"Westworld" has more characters and storylines than the average viewer can keep up with, so we've assembled a handy character list for your Sunday nights.
We'll update this slideshow as new characters are introduced each week, but for now the spoilers only cover through season three, episode two.
Let's dive in.
First up — Dr. Robert Ford.
Ford was Westworld's park director and one of its co-founders. The process for creating and programming the hosts is all based on his team's original research conducted over 30 years ago.
On the first season finale, Ford was shot and killed by a host named Dolores.
Ford also build a young host-version of himself who lives in the park.
This host speaks with a blend of Roberts old and young voice, and is coded to continue representing Ford in the park.
Dolores Abernathy is the oldest host in Westworld.
Since she's the oldest park host, that means Dolores was created over 35 years prior to the events in "Westworld."
Stubbs says that she's been updated so many times "she's practically brand new." Dolores was one of the first hosts to get close to sentience. By the end of the first season, it appeared as if she was finally self-aware when she shot and killed Ford.
Arnold was Ford's original partner and co-creator of the hosts.
Arnold was the one who began experimenting with bootstrapping consciousness into the hosts. Dolores was his first test subject. He created a "maze" inside the park to help lead Dolores into self-awareness and to spur the creation of a subconscious mind in her.
He eventually decided Westworld shouldn't open, because the hosts were starting to become sentient. Arnold programmed Dolores to kill all of the other hosts as well as himself in an effort to sabotage the park.
Bernard Lowe is a host Ford built in the image of Arnold.
Bernard was Ford's right-hand man, a host who is the the Head of Behavior and a programming specialist. Bernard was programmed to think he was human, but over the course of the first season he learned the truth.
Karl Strand is the head of operations at Delos.
He's a no-nonsense kind of man who was sent by the Delos company to fix the mess in the parks after Ford's new bloody plot wreaked havoc.
Elsie Hughes is a Behavior Specialist who worked under Bernard Lowe.
Elsie helps with coding, debugging, and processing the hosts as they receive updates. She was working with Bernard to investigate host glitches when she disappeared. Now we're not sure where in the park she is, but we're pretty sure she's alive.
Antoine Costa is a technician who is not missing, but is helping Strand analyze the hosts in the field.
He first appeared on the second season premiere, where he extracted a cortical storage device from a host and showed the Delos team the video footage kept there.
Ashley Stubbs is the Head of Security for Westworld.
Stubbs has a healthy level of skepticism when it comes to the hosts following their programming, and tends to take on potentially risky retrieval missions himself.
Maling in a new Delos security personnel character.
She also first appeared on the opening episode of the second season, where she found Bernard and helped Strand keep the new system in order.
Lee Sizemore is the ambitious Head of Narrative at the parks.
Most of the storylines and dialogue you see the hosts act out in the park are all Sizemore's design and script. He was helping the Delos board smuggle data out of the park by the end of the first season.
Theresa Cullen was the Head of Quality Assurance.
It was Cullen's job to make sure the guests are happy and the hosts are behaving according to regulations. But Theresa was secretly helping the Delos board smuggle data out of the park.
Ford had Bernard kill Theresa on his orders and make the murder look like an accident.
Charlotte Hale is the executive director of Delos and Westworld's board.
Her friendly demeanor gives way to a stern and calculating woman who has been smuggling data out of the Westworld park. Though she hadn't yet revealed specific details about the data on the first season, we're sure her secrets will eventually come out.
Maeve Millay is one of the first newly sentient hosts in Westworld.
Maeve was the madam of the Marisposa — a saloon/brothel in Sweetwater. Now she's the most powerful host in the park, and has the ability to control other hosts with voice commands.
Felix Lutz is one of the Livestock Management employees.
It's Felix's job to patch up the hosts after they've been shot, stabbed, or otherwise incapacitated. But Felix "borrowed" a coding console from the behavior department and wound up helping Maeve change her core programming and enabling her to escape.
Sylvester is Felix's partner in the Livestock Manufacturing lab.
He had no patience for Felix's experiment with coding, but was roped into the Maeve-escape plot after she threatened his life.
Clementine Pennyfeather was one of the host prostitutes working at the Mariposa under Maeve.
She specialized in finding newcomers and welcoming them to Westworld. But after Charlotte and Theresa used Clementine as a scapegoat host in a failed experiment, Clementine was lobotomized.
Teddy Flood is another host with a troubled past and a penchant for gunslinging.
He often accompanies guests on bounty hunts, or tags along with his programmed love — Dolores. Teddy's primary directive is finding and helping Dolores, though his good-natured side can be manipulated via coding.
Angela is a host we've seen in two roles — a greeter for new guests and as a henchman for Dolores.
She's one of the oldest hosts in the park, along with Dolores and Teddy. She's currently acting as a rallying point for the other rebelling hosts who will support Dolores (as "Wyatt").
Akecheta is another of the original hosts in the park.
He went with Angela to first pitch Westworld to Logan Delos.
Major Craddock is another host, though his current role is as a dangerous leader in the Confederado.
We saw this host first appear at the party with Angela and Akecheta, but he was without a mustache then. Later, Dolores meets this host while he's in his solider narrative.
Logan Delos is a powerful businessman who was looking to increase his company's stake in Westworld.
Logan is an ambitious and impetuous bad boy who loves indulging in his vices while visiting Westworld. The scenes featuring Logan on the first season all took place around 30 years prior to "current day" on "Westworld."
James Delos is Logan's father and the titan of industry.
James is a no-nonsense man who seems impatient with his son. But James' daughter, Juliet is dating another promising young man.
William is Logan's future brother-in-law and his coworker.
William came to the park with Logan to celebrate their future lives as in-laws. But by the time they left, William decided to usurp Logan's role in the company and go work with James directly.
The Man in Black is William, but in "present day."
William transformed into the Man in Black by the end of the first season. By current day on the show, William is one of the most powerful Delos board members. His wife (Logan's sister) has committed suicide, and after their daughter blamed William for her death he returned to Westworld to confront his demons.
Juliet is Logan's sister and James' daughter, and eventually William's wife.
Juliet marries William and they have a daughter, Emily, together.
Emily is the daughter of William and Juliet.
She was first seen in The Raj park, but after the rebellion began Emily found herself in Westworld and reunited with her dear old dad.
Lawrence/El Lazo is a host who spent most of season one with William.
He's referred to by other hosts as an outlaw due to his criminal group run under the name El Lazo. Lawrence is a sardonic host who often winds up tagging along with William on his dangerous adventures.
Hector Escaton is the "bad boy" host of Westworld .
Hector is a bandit who travels with a group of loyal followers and periodically tries to rob the Mariposa Saloon. He teamed up with Maeve after she showed him the truth about how the park works and their role in it.
Armistice is Hector's host companion and fellow gunslinger.
Armistice has a deadly shot and a gigantic snake tattoo covering her body — the relic of a tormented past. She also joined Maeve's escape mission and is becoming more self aware.
Akane is the host-equivalent of Maeve in Shogun World.
Akane is a geisha who has a beloved companion, Sakura, just as Maeve had Clementine at the Mariposa Saloon.
Musashi is a former captain turned ronin who helps Akane and Maeve.
Mushashi is another of the main Shogun World hosts we met on season two. He used to be the captain of the Shogun's army, but left and turned rogue. He and Hector are on similarly designed narrative structures.
Season three kicks off with the introduction of many new characters, including Caleb Nichols.
Caleb is a construction worker living in Los Angeles, and he encounters Dolores by the end of season three, episode one.
Francis is Caleb's old friend and army buddy.
In the premiere of season three, we see Caleb talking frequently on the phone with an AI version of Francis, voiced by Scott Mescudi aka Kid Cudi.
Liam Dempsey Jr. is the head of Incite.
Liam is the head of Incite, a data tracking company that helps control major aspects of people's lives — everything from traffic control to career pathway determination.
Martin Connells is the head of security for Incite.
He makes sure Liam and all the other Incite employees are safe and secure and not messing things up too badly.
Ash is the pseudonym used by one of the people Caleb does his petty crime jobs with.
Caleb meets up with Ash to help rob an ATM in the season three premiere of "Westworld."
Giggles is another petty criminal who has worked with Caleb.
Giggles and Ash seem to come as a pair, and both work with Caleb on various criminal enterprises.
Enguerrand Serac is a mysterious trillionaire who helped create Rehoboam.
Serac is both the person currently controlling the Incite algorithm system and one of its original creators. As revealed in the third episode, Serac has also been using his powerful anonymity to try and control Delos from the shadows.
He now owns a controlling stake in the company and has been using Charlotte as a mole for corporate espionage after she sold him some of the park's data 20 years ago.
Martel is Serac's high-ranking associate.
Martel is the one who had a face-to-face meeting with Liam Dempsey, Jr. in the first episode of season three. She seems to be the primary connecting link between Serac and anyone he wants to speak to (with the exception of Maeve).
