If Westworld season 2's multiple timelines are making your head hurt then you're definitely not alone. Following the big twist that Westworld season 1 was actually depicting three separate time periods, the sci-fi show's second season has kept up the mind-bending jumps back and forth in time as it explores the aftermath of the season 1 finale. We've seen more of Arnold's interviews with Dolores from before the park opened, found out more about happened to William and Logan after their grim journey through Westworld, and been introduced to new mysteries like the nature of "The Door" and "The Valley Beyond" - which may or may not be the same thing.

Not only has Westworld season 2 opened up more places on the timeline, it's also expanded the scope of the park to include locations like Shogun World and The Raj. The main characters are scattered across the map and the episodes are scattered across time. To help you keep it all straight, we've put together a guide to Westworld's timeline and what major events took place when. The dates given are derived from an Easter egg on the Delos website, which confirmed that the date of the host uprising in Westworld's season 1 finale was June 15, 2052.

Westworld's Origins (2015-2020)

The very earliest scenes that we've seen in Westworld are the interactions between Arnold and Dolores during the park's development phase, before it opened. Arnold became obsessed with the idea of guiding Dolores and the other hosts towards true consciousness.

During this development stage, when Robert Ford and Arnold's work was still being kept top-secret, the two inventors take a selection of hosts out of the park. They set up a tech demonstration for Logan Delos , who is floored by the lifelike hosts and seduced by Angela.

Shortly before the park opens, Arnold believes that he has made a breakthrough with Dolores that proves the hosts are capable of true consciousness, and tries to convince Ford not to open the park. His attempts at persuasion fail, and so Arnold tries one last desperate gambit to prevent the park from opening: he melds Dolores' mind with that of a villain character, Wyatt. With Teddy's help, she goes on a rampage through the park, slaughtering the hosts and finally killing Arnold himself by shooting him in the head.

After the massacre, a Ghost Nation warrior called Akecheta comes across the bodies and discovers the maze puzzle that Arnold gave to Dolores in order to help her "wake up." The maze sparks the beginning of Akechata's own journey towards self-actualization.

Unfortunately, Arnold's sacrifice fails. The park opens, but due to the enormous expense of building and maintaining the hosts, it faces financial difficulties that threaten to close its doors again.

Westworld Seeks Funding (2020-2025)

Evan Rachel Wood and Jimmi Simpson in Westworld Episode 7

Logan visits Westworld enthusiastically in its early years, but is unable to successfully convince his father, James Delos, to invest in the park. Somewhat understandably, Delos does not put much faith in the business acumen of his spoiled party boy of a son.

During this time, William enters the scene. A mid-level employee of Delos, Inc., William gets a promotion to an executive position after he becomes engaged to James Delos' daughter (Logan's sister). Logan welcomes his brother-in-law-to-be into the family by taking him on his first ever trip to Westworld. This trip is one of the major storylines of season 1, showing William gradually falling in love with Dolores as she gets pulled off her usual scripted loop and travels with William and Logan all over Westworld.

After Logan stabs Dolores and exposes her insides to William as a reminder that she's simply a robot, Dolores staggers away and William's journey into darkness begins. He slaughters the Confederados, ties Logan naked to a horse, and begins a bloody rampage across Westworld in search of his lost love. When he eventually finds her again, however, he sees her drop the same tin can that she dropped on his first day in the park, and realizes that what seemed like a random act was actually a programmed manipulation. He decides that this means everything he shared with Dolores was merely manipulation, and his heart hardens against her and all of the park's hosts.

Akecheta finds Logan out in the desert - naked and ranting that "this is the wrong world" and that he needs to find "the door." Akecheta gives him a blanket and tells him,"your kind will come for you." Later, Akecheta recalls that Logan's words "cracked something open in me."

However, William is still deeply interested in Westworld and its potential. He convinces Delos to invest in the park on the basis that it is an incredibly useful marketing research tool - allowing them to observe its extremely wealthy guests when they believe no one is watching them. Delos is convinced by the pitch, and Westworld is saved.

Westworld Under Delos Control (2025-2051)

Westworld - William and Delos

With the revelation that William and the Man in Black are one and the same person out in the open, Westworld season 2 is free to explore the years between young William's first trip to the park, and the "present day" scenes. We learn that William's exploration of the park's possibilities wasn't limited to marketed research; he also began working on a way to achieve immortality by putting a human mind in a host body.

It's during this time period that we see flashback scenes in which William interviews Dolores and treats her coldly, calling her a "thing." He takes her to a remote place in the desert where some kind of massive project is being embarked upon. We eventually learn that this project is the Valley Beyond/Glory/The Door/The Forge - different names for a facility where guest data is stored and then used to create AI versions of the guests.

We see James Delos' retirement party, where Dolores is playing the piano. Delos pressures William to speed up the immortality project. At this point in time, William is married to Delos' daughter and William's own daughter, Grace, appears to be about eight years old.

Some time after this, Delos dies and William begins trying to replicate his mind inside a host body. We see two conversations between the younger William and the host version of Delos, with William using the same dialogue to try and establish a baseline . Every time Delos realizes that he is a host, his cognitive functions begin to deteriorate.

At some point during this period of experimentation, William's wife kills herself by overdosing on pills and drowning in the bathtub. Logan also overdoses and dies.

Circa 1951, William murders Maeve's daughter in order to discover the darkest thing that he is capable of. This act leads him to the discovery of The Maze, and begins his obsession with solving what he believes to be a hidden game inside Westworld. Maeve is unable to recover from the death of her daughter, and has to be reassigned to a new role as the madam of the Mariposa Saloon.

Around the same time (it's unclear whether it's before or after), William visits Delos one last time - the 149th attempt at perfecting a means of immortality. He no longer has any hope that such a thing is possible, and instead uses the attempt to muse that perhaps no one is meant to live forever. After revealing the truth to Delos (including the revelation that both of his children are dead), William leaves the human-host hybrid to go insane in his plastic prison .

Westworld Season 1 (2052)

The "present-day" scenes of Westworld seasons 1 and 2 take place in 2052 and lead up to the fateful events of June 15, 2052. Over a period of time (what appears to be either a few weeks or a few months), several major storylines are taking place concurrently.

Ford is planning some kind of new narrative, but keeping the details to himself. He has recently updated some of the park's hosts to include a new quirk called "reveries" - allowing them to retain unconscious memories from their past lives in order to make them more lifelike. Some of the park's hosts begin to malfunction as a result of these reveries.

During this time, Maeve wakes up while in the Mesa Hub workshop and is exposed to the truth behind her world. Her knowledge of the truth persists even after having her memories wiped, and with the reluctant help of Westworld techs Sylvester and Felix she learns more about the park and begins plotting her escape.

William embarks on his quest to find The Maze, first recruiting Lawrence for the journey and then, after finding Teddy Flood near death, sacrificing Lawrence for his blood and dragging Teddy the rest of the way.

This eventually leads William to cross paths with Dolores, who has been retracing her steps from her journey with William several decades ago as she too searches for the center of The Maze - though without consciously realizing it. They clash in the graveyard outside Ford's newly-uncovered church, and engage in a brawl that ends with William stabbing Dolores. She is found by Teddy, and she pleads with him to carry her to "where the mountains meet the sea."

At some point during all of this, Bernard went to the secret lab where Delos was being held. He obtained a control module for another human-host hybrid in the park, before slaughtering all of the techs and drone hosts working in the lab .

Westworld's New Narrative Begins (June 15, 2052)

 Dolores shoots Ford in Westworld

Teddy carries Dolores to where the mountains meet the sea, and she dies dramatically in his arms. The lights come up and applause rings out, revealing that this is actually the introduction of Ford's new narrative, which he has dubbed "Journey Into Night." Delos board members, including William, celebrate at a reveal party that culminates in Ford giving a speech. The speech ends with Dolores, whose mind is once again fused with that of the Wyatt character, shooting Ford in the head. This is the trigger for the hosts to rise up and begin slaughtering the guests.

While all of this is happening, Maeve is carrying out her escape plan. She liberates and recruits Armistice and Hector, and they shoot their way through the Mesa Hub. Maeve reaches the train station and gets on the train that will take her to freedom, but at the last minute she decides to stay in Westworld and search for her daughter.

The Immediate Aftermath (June 15 - June 29, 2052)

As the "Journey Into Night" party descends into chaos and bloodshed, William manages to survive and - after meeting Ford's robot version of his younger self - discovers that Ford created a game for him called The Door. He embarks on a search for The Door, once again recruiting Lawrence as his sidekick along the way.

Dolores is now a combination of Dolores and Wyatt, and with a cult at her command she stalks through Westworld exacting grim revenge on the human guests and recruiting allies in her search for something called The Valley Beyond, which she believes is a weapon that will allow her to take over not only the park, but the outside world as well. After tinkering with Teddy's stats to make him less compassionate and more of a cold-blooded killer, Dolores launches an attack on the Mesa Hub and comes away with Peter Abernathy's control unit - the key to unlocking "The Door." However, on the journey to the Valley Beyond, Teddy kills himself in order to be free from Dolores' manipulation.

When the hammer falls, Maeve is in the Mesa Hub. She runs into Westworld's egotistical narrative director Lee Sizemore and forcibly recruits him in her search for her daughter, reuniting with Hector and later with Armistice, Sylvester and Felix. During an eye-opening visit to Shogun World, Maeve gains the ability to control other hosts telepathically via the mesh network that connects them all. She eventually finds her daughter, but almost immediately loses her again when Maeve is captured by Delos, and her daughter is captured by the Ghost Nation. Maeve is brought back to the Mesa Hub, and Delos finds a way to replicate her mesh network control within the lobotomized Clementine - enabling them to upload a virus to the hosts that forces them to kill one another.

The fallout from Ford's new narrative is not limited to Westworld. Both The Raj and Shogun World's hosts also go off-narrative, as William's daughter Grace discovers. She is chased over The Raj's border by a Bengal tiger and gets washed downriver to Westworld, where she is captured by the Ghost Nation. She escapes and eventually reunites with her father, but the reunion ends in tragedy when William - believing that Grace is a host created by Ford in order to trick him - shoots and kills her.

Bernard and Charlotte Hale end up together in the aftermath of the party, and Charlotte says that Delos will only send help if she delivers them a host - Peter Abernathy. While trying to retrieve Abernathy, Bernard is captured and dragged to a cave, where he finds missing tech Elsie, whom he choked up and chained up under Ford's instructions. Elsie and Bernard search the back of the cave and find an entrance to the lab where Delos is being held. They put him out of his misery.

Bernard's troubles do not end there, however. He and Elsie return to the Mesa Hub to investigate The Cradle - a place where a backup of every host in Westworld is held in a virtual reality version of the park. Inside, Bernard discovers that Ford created an AI version of himself, who then hijacks Bernard's body and forces him to kill several Delos security team members. Bernard and Elsie leave the Mesa Hub after Dolores' attack, and head for The Forge. Along the way, Bernard deletes Ford's code from his system and abandons Elsie to continue on his own.

In the season finale:

Bernard, William and Dolores convene at The Forge. William shoots Dolores multiple times in the torso, but she doesn't die, so he tries to shoot her in the head and a defective bullet causes the gun to backfire and blow off his trigger finger.

Bernard and Dolores enter The Forge, which has a system similar to The Cradle, allowing people to enter a simulated world. There, Bernard and Dolores meet an AI modeled on Logan Delos, who explains that every guest who has ever visited the park is stored in The Forge as an AI. He also reveals that the Valley Beyond is a "virtual Eden" - a new world unspoiled by humans, where the hosts can live freely. A drone host initiates the opening of The Door - a virtual gateway in Westworld that only the hosts can see. When they walk through The Door, their physical bodies are discarded and their code is transferred to the Valley Beyond.

Meanwhile, Maeve uses her psychic abilities to bring the corpses of the hosts in the Mesa Hub back to life. They kill the Delos team there, and repair Maeve's body. Maeve's friends arrive at the Mesa Hub to "rescue" her, and they all head to the Valley Beyond to search for Maeve's daughter. On the road, Delos catches up to them and Lee Sizemore sacrifices his life to give Maeve and the others a chance to escape. They reach the Valley Beyond and begin searching for Maeve's daughter, but as the hosts make their way to the valley, Clementine arrives on horseback. She has been loaded up with a virus that causes hosts to go insane and tear each other apart, and as she rides towards The Door chaos ensues. Ultimately, everyone in Maeve's gang is killed trying to give Maeve's daughter enough time to reach the Valley Beyond. Maeve uses the last vestiges of her strength to temporarily freeze the rioting hosts, and then dies in peace as her daughter escapes.

Dolores reads a few of the books of human code in the Forge's massive library, and then exits the Cradle and begins the process of deleting the guest data from the Forge and flooding the valley. Bernard shoots Dolores in the head and cancels the data purge. He then removes Dolores' control unit from her head, and replaces it with Abernathy's control unit. He leaves the Forge, and reconnects with Elsie and Charlotte as the valley begins to flood. They return to the Mesa Hub.

When they get back, Elsie tells Bernard that he is out of control and orders him to stay sat in a chair. She then meets Charlotte in the map room below and offers to play along with Delos, but Charlotte says that Elsie is not morally flexible enough and shoots her dead. Bernard calls upon Ford (who actually turns out to just be a hallucination) to free him from the chair, and then builds a host body that looks exactly like Charlotte Hale and puts Dolores' control unit inside it. Dolores - who now looks exactly like Charlotte - kills the real Charlotte and takes her place.

Bernard goes to the beach and scrambles his memories so that Delos will not be able to find out what he did through interrogation.

Two Weeks Later (June 29, 2052)

Westworld season 2 - Delos security

Bernard wakes up on the beach and is discovered by Stubbs, who introduces him to Delos COO Karl Strand . Delos has sent reinforcements to retake the park, indicating that Charlotte was successful in delivering Abernathy to them. In the water off the coast of a beach, Bernard and the others discover bodies of hosts floating - among them, Teddy Flood. Bernard says, horrified, "I killed them all."

Later, Stubbs and Bernard are taken to the workshop where Theresa Cullen was killed by Bernard (under Ford's orders) in season 1, and Strand and Charlotte discover a room full of previous Bernard models - exposing him as a host. Bernard is interrogated about the location of Peter Abernathy's control unit, and reveals that it's in The Forge. He, Strand, Charlotte, Stubbs, and the rest of the Delos soldiers head out to retrieve the extremely valuable data.

In the season finale:

They group reaches The Forge, and finds Dolores dead from a gunshot wound to the head. Strand recovers Abernathy's control unit from Dolores head, and the Delos tech gets ready to transmit the data to the mainland via satellite. However, just as he realizes that the data package is far too large to contain just the guest data, Dolores reveals herself and kills everyone in the room except for Bernard.

Dolores transmits the Valley Beyond and the surviving hosts to a secret, safe location on the mainland via Delos' satellites, and then shoots Bernard. She takes the control unit from his head, along with four other control units, and heads for the evacuation point. As she makes to leave, Stubbs halts her and reveals (rather cryptically) that he was a host all along. He waves her through security, and Dolores escapes Westworld.

William is revealed to have survived, and is lying unconscious in one of the tents awaiting evacuation.

She goes to a safe haven that Ford built for her on the mainland and builds a new body for Bernard. After being awaken, Bernard leaves and takes his first steps into the real world.

The Distant Future

Westworld season 2 finale post-credits scene

In the season finale's post-credits scene, William gets out of the elevator in The Forge and finds the place in ruins, and his daughter (or rather, a host version of her) waiting for him. It's clear that some time has passed since the rest of the season finale. Emily tells William that she is there to verify his fidelity, indicating that the version of William we see here is also a host.
