This post contains frank discussion of Westworld season three, episode five “Genre.” If you’re not all caught up, now is the time to leave.

The big revelation of this episode has to do with Aaron Paul’s character Caleb Nichols and the very illuminating drug trip he experiences while kidnapping Liam Dempsey Jr. (RIP). For an exhaustive rundown of his genre-hopping journey and those confusing flashbacks at the end check out the rundown below. All season, Vanity Fair’s Still Watching podcast will have weekly breakdowns of the episodes, which you can find here.

But let’s get on with some of the nitty-gritty musical details you might have missed.

Caleb, gets dosed with a party drug called “Genre” that Liam still had in his pocket. Last week Liam’s pal Roderick (Rafi Gavron) promised the pill would take him to the “silent era” and back. Caleb didn’t go quite that far back in film history, but his trip did take him through five distinct genres of film over the course of the episodes. Because the camera work didn’t change too much beyond the black and white section that kicks off the drug trip, Westworld employed famous movie musical cues to give audiences a hint as to which genre Caleb was experiencing at any given time. The whole trip culminates in a final genre that gives both Caleb, and us, a big hint about his mysterious path so let's take a quick musical journey on our way there.
