They could use their odd knowledge of their home town to guide the child through the city.
Tubbs' over - the - top fashion sense and her pride in her appearance can be a big part of fanfic. Maybe in a story, she loses her favorite hat and goes on a wild search for it, dragging Edward along. Edward's loyalty to Tubbs is another characteristic. No matter how crazy her ideas are, he usually sticks by her side. This loyalty could be put to the test in a fanfic, such as when they meet someone who offers Edward a better life away from Tubbs.

Maybe there's a plot where a spell in the Harry Potter world goes wrong and somehow transports Edward into Hogwarts during a Muggle Studies class. Harry has to figure out how to send him back while also dealing with the chaos that Edward's presence causes among the students, especially the female ones who are attracted to him.
