It depends on their popularity and the creativity of fans. If people are really into their characters and potential relationship, fanfiction could definitely exist.
Another common theme is growth. Both Maggie and Jackson often grow as individuals within the fanfiction. They might learn from their mistakes, overcome personal fears, and this growth is intertwined with their relationship. In some stories, Maggie might be shy at first but becomes more confident because of Jackson's influence.
Maggie Ireland from 'Rejected and Forsaken by Maggie Ireland' is the central character in terms of the actions described in the title. Without reading the story, we can't say much about her personality or character traits. She could be a mean - spirited person if the rejection and forsaking are unjust, or she could have her own reasons which the story might explore. Maybe she is a character who is going through some sort of personal struggle that leads her to these actions.
The popularity of Rick and Negan fanfiction lies in their complex relationship in the original series. They are two strong - willed leaders with different ideologies, which makes for a lot of interesting story - telling possibilities in fan - created works.
Negan might protect Carl out of a sense of respect. Carl has shown himself to be a strong and determined character, and Negan could admire those qualities.
There could be a really interesting fanfiction where the magical worlds of Charmed and Harry Potter collide with Harry and Maggie. Maybe they team up to fight a new kind of dark magic that threatens both their realms. They could each bring their unique magical abilities to the table. Harry with his wizardry from Hogwarts and Maggie with her powers as a Charmed one.
