Remember when Arthur first encountered the Vogons, and wished he had a daughter so he could tell her never to marry one? In this book, he ends up with Random. Be Careful What You Wish For, Mr. Dent.
Arthur Dent becomes the village's esteemed Sandwich Maker. The Subway restaurant chain dubbed their sandwich makers "sandwich artists".
Inferred Holocaust: The destruction of "every Earth in every reality" and all their inhabitants sounds bad enough, but it's left to the reader to realize that that includes NowWhat, the King, and probably even the dolphins. (NowWhat may be a Crapsack World, but it puts a human face on those alternate Earths and shows just how diverse they were.)
