A really interesting plotline could be them having a child. The child would be a mix of human and Goblin King heritage. This would bring a whole new set of problems and joys. They would have to protect the child from those who might want to use its unique powers, and also teach it about both of their worlds.
Perhaps a plotline where they have to deal with the differences in their worlds. Sarah comes from the human world and Jareth from the magical realm. Their married life could be about finding a balance between the two, like how they decorate their home, half with human items and half with magical ones.
One possible plotline could be Sarah's initial resistance. She might try to find ways to escape the forced marriage, leading to a series of adventures within the Goblin Kingdom. Another could be Jareth slowly realizing his feelings for Sarah during the course of the forced marriage and trying to win her over in his own, rather complex way.
Well, aside from Jareth and Sarah, there could also be other characters from the original story that play important roles. For example, the goblins might be characters that are constantly around. They could be either helpful or cause trouble for the newly married couple. Also, Sarah's friends or family from the human world might be in the story. They could be trying to understand her new life with Jareth, or perhaps be worried about her being in the magical world. And who knows, there might be some new magical characters created just for this fanfiction to add more drama and storylines to their married life.
There might be a fanfiction where Sarah has to team up with Dark Jareth against a common enemy. They start to understand each other better during this adventure. For example, they face a powerful dark force that threatens both their worlds.
One interesting plot could be that Sarah, after being kidnapped, discovers a hidden side of Jareth's kingdom that he has kept secret from everyone. She finds out that there are other captives there who are being held against their will for reasons she has to uncover. As she tries to escape and free the others, she starts to see Jareth in a different light, not just as a captor but as a complex being with his own motives and past traumas.
In fanfiction, the idea that they come from two completely different realms, the human world and the Goblin Kingdom, adds to the allure. Their relationship can be seen as a bridge between these two worlds, and how they navigate the cultural and magical differences is fascinating. For example, in some stories, Sarah has to learn the ways of the Goblin Kingdom to be with Jareth, and Jareth has to understand human emotions better. This dynamic makes for a rich and engaging story.
Yes, there might be some. You can start by looking on fanfiction websites like Archive of Our Own. Just search for 'Jareth and Sarah forced married' in the search bar and you'll likely find several stories. However, the quality can vary a great deal.
Perhaps the pregnancy is a result of some magical mishap. Sarah then has to deal with not only the physical changes but also the strange magical implications. Jareth could be trying to find a way to reverse it at first but then grows to accept it as their new reality, which would create a lot of drama and character development.
One interesting plot idea could be that Sarah, years after her initial adventure in the Labyrinth, finds herself drawn back in a strange dream. In this dream, Jareth appears more vulnerable than she remembers. She discovers that there's a dark force threatening the Labyrinth and Jareth needs her help. They have to work together, and along the way, they start to understand each other on a deeper level, perhaps even developing feelings for one another.
In the fanfiction, the pregnancy could be a symbol of a new beginning for the relationship between Jareth and Sarah. It forces them to re - evaluate their feelings for each other. Sarah might become more empathetic towards Jareth's loneliness in his magical world, and Jareth could start to understand the importance of human emotions. They could embark on a journey to find a safe place for their baby to be born, facing various challenges along the way that test their love and commitment.
The relationship might become more intense. With the pregnancy, they have to rely on each other more. Jareth may show his softer side as he takes care of Sarah, and Sarah might start to see him in a new light, beyond the intimidating Goblin King.
