How does the author use foreshadowing in Lords and Ladies: A Novel of Discworld?

When the Lancre Morris Men are set to put on a play, some of them are perplexed by the fact that they will have to dress up as women. The men are embarrassed at the idea of rehearsing this in public, and are already brainstorming on out of the way locations in which to practice. This foreshadows their eventual uses of the Dancer.
