The main character aside from Arthur could be an adult who has a special connection to the PBS world. Maybe this adult used to watch Arthur when they were younger and now they get to meet him in this fanfic. This adult could introduce Arthur to different aspects of the real world that are more relevant to grown - ups, like different jobs or how to manage finances.
It could be a child. Since Arthur is often associated with kids' shows, it would make sense for him to meet a young human, like a school - age child.
In the 'arthur pbs meets a human fanfic', it could be that Arthur and the human become friends.

Well, in the 'arthur meets a human fanfic', it could be that Arthur initially has some misunderstandings with the human. But as the story progresses, they start to understand each other better. The human could introduce Arthur to human culture, like different kinds of music or food. And Arthur could show the human some unique things from his own world. For example, if Arthur has some special abilities, he could use them to help the human in a difficult situation. Maybe they end up having a strong bond that crosses the boundaries between their different existences.
