Zoey BarkowPlayed by: Merritt Wever
Zoey Barkow is a first-year nursing student. She's impressionable, exuberant and talkative; the opposite of Jackie.
Zoey's enthusiasm for her job has yet to be crushed by the grind of patients and a flawed healthcare system, though even Jackie appreciates how excited she gets over the smallest procedures.
Near the end of the pilot episode, Zoey actually refers to Jackie as a "saint."
