In the fanfiction world, it might be part of a bigger plot against Lucy. There could be a character who is jealous of Lucy's relationship with other characters. So, they decide to frame her for hurting Lisanna as a way to get her in trouble and drive a wedge between her and her friends.
Lucy could face isolation. People in the fanfiction world might avoid her, and she could be left all alone. This could also lead to her losing confidence in herself as she is constantly being blamed for something she didn't do.
The plot could involve jealousy. Lucy might become jealous of Lisanna as she takes over her position in the guild. This could drive Lucy to train harder and become more independent. Maybe she'll find a new group of friends or allies who see her value outside of the guild.
Lisanna might face a lot of backlash from the guild. Her friends could be disappointed in her and might not trust her as much. She could lose her standing in the guild and have to work hard to regain people's respect.
Well, first of all, Lucy can try to have an open and honest conversation with Lisanna. By expressing her feelings and asking Lisanna why she is acting this way, she might be able to resolve the conflict. If that doesn't work, she can choose to rise above it. She can pour her energy into her magic training, become stronger, and show that she is not going to be brought down by Lisanna's actions. She can also look for new friendships outside of the group that may give her more positive energy and support. Another option is for Lucy to take a break from the situation. She can go on a solo adventure, clear her head, and come back with a new perspective on how to deal with Lisanna.
Well, perhaps Natsu is framed for stealing a powerful magical artifact. Someone could plant false evidence at the scene. Then he has to prove his innocence while also dealing with the distrust of his friends.
In a fanfiction of Lucy being replaced by Lisanna, it might explore the emotional turmoil of Lucy. She could be heartbroken seeing how easily she was seemingly replaced. Meanwhile, Lisanna might not be fully aware of the situation or might be caught up in the sudden popularity. This could create a rift not only between Lucy and Lisanna but also within the guild as a whole. Some members might side with Lucy, feeling that she was unjustly pushed aside, while others might be excited about Lisanna's presence and not understand Lucy's pain.
In this kind of fanfiction, they might face various challenges. Maybe they'll have to find their way back on their own. They could encounter dangerous magical creatures and have to rely on their own skills and the bond between them to survive.
Well, it could completely change the dynamic of their relationship. Firstly, they would have to deal with the responsibilities of impending parenthood. Natsu, being his impulsive self, might have to become more responsible. Lucy, on the other hand, would probably be more cautious about her actions as she has a life growing inside her. This event could also change their relationships with their friends in the guild. Their friends would likely rally around them, but there could also be some who might be shocked or even a bit envious. It could also lead to new story arcs, like how they prepare for the baby, finding a safe place to raise it, and what kind of parents they would be.
Well, it could start with Natsu and Lucy realizing what has happened. Natsu, being his impulsive self, might have some wild ideas about how to handle it. But as time goes on, he would start to understand the seriousness. Lucy would likely be the more practical one, thinking about things like preparing for the baby's arrival. Their relationship could become strained as they deal with the unexpected situation, but also grow stronger as they face it together.
To portray their friendship better, they could be shown sharing secrets. Maybe there's a secret place in the guild that only they know about, and they go there to share things like their first crushes or embarrassing moments from their childhood. Also, having them give each other meaningful gifts, like Lucy giving Lisanna a special keychain she made herself, and Lisanna giving Lucy a handmade scarf, would also strengthen the portrayal of their friendship.
