The opening scene shows Dolores speaking to Arnold.
Arnold – one of the co-creators of the Westworld park — had conversations with Dolores in this exact room setting and while wearing these exact clothes. We saw many flashbacks to those talks on season one.
But is this really Arnold? Or could it be Bernard, the host Ford built in Arnold's image? There's also the possibility this is Dolores having a conversation with her subconscious, the way she did throughout the first season. But for now we're pretty sure it's Arnold.
And the dream he discusses with Dolores is eerily prophetic to how the episode ends.
At the end of the episode, Bernard is standing at the edge of a sea and looking out on a swath of drowned hosts.
This final shot implies that in the two weeks between the start of the rebellion (aka the final moments of season one) and when the Delos security team arrives at the park, Bernard came to the decision to "kill all of them" (the hosts).
In the opening scene, Arnold (or Bernard?) told Dolores about a dream he had.
"I dreamt I was on an ocean, with you and the others on the distant shore," he said.
"Were you with us?" Dolores asked.
"No. You'd left me behind," he replied. "And the waters were rising around me."
Which brings us to the recurring idea of "The Valley Beyond."
This phrase first came up when the Delos security detail pulled the video footage from the dead Native American host. The video log showed Dolores shooting and killing the host after saying, "I told you friend, not all of us deserve to make it to the Valley Beyond."
This phrase came up several times on this episode, and it's likely connected to the ocean of dead hosts seen at the end.
