Is Ford referring to the Man in Black here? Earlier in the episode, we learned that Ed Harris' maze-crazed cowboy is a wealthy man with a generous charitable foundation in the outside world. Perhaps he's the Delos representative out there beta-testing Ford's next narrative? Also, if you're still buying into the "William is the Man in Black" theory, this episode also featured Logan telling William that the family's business should increase its stake in the company. Is that hinting that the Man in Black got in on Westworld from the ground floor?
What do we know about Ford's final narrative at this point? Probably about as much as we know about where the plot of Westworld is going, which is very little. You can bet it involves the maze, the black church steeple, Wyatt, the creepy death cult, Teddy's haunted backstory, Dolores, and probably the Man in Black, but the show has been very careful not to tip its hand in any particular direction. Instead, like Hopkins, Jonathan Nolan and Lisa Joy are content to move their fingers slowly under the table, sending us all scurrying with even the smallest gesture.
