"You said people come here to change the story of their lives," she says, chillingly, almost. "I imagined a story where I didn't have to be the damsel."
Even her voice is lower. She is officially a badass, and as a badass, also seems to know just what to do next, so she tells Will they have to catch a train, and they do. But upon entering the train car, they see El Lazo pointing guns at them, but Dolores knows all the tricks, so she points a gun at Slim's casket filled with nitroglycerin and El Lazo gives up and is like, "Damn, OK, well, now that we're all friends, you can call me Lawrence," further twisting the parallel narrative idea. And then Lawrence tells them to settle in for a long ride to the front.
So... the war front? Are they still going to war? Is Logan dead? If Logan is dead, could this be the beginning of the incident that the current-time Westworld workers keep referring to? And could this also explain how William gets out of upper-middle management and becomes enough of a baller to have a foundation, if he truly is the Man in Black?!
