each other.
One idea could be a story where Belle discovers a hidden side of Rumpelstiltskin's past that changes her view of him. Maybe she finds out about a lost love he had before he became the Dark One, and this new knowledge makes her more empathetic towards him.
One idea could be to explore Rumpelstiltskin's backstory in more depth. Maybe he wasn't always so greedy and his transformation into the tricky character we know was due to some past trauma. For example, he could have been wronged by a powerful figure in his youth, which led him to seek power through his deals.
They could be brought together in a modern - day setting. Snow White has been transported to the modern world and Emma Lemon is the only one who believes her story. They then team up to find a way to get Snow White back to her own time. In the process, they face challenges like dealing with skeptics and also discover that there are hidden magical forces at work in the modern world that are somehow related to Snow White's past.
Here's an idea. Emma could be a mortal who accidentally stumbles upon the world of demigods. Percy is tasked with protecting her while also trying to keep the secret of the demigod world from getting out. As time passes, Emma shows an uncanny ability to understand the demigod world, almost as if she has some latent demigod blood in her. They develop a bond as they face various monsters and challenges sent by the gods who are not happy with a mortal being so involved. Their relationship could be a mix of friendship and something more as they go through these experiences together.
One idea could be the challenges they face as new parents. Maybe Will struggles to balance his teaching job with being a father while Emma is overly cautious about the baby's every move. Another could be a story where they discover an unexpected talent in their baby that somehow ties into the glee club. For example, the baby has an amazing ear for music.
Well, a plot could involve Emma trying to balance her school life with her pregnancy. She might face bullying or judgment from classmates, but also find support from unexpected places. Maybe she decides to join a support group for teen moms at Degrassi and forms new friendships there.
One idea could be that Emma, a modern - day girl, somehow gets transported to Neverland. She then has to learn to adapt to the strange and magical world. Peter Pan is initially suspicious of her but as they go on adventures together, like facing Captain Hook, they start to form a strong bond.
A plot could involve Wolverine and Emma Frost in a time - travel adventure. They go back in time to prevent a catastrophic event that would wipe out mutants in the future. During this journey, they face challenges that test their loyalty to each other and their mutant kind. Or perhaps a story where Wolverine's healing factor is somehow linked to Emma Frost's diamond form, and they have to figure out how to control this new connection for the greater good. Also, a plot where they are on opposite sides at first in a mutant civil war but then realize they have more in common than they thought and switch sides together.
One plot idea could be that Emma and Charlotte discover a new Miraculous. They have to figure out how to use it while keeping it a secret from Hawk Moth. Maybe they face challenges like a new villain who is specifically targeting them because they are so close to Ladybug and Chat Noir.
