Out of all the “Westworld” episodes so far, it seems like the ninth installment, entitled “The Well-Tempered Clavier,” dropped the most bombshells.

(Warning: Spoilers Ahead!)

The episode finally confirmed a long-standing fan theory that host Bernard Lowe (Jeffrey Wright) was created in the image of Dr. Robert Ford’s (Anthony Hopkins) dead partner Arnold.

Bernard finally had enough courage to confront Arnold about his past. He asked for a meeting and then had Clementine (Angela Sarafyan) point a gun at Ford. Bernard said Clementine would shoot if Ford does not provide him with all of his memories.

When he took a trip down memory lane, he recalled all of the nasty things Ford made him do, such as kill his former lover Theresa Cullen (Sidse Babett Knudsen) and associate Elsie Hughes (Shannon Woodward).

It was also revealed during the episode that Dolores Abernathy (Evan Rachel Wood) was the one who killed Arnold. Or at least, that’s what she was made to believe. Could Ford have tinkered with Dolores’ programming and made her kill Arnold? The two have such a positive relationship, so it’s hard to imagine her wanting to kill her creator out of spite.

Meanwhile, Maeve Millay (Thandie Newton) got a step closer to her freedom, and she enlisted the help of bandit Hector Escaton (Rodrigo Santoro). She confronted him in his camp and revealed his narrative before it even takes place. She also showed him the contents of the safe that he and his crew have painstakingly stolen, and he was disappointed to learn it was empty. It did not take much convincing for Hector to join her in her quest to go to “hell,” and they had sex while the camp burns around them.

As gripping as all those scenes were, nothing would ever compare to the chilling moment when Ford instructed Bernard to shoot himself.

The only theory still waiting to be confirmed is William (Jimmi Simpson) eventually turning into the Man in Black (Ed Harris). In this episode, his brother-in-law Logan (Ben Barnes) taunted Dolores' existence as he provided William with a picture of his wife. To recall, it was the same lost photo Dolores’ father Peter saw in the pilot. Seeing it made him go defunct, according to Romper. It was also what spurred the saying, “These violent delights have violent ends.”

William was devastated as he watched Logan thrust a knife into Dolores and opened her up to show her true reality. Thankfully, she managed to escape and went looking for Arnold. Something snapped within William after that scene, and he later threatened Logan to go help him find Dolores.

“Westworld” airs every Sunday at 9 p.m. EST on HBO.
