Jimmy in 'Jimmy's Confessions' could be a character with a complex personality. He might be a middle - aged man who has led an eventful life. Maybe he's a writer who is using his confessions as a way to tell his own story, or he could be someone who has just reached a point in his life where he feels the need to unburden himself of all his secrets.
One possible fanfiction could be that Jimmy has a secret mission, and Heloise accidentally gets involved. They start off not getting along well because of their different personalities. But as they face difficulties during the mission, they gradually learn to understand and rely on each other, and in the end, they become great friends.
One common theme could be loyalty. Given the nature of Daryl Dixon's character in the original show, loyalty to friends or comrades like Gene Dixon and within the context of Trinity might be a big part of the fan fictions.
A great fanfiction idea could be that Jimmy discovers a hidden talent that Heloise has. He is amazed by it and tries to help her develop it further. Along the way, they share many laughs and some minor setbacks, but ultimately, Heloise's talent becomes something that benefits their whole community.
Daryl Dixon isn't gay in the comics. The storylines mainly revolve around his adventures and struggles in a post-apocalyptic world, not his sexual orientation.
It depends on their popularity and the creativity of fans. If people are really into their characters and potential relationship, fanfiction could definitely exist.
