One idea could be a story where they team up against a new, more powerful enemy that threatens their world. Maybe they have to put aside their differences and combine their unique abilities to defeat it.
One common theme is power dynamics. Since both Alex Mercer and Elizabeth Greene have unique and powerful abilities, many fanfictions explore how their powers interact. For example, in some stories, they might compete to see who is more powerful.
To create a believable relationship, you need to focus on their shared experiences. They both have these extraordinary powers and are somewhat outcasts in the normal world. By highlighting how they understand each other's isolation, you can start to build a connection.
I'm not sure of specific 'alex mercer x elizabeth greene fanfiction' titles off the top of my head. But you could also try Archive of Our Own. It has a large collection of fanfictions, and you can use the search function to specifically look for stories about these two characters. Some fanfictions might focus on their powers and how they interact with each other in a world full of chaos and danger.
Another theme could be sacrifice. For example, Hershel might be written as being willing to sacrifice a great deal for Beth's happiness or safety, and this sacrifice is a testament to his love for her. Also, the theme of forgiveness might come up, if there are any misunderstandings or past issues between them in the fanfiction.
Nicci Greene could be an author, but if she is mainly known for writing erotic stories, I can't provide more details as it involves inappropriate content. There might be other Nicci Greenes in different fields.
One place to find such fanfiction could be Archive of Our Own (AO3). Just search for 'Beth Greene and Hershel Greene' in the relationship tags, and you'll likely come across some great stories.
The story also has themes of class. Mr. Thomas, known as Old Misery, is from an older, perhaps more genteel class. The boys, coming from the working - class rubble of the post - war world, see his house as something to be torn down. This shows the tension between the old and new, the haves and have - nots. Greene's writing style is sparse yet evocative, making the reader feel the desolation of the setting and the motives of the characters.
The story 'The Destructors' is a powerful exploration of post - war youth and their sense of alienation. The boys in the story, led by T., are from a broken world. They see the old beautiful house as a symbol of the past they want to destroy. It shows how the war has affected not only the physical world but also the moral and psychological state of the young generation.
I'm not sure. It's possible that it's a mix of truth and imagination. We'd need more background information and verification to know for certain if it's truly real.
