In these fanfictions, Rey could develop a new sense of purpose. Instead of just focusing on being a Jedi and fighting the First Order, she now has to consider the future of her child. This could lead to her exploring different ways to bring peace to the galaxy. Kylo, on the other hand, may struggle with his identity. He has been a part of the dark side for so long, but the pregnancy could be a catalyst for him to try and find a middle ground, perhaps even trying to redeem himself in the eyes of Rey and their unborn child.
One interesting aspect could be how their relationship evolves in the context of this unexpected pregnancy. Maybe they start to communicate more deeply and understand each other on a new level. For example, Derek might become more protective of Stiles, and Stiles could discover a newfound strength within himself as he prepares to become a parent.
It can create a lot of drama. It might lead to Stiles feeling isolated and having to deal with the pregnancy on his own, which can be a major plot point. Maybe Stiles will then try to prove himself independent or try to find other support systems.
In these fanfictions, character development can also be seen in how Naruto and Sasuke handle the external pressures related to their marriage. Naruto, being the more positive one, could inspire Sasuke to face the world with a more optimistic attitude. And Sasuke's determination could rub off on Naruto, making him more focused. Their individual growth is intertwined with their relationship growth. For instance, they might start to train together more often, sharing their skills and knowledge, which not only improves their ninja abilities but also deepens their bond.
In these fanfictions, their character development is intertwined. Naruto's positive attitude can influence Sakura to be more optimistic. And Sakura's intelligence can help Naruto make better decisions. For instance, if they travel to a time when they are still genin, Sakura can guide Naruto in his training, and Naruto can inspire Sakura to be braver in battles, which is different from their original development in the main series.
Stiles would probably handle it with his usual sarcasm at first. He might make jokes about his situation to ease the tension. But as the pregnancy progresses, he would become more serious. He'd likely rely on his friends for support, asking for advice on things like dealing with morning sickness.
Stiles might become more guarded and distrustful. His experiences with an abusive mom could make him hesitant to open up to others. He may also develop a strong sense of self - reliance as he learns not to depend on her for emotional support.
He might use Stiles' knowledge of Scott. Stiles knows Scott better than almost anyone, so Derek can learn about Scott's likes, dislikes, and habits from Stiles. For instance, if Derek wants to give Scott a gift to win him over, he can ask Stiles what Scott would like.
Well, in some fanfictions, Stiles might try to hide the injury at first, not wanting Derek to feel guilty. He could use his own knowledge of first aid to patch himself up as best as he can.
Stiles usually reacts with a mix of fear and defiance. He's afraid because he's in a dangerous situation, but his strong - willed nature makes him defiant. For example, in many fanfictions, he'll shout at Peter, trying to show that he won't be easily broken.
