I'm not sure if there is a specific fanfiction exactly with those elements. Fanfiction can cover a wide range of scenarios, but this seems rather inappropriate and not in line with the general respectful portrayal of the Titanic story. The Titanic story is often remembered for its tragic and romantic aspects in a more refined way.
No, it is not appropriate. Such content often involves disrespect to the original work and may also cross ethical boundaries. The 'Titanic' is a classic movie with a certain degree of solemnity and elegance, and creating this kind of fanfiction violates the respect that should be given to the story and its characters.
One possible storyline could be that Rose discovers she's pregnant after she and Jack's brief but passionate encounter on the ship. This could add a whole new layer of drama. Maybe she tries to keep it a secret at first, fearing the reaction of her mother and Cal. As the Titanic starts to face its doom, she's not only worried about her own survival but also that of her unborn child.
In this fanfiction, Rose being pregnant might lead to a situation where she has to fight for her rights to keep the child. Her family, who may not approve of her relationship with Jack, could try to take the baby away. So she has to prove that she can be a good mother on her own. She might also document her pregnancy journey in a diary, writing about her memories of Jack and how she hopes the baby will grow up with the same love for life that Jack had.
A fanfic could explore how Rose's pregnancy changes her relationship with Jack. Jack would be overjoyed but also concerned about the responsibility. They could plan for their future and the baby's future, even in the midst of the luxury and class differences on the Titanic. It could also show how Rose's pregnancy gives her more strength to face the challenges on the ship, like standing up to Cal and his controlling ways.
Perhaps in the fanfiction, Rose is pregnant and the Titanic doesn't sink. When they reach their destination, they have to figure out how to build a life together with a baby on the way. They face challenges like finding a place to live and Jack finding a stable job. But their love for each other and the anticipation of the new life keep them going.
Well, the plot could be that Rose is pregnant with Jack's child. They try to find a way to start a new life together in America. However, they face many obstacles on the Titanic. For example, Cal might find out about the pregnancy and try to take the baby away from Rose once they reach land. This would create a lot of tension and conflict.
Rose might stand up to Cal bravely. She could tell him that she will not let him control her life anymore, especially now that she has a child to think about. She would be defiant and make it clear that she wants nothing to do with him.
Maybe in the fanfiction, Jack actually survives. When Rose finds out she's pregnant, they are both overjoyed. However, they face the problem of how to start a new life. They might decide to leave for a new place, away from the prying eyes of Rose's family and the upper - class society. They build a small house near the sea and raise their family there, with Jack working hard to provide for his family and Rose taking care of the home and the new - born baby.
In Titanic fanfiction, Jack and Rose's relationship can be explored in various ways. One way is through their shared interests. For instance, Jack's love for art could be the bond that draws Rose closer to him. They might spend hours talking about different art forms and artists, which deepens their emotional connection.
