Maybe in the fanfic, Althea and Alicia discover a hidden community that has a cure for the walker virus. But they have to fight against the community's leaders who are corrupt. Althea records the evidence of their wrongdoings while Alicia tries to rally the other survivors to fight for the cure.
In the fanfic, Althea's character can be developed through her relationships. She could form a closer bond with Alicia, and this could change her from being a more solitary documentarian to someone who is more involved in the group's survival. Alicia, on the other hand, could develop her strategic thinking by working with Althea. Althea's unique perspective might make Alicia see things in a new way, leading to her making more calculated decisions in dangerous situations.
Definitely. Abraham's death was a significant event in the comics. It happened during a tense and dangerous situation that had major implications for the story.
