Teddy's would-be love is Dolores Abernathy, the oldest host in Westworld.
Actress Evan Rachel Wood's styled short hair is very strikingly different from her character's long blonde wig.
Dolores is currently tagging along with William — a compassionate first time guest in Westworld.
Though Jimmi Simpson shares William's kind disposition, he dons glasses and a slightly messier hairdo most of the time.

Ben Barnes sometimes rocks a beardless face on the red carpets.
No — that's not Logan/Ben Barnes again. This is Hector Escaton — a bad boy host with a penchant for robbery and mischief.
Hector is played by Rodrigo Santoro, who may be scar-less but still carries the charm of his "Westworld" character.
Hector's right hand woman is Armistice — a badass host with a gnarly snake tattoo that stretches from head to toe.

Luke Hemsworth doesn't differ from his "Westworld" character much except for his classy black suit upgrade.
Another Delos employee is Elsie Hughes, who helps Bernard Lowe with programming and diagnostics.
She's played by Shannon Woodward, who wears her longer hair down instead of pulled back in Elsie's signature short ponytail.
Elsie's boss is Theresa Cullen — the Head of Quality Assurance. Some call her formidable, though Theresa knows that's just code for "b-tch."

Last but not least, Lee Sizemore is the Head of Narrative who loves pushing people's buttons.
Simon Quarterman didn't transform his looks much for the role, but we hope he's less antagonistic than his character.
