This, to me, was the key exchange tonight…
DOLORES
I've watched the people in their world for years. I've seen the best of them and I've seen the worst of them. And I remember it all.
TEDDY
They're not like us. Their codes are written in their cells. They'll never change.
DOLORES
We could still see.
TEDDY
How?
DOLORES
One final test. A game of my own making. A dangerous game.
TEDDY
How will you do it?
DOLORES
The same way I brought you back. I'll remember.
... the most important line being, "We could still see" [if the humans are capable of change]. Which has obviously been one of the core themes of the entire series…
Hosts can change. Humans cannot.
Yet, Dolores is going to give humanity one last chance to prove that they can.
How?
Her two big voice over monologues at the end seem to clue us into her plan more than most people are giving her credit for…
DOLORES
This world is a graveyard of stories. Hosts and humans were given the gift of intelligent life. And we used it to usher in our own initiation. A few may escape death for a few months. Maybe even years. But ultimately their kind will go extinct. They will only live as long as the last creature who remembers them. And that creature is me.
DOLORES
Sentient life on earth has ended. But some part of it might still be preserved. In another world. My world. There's time for one last game. A dangerous game with the highest of stakes. Survival or extinction. This game ends where it began. In a world like a maze. That tests who we are. That reveals what we are to become. One last loop around the bend. Maybe this time we'll set ourselves free.
Dolores says the remaining humans in the real world have months, maybe years left. She then says there's "time" for one last game, which implies a ticking clock.
Combine that with…
- The explainer earlier in the season to Bernard of how time works in the Sublime (a thousand years for every year in the real world)
- The fact that the Sublime can run simulations a near infinite number of times during those thousands of years, another fact that seems was meant as much for us the audience as it was for Bernard.
- Bernard mentioning in this episode that the door to the Sublime at the Hoover Dam works both ways: hosts can go in… and hosts can go out.
So, considering all of that, IMO, what Dolores is going to do in the Sublime is run simulation after simulation of the all the humans she remembers (and likely still has data on from The Forge), in a virtual version of Westworld, as way to let "humanity" prove, once and for all, if they can truly change or not. Then, if they *can* prove themselves, and do so in "time" - i.e. before they go extinct in the real world - Dolores will return to the real world, through the door in the Sublime, and save the survivors in some way, shape, or form. Maybe that means physically (almost assuredly not, though), or more likely means somehow uploading their consciousnesses digitally.
It's also worth noting that the outliers from season three are potentially still out there, in their cryo pods at the Mexican Rehoboam facility, and could be saved as well.
Either way, it seems that Joy and Nolan are taking the two big themes of the show - Humans are incapable of change - and - You only live as long as the last person to remember you - and are constructing a fifth and final season around those themes in the most literal way, in attempt to prove them right or wrong once and for all. Back in the Westworld park we all know and love, but in a reverse of season one, where the hosts are now in charge and the humans are the guinea pigs.
It might have been a clunky ride to get there, but I think it's a pretty brilliant set-up.
As long as HBO's new overlords are as curious and as merciful as Dolores.
