Well, the characters can be developed through their dialogues. In this fanfiction, the sister could have conversations with other 'Twilight' fans or characters she imagines from the series. Through these dialogues, her personality traits like her passion, her naivete or her wisdom can be shown. And for the non - human characters like vampires or werewolves, their backstories can be gradually revealed, like how they became what they are and how that shapes their actions towards the sister.
One possible plot could be a sister who is deeply involved in the 'Twilight' world. Maybe she has a relationship with a vampire or werewolf. But then she faces a life - threatening situation that makes her say 'goodbye life'. For example, she might be hunted by vampire hunters because of her relationship with a vampire and in the end, she sacrifices herself to save her vampire love.
Well, character development in 'Accidentally in Twilight Fanfiction' can be really interesting. Take the case of a character who accidentally witnesses a vampire's act of mercy. This could make them question their pre - conceived notions about vampires, leading to a change in their attitude towards the whole vampire race. Also, when characters accidentally get caught up in a prophecy or a long - standing feud between supernatural entities, they are forced to adapt and grow. They might have to make difficult choices, like whether to protect their own kind or side with the accidental friends they've made from other groups, and these choices can define who they become.
They could be developed by giving them new powers or abilities. Suppose Laurent discovers he has the ability to manipulate the weather in a small way. This new power could change his self - perception and how others, including Irina, see him. Irina could develop the ability to communicate with animals. This would not only make her more interesting but also create new storylines where she uses this ability to help Laurent or in their adventures together.
Another way is to put them in situations that challenge their loyalty to the Volturi. In the Twilight world, the Volturi are very powerful and feared. But if Jane and Demetri are faced with a situation where they have to choose between doing what the Volturi want and what they believe is right, it would show different aspects of their characters. They could also interact more with other characters outside of the Volturi, which would force them to adapt and grow.
To develop Demetri further, you could explore his past. Maybe he had a human life before being turned that he barely remembers, but certain events in the fanfiction could trigger those memories, adding depth to his character. For Heidi, you could show more of her vulnerability. She's often seen as this seductive figure, but what if she has insecurities about her role in the Volturi?
The relationship can start with the child player being curious about the neighbor. As the story progresses, they could have small interactions that slowly build trust or suspicion, depending on how the writer wants to develop it. For example, if the neighbor saves the child player from a small accident in the yard, it could be the start of a more positive relationship.
In the fanfiction, their characters could develop in relation to each other. For example, Twilight Sparkle's studious nature could rub off on Flash Sentry, making him more interested in learning. On the other hand, Flash Sentry's adventurous spirit could encourage Twilight to take more risks and step out of her comfort zone. This mutual influence could lead to a more well - rounded development of both characters as the story progresses.
The characters can be developed by giving the twin sister her own unique personality traits. For example, if Naruto is known for his determination, the sister could be known for her intelligence. Their relationship can also be developed by showing how they interact in different situations, like in battles or during family moments.
Alice's brother, Jasper, is also often overlooked. His backstory as a Confederate soldier turned vampire is full of potential for fanfiction. Writers could delve into his struggle with his past and how it affects his relationships in the present. Maybe a fanfic could show him trying to make amends for his actions during the Civil War in some way within the Twilight universe.
In terms of the Cullens' family relationships, in a split second, Carlisle could be put in a situation where he has to choose between his family and his principles. For example, if a new vampire law is created that goes against his beliefs, and his family is in danger because of it. This would force the family to re - evaluate their relationships with him and with each other as they deal with this new situation.
