Trivia: Nate's dad, played by Thomas F. Wilson, says "let's make like a tree and leave", to which Nate replies "I'm not sure that's how it goes." Thomas F. Wilson famously played Biff in the Back to the Future films, who frequently got that saying wrong.
Trivia: Dolores tells William: "They say great beasts once roamed this world, as big as mountains, but all that's left of them is bone and amber." This is a general allusion to dinosaurs, of course; but, more specifically, it's a tip-of-the-hat to "Jurassic Park," by author Michael Crichton, who also wrote The Original "Westworld." The theme of most of Crichton's science fiction was human shortsightedness resulting in scientific nightmares. Crichton's "Westworld" and "Jurassic Park" are virtually identical stories about scientific amusement parks running amok.
Trivia: When Dirk and Todd are talking about if Dirk ever solved a case, he mentions there was a bit about a sofa and Thor. This is a reference to the first two Douglas Adams' book in the Dirk Gently series, "Dirk Gently's Holistic Detective Agency" (which had an immovable sofa) and "The Long Dark Tea-Time of the Soul" (which had Thor).
