Davidson does not write in depth about her family relationships, but her mixture of happiness and sadness upon seeing them here indicates that she has, on some level, come to terms already with the idea that other people can be positive presences and negative presences at the same time (and also hints at unspecified reasons she decided to take this trek in the first place). This duality appears again when she sees Rick; he’s a friendly face, but he’s also an irritation. Davidson’s moment of wonder at the world around her also hints at the understanding she will come to later in her journey, when she sets aside the order of civilization in exchange for the peaceful balance of nature.
