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."
Zoey: I can't believe she took the money!
Jackie: Yeah, but bullshit like that comes in all the time, clogs up the waiting room, slows everybody down. Wasn't even my 20, I got it off a dead guy in the morgue. (Zoey looks at her) Just kidding, Zoey, just kidding.
Zoey: I'm not sure that I can do this. I mean I... You and Mo-mo, you're all so good at what you do. And the doctors... Oh my God! They're healers. And this place is so amazing. I got into nursing because I wanna help people, and I'm afraid I'm just slowing you down.
Jackie: What's this about? Nobody ate your muffins? You found an ear in the toilet? So what? You know what this job is honey? This job is wading through a shit storm of people who come into this place on the very worst day of their lives. Just so you know, doctors are here to diagnose, not heal. We heal. All saints is in the business of flipping beds. That's it. End of story. The fact that you have even the slightest inclination to help people puts you miles ahead of 100 percent of the population. So stop crying, okay? Buck up. If you need to cry, go do it in the ladies' room. Is that clear?
