Were William and Myra important to the story?

[Asja Šabani]

William and Myra were important characters because they were sources of a lot of important information for Sarah and for the readers. William also offered a pretext for introducing the Russian scientist. However, we were given too many unimportant details about these too, for example, many remarks about William's hurting feet.

Well, I don't think Tom would've gone camping with Sarah without being pushed by William, so there's that. Tom seemed sort of lackadaisical about a lot of things and they usually got him moving/acting, and I think he needed them there to help him figure out his new granddaughter. Their knowledge of the folklore and legends of their tribes turned out to be pretty important too.

Good point. Thanks for the comment
