In the PLL fanfic, when Caleb gets sick, it could lead to a lot of worry among his friends. They might try to take care of him, like Hanna bringing him soup and making sure he takes his medicine.

The story would change in several ways. First, the focus would shift a bit to Caleb's health. His friends would be preoccupied with taking care of him.

A common theme might be the re - imagining of Caleb's character arc. In the original PLL, his relationships are mainly heterosexual. In gay fanfic, it could be about how his relationships with male characters develop over time. It could also include themes of friendship turned into something more, and how that impacts the overall PLL storylines that are re - written or expanded upon in the fanfic.
