What in the 'Westworld' Happened Last Night? We've Got a Man in Black Theory and More Questions After Episode 4

Episode 4 has come and gone, and it was about as dense as they come -- a lot to unpack, and if you stole even a single glance at your phone (and we know you did), it probably felt like you missed the last handful of episodes and not just 10 seconds.

Plus, this was one of the best episodes of the series so far, so we hope you rewound and got your focus back, because we're about to get weird!

SPOILERS AHEAD!!!

Turns out, Grace isn't just like Rajworld's Man in Black (like we mentioned last week!) -- she's his daughter! That's right, the big reveal at the end of this episode is that Grace is William's daughter, the same one he keeps telling everyone that she hates him, and the one that found his wife's (her mother's) body after taking her own life.

We're excited to see what their dynamic is actually like now that they're reunited, but the biggest thing we want to know is: Are they on the same path? Did Ford put them in the same game, or is it coincidence?

Note: Her hat is grey, not black...

Symbolism!

If you watched "Lost" back in the day, you'll remember the clues scattered around each episode -- and specifically, the lab symbols. We're getting the same exact vibe in "Westworld." Did you catch that symbol with the number 12 when Elsie (who is alive!) and Bernard (Jeffrey Wright) went into the secret lab in the cave?

So help us if Teddy runs into a smoke monster at some point, we'll have trouble squealing with glee and rolling our eyes at the same time. But just like with "Lost," we're totally on board with the cryptic symbols. We're suckers.

Bernard pocketed a core that he made in that secret cave lab before turning all the drones on the humans inside -- and in this episode specifically, we've found that Delos (both the company and the man) were attempting to put actual downloaded brains into hosts. It's just a shame that even after all those years, they hadn't been able to crack it for Mr. Delos, as we only saw a stable version of him make it to day 35 after over 100 attempts.

Side question: Any guesses on how long it was between older William's final visit with Delos and when we see Elsie and Bernard enter the same room? William's been playing in Westworld for a hot minute, so we suppose that version of Mr. Delos had been deteriorating for quite some time -- though the dead technician in his quarters was the final one we saw begging to terminate him. Did William only begin his final foray into Westworld a short period before the massacre? There's so much happening that it's easy to assume that the William has been on his "final" trip to Westworld -- hunting for the end of the maze in Season 1, and then starting Ford's final game -- for months and months, but that might not be the case!

Back to the original topic, though: Whose core did Bernard pocket? Occam's Razor says Ford, but would that be too easy? Maybe it's for (gasp!) Arnold! Could the Bernard we see waking up on the beach actually be Arnold?

Also, another guess: White Mangosteen Brain = normal host core. Red Velvet Mangosteen Brain = human mind core.

We all just assume that present-day William is human, right? He likes to go on about how they're now finally playing for keeps, but what if that's a misdirection for us?

What if William's "maze" was just the beginning of his much larger test -- a bigger scale test we see him administering Mr. Delos? What if Ford is testing him specifically to get him onto a higher plane? To get him past his "you're a robot!" breakdown that Mr. Delos goes through?

What if Grace approaching her dad at the end was like William walking through the door for Mr. Delos?

Doesn't really explain all the stuff we've seen from Grace on her own -- like the notebook and stuff -- or why Ford would have to off himself and make things so elaborate just for one robot.

But still... think about it.

OK, let's get it out of the way: We were wrong that Elsie had a hand in the Ghost Nation. Well, we suppose she still might -- maybe they were her program project at some point -- but we think it's safe to say that she has nothing to do with the fact that they're not into killing humans, only hosts.

But, hell yeah! We were right about them not killing humans!

The whole judgment scene was interesting, because at first we were like, "OK, they're gonna kill some humans," but then they DIDN'T. The one Ghost Nation guy even spoke some English!

Oh, and fun fact: The lady who was giving her husband shit for bringing her to Westworld was from Season 1, early on. Great callback to how much time has truly passed (not a lot, even though we're not sure exactly how much).

So, are we going to find out what the Ghost Nation directive is soon? We hope so!

It feels like William is on a path to redemption, and after witnessing William's descend into darkness, Ford is attempting to teach him that there are more to hosts than just entertainment.

Let's think for a second about how we've seen William treat the wife and child from his partner's hometown in the past: He treated them almost exactly like Craddock did. This time around, though, something clicked inside of him and he had empathy for them. Ford talking through the daughter later on basically says as much but that William's one instance of mercy doesn't redeem him for everything that he's done.

Is the prize at the end of William's game a full-circle return to the man he was when he fell in love with Dolores and the park in the beginning?

The questions is: Why would Ford care so much about teaching William this lesson? Doesn't this more align with something that, say, Arnold would have done based on how he viewed the hosts?

So many questions! So many episodes left in the season! See ya next week!

P.S. The theory that everyone has been shrunk down to get inside Westworld is still alive! It'll be a sad day if it's ever debunked.
