Arya may become more confident in her abilities with Jaqen's guidance. She could grow from a somewhat reckless girl into a more calculated and strategic assassin. For example, she might learn to better plan her attacks instead of acting on impulse all the time.
Perhaps in the fanfiction, Arya and Jaqen form an unexpected bond due to the pregnancy. Jaqen, who is usually a mysterious and somewhat aloof character, could show a more caring and protective side. They might have to find a safe place to stay, away from the chaos of their normal lives, and figure out how to raise a child in a world full of danger and intrigue.
At first, it could be a teacher - student relationship, with Jaqen teaching Arya more advanced skills of the Faceless Men. As time goes on, they might become comrades, relying on each other in dangerous situations.
For Arya, focus on her growth from a vengeful girl to a more complex character. Show her learning from Jaqen, not just in terms of skills but also in understanding different ways of life. Let her struggle with her identity as she is influenced by Jaqen.
Another plot could be centered around Jaqen teaching Arya some of his unique skills. Arya is already a skilled assassin, but Jaqen has his own brand of magic - like his ability to change his face. He could pass on some of this knowledge to Arya, and they could use it to infiltrate enemy strongholds and carry out their plans.
One common theme is the growth of Arya. With Jaqen in the story, Arya often has to learn new things, whether it's about combat or about the world around her, so her growth as a character is a big part.
A jaqen h'ghar x oc fanfiction offers a lot of creative opportunities. For example, the author could play with the idea of Jaqen's identity and how the OC reacts to it. The OC could be a key factor in Jaqen's character development. It could also be a story about redemption or self - discovery for both characters. There could be many plot twists and turns as they interact in different settings, whether it's in a bustling city or a desolate place.
Jaqen H'ghar was a Faceless Man. He was originally from the House of Black and White in Braavos. He was sent on various missions, and his story intertwined with Arya Stark's. He taught Arya many skills related to the Faceless Men, like changing faces and becoming no one.
To develop the story further, you can introduce conflicts related to the pregnancy. For instance, Arya's physical condition might limit her ability to fight or travel as she used to. This can create tension as she tries to overcome these limitations while still protecting herself and her unborn child.
One common theme is his mysterious identity. Writers often explore more about who he really is and his backstory. Another theme could be his relationship with other characters, like Arya Stark. There are also fanfictions that focus on his skills as an assassin and how he uses them in different scenarios.
