One challenge could be her health. In a world where medical resources are scarce, getting proper prenatal care would be difficult. She might face complications during pregnancy and have to rely on the limited knowledge of those around her.
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.
Well, perhaps the fanfiction could revolve around the mystery of who the father is. This could create a lot of drama and tension within the story. It could also lead to a search for the father, and along the way, Beth discovers more about herself and the people around her. Also, the pregnancy could force Beth to make some tough decisions regarding her future and the future of the baby.
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.
I hope not. Incestuous relationships are not acceptable in society and are quite disturbing. Fanfiction should also adhere to basic moral and ethical boundaries.
Definitely not. Abuse is a serious and often triggering topic. Even in the context of fanfiction, it can be very intense. It may not be appropriate for general audiences as it can cause discomfort, anxiety, or even trauma for some people who read it, especially if they have had personal experiences related to abuse.
Daryl and Beth have very different personalities. Daryl is the tough, brooding survivor, while Beth is more of the gentle, hopeful one. This contrast makes for an interesting dynamic in fanfiction. Writers can play with how they interact, support each other, and grow closer in the difficult world they live in. It gives a lot of room for creativity in exploring their relationship further.
Some Tumblr blogs are also dedicated to sharing and discussing fanfiction. You can search for relevant tags such as '#BethGreene #OlderMan #Fanfiction' on Tumblr. But keep in mind that the content on Tumblr can be a bit unorganized compared to dedicated fanfiction platforms, so it might take some more time to find exactly what you're looking for.
