A quick guide to every major character in 'Westworld'

We saw this photo of a younger Ford and Arnold in episode three, when Ford was telling Bernard about the other co-founder of Westworld. Arnold allegedly killed himself inside the park right before it opened over 30 years ago.

Lowe appears to be Ford's right-hand man — the two often discuss the hosts and their coding updates. Bernard had a young son, Charlie, who died of unknown causes. He video chats with his (possibly) ex-wife, and is engaging in an affair with Theresa Cullen.

It's Cullen's job to make sure the guests are happy and the hosts are behaving according to regulations. She also appears to act as a liaison between Westworld's Board of Directors and Ford.

Elsie helps with coding, debugging, and processing the hosts as they receive updates.

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.

Most of the storylines and dialogue you see the hosts act out in the park are all Sizemore's design. Based on recent events, however, it appears that Ford has the power to nix any of Sizemore's narratives and implement his own.

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 behavior and has been experimenting with doing his own programming on the side.

He has no patience for Felix's experiment with coding, and seems resolved to his role as a "butcher."

Maeve is currently the madam of the Marisposa — a saloon/brothel in Sweetwater. Maeve frequently lands on Felix and Sylvester's operating table.

She specializes in finding newcomers and welcoming them to Westworld.

Since she's the oldest park host, Dolores could have been manufactured up to 30 years ago. Stubbs says that she's been updated so many times "she's practically brand new." Dolores seems to be breaking out of her typical programming, though the cause is a mystery.

He often accompanies guests on bounty hunts, or tags along with his programmed love — Dolores.

The Man in Black has essentially been visiting the park since it opened. He's an expert player of the game, and gets special park privileges due to his mysterious V.I.P. status. We're pretty sure he runs a medical foundation of some kind out in the real world.

He's referred to by other hosts as a very dangerous man, likely due to his criminal group run under the name El Lazo.

While in Westworld he's more of a sexual deviant and murderous kind of guy. This trip he brought along his coworker (and soon-to-be brother-in-law) William.

Unlike his friend, William's more of a "white hat" kind of good guy who is predisposed to treating the hosts like humans. Back home, he works under Logan as the Executive Vice President at an unknown company.

Hector is a bandit who travels with a group of loyal followers and periodically tries to rob the Mariposa Saloon. Guests in the park can join his gang of ne'er do wells, or foil his plans of thievery by killing him.

Armistice has a deadly shot and a gigantic snake tattoo covering her body — the relic of a tormented past. As the Man in Black learned, her tattoo might be a clue about the mysterious maze hidden inside the park.
