First I was thinking it might be some kind of a virus, or maybe it was the real Bernard delivering information to hosts in such a peculiar way, or maybe it was some force still not introduced into the show...
But this season the fly never appeared, so I forgot completely about it. Until it was shown once again in the pivotal episode with Akecheta.
Don't you remember? Those scenes were like crucial for the first season. They were almost like... I don't know... Kevin Spacey talking to the viewers in the 'House of Cards'.
These articles are like 2 years old, so I was guessing if there might be some new info or theories:
In episode 5, Dolores tested Teddy's weakness with the story of the "bluetongue", a sickness of cows spreading by the flies. Later when she was about to "burn" Teddy, she mentioned that the "bluetongue" event had happened when she was a girl.
Here is my interpretation of that:
Those flies were real, at least, in the beginning. Why there were flies in the westworld? As we could guess, where the tourists go, they left garbage and flies came. Make sense? Now, how did the cows get sick? Because when Dolores was a girl (She never was, it just means the early days of the park.) they use real cows. We saw Arnold handmade the first Dolores. Which would suggest that using real cows at that time was easier than handmade some robot cows. Later, when the bluetongue started spreading, the management allowed her father, Peter, to burn all real cows(the weak and the infected), and the herd saved were all robot cows. I guess that's the first time, Dolores learned about how fragile/weak the livings are.
The flies are always shown in such a way so that the viewers would notice them. And it's always just one fly btw.
How do you hide something big? Apart from the obvious of course and that is putting it right in front of somebody's eyes. You disguise it as something small, insignificant. Everyone was a child once, everyone remembers the events of 'Puss in Boots', so this is relatively easy.
So the fly is actually something big. What's that? No clue.
But taking all that straight-forward biblical symbolism we've seen in the finale (Jews wandering through the desert, the parting of the Red sea etc.) my guess is that the fly could be probably connected to the 'Lord of the flies' character.
I think you have it right, the fly was originally meant to explain how Ford was communicating with the hosts without the park knowing but somewhere along the way it was dropped.
Why do you say it was dropped? We see it in episode 8 this season.
My guess it's just some kind of a slow-burning storyline that goes across several seasons. Not sure if it will be explained even in season 3.
Well, that was in my original post ;)
Akecheta episode, the fly is crawling over his hand. This happens around the moment Akecheta gains the understanding of how things work in the park.
I just thought they showed how when the hosts didn't have consciousness they didn't care about the flies being on them, but when they gained consciousness they swatted at them as a living person would. but, that would be really cool if the flies were used to transmit the "virus" that leads to consciousness.
