Warning: Spoilers ahead for the season two finale of HBO's "Westworld."
The second season finale of HBO's "Westworld" introduced new mind-bending turns to an already complex story (and timeline). From the violent revelation of Dolores disguised as Charlotte Hale to a significant end-credits scene you might have missed, the 90-minute episode was packed with major moments.
Keep reading for a look at nine of the smaller details in the finale you might have missed.
When Dolores and Bernard entered the Forge, we learned about a new data copying system.
Each guest's data code was transcribed into a book by a robotic arm. The first book we see belongs to the code for James Delos, and it was stationed on an old-fashioned music stand.
This is a callback to a quote from Dr. Robert Ford on the first season finale.
"An old friend once told me something that gave me great comfort," Ford said. "Something he had read. He said that Mozart, Beethoven, and Chopin never died. They simply became music."
When Dolores flipped through one of the books, you can see how the markings of data look just like sheets of music on a player piano.
Just as Ford became music, the guests who visited the park have become music. This little detail was shared on the "Westworld" subreddit by user Kotn3l.
For comparison, here's the player piano sheet music shown in the weekly opening credits on "Westworld."
Forge-Logan says "the truth is that a human is just a brief algorithm — 10,247 lines. They are deceptively simple. Once you know them, their behavior is quite predictable."
Dolores was able to quickly scan and memorize the humans' algorithms in order to give herself an advantage over the species (aka the weapon she had been seeking).
