What they’re saying

“This is probably something I should not tell you. I should have been a little bit more of a diva and I wasn't.”

— Fiona Dourif, Actress

“There's probably a quality of self-sufficiency that comes from going through hard things before you're a doctor or just losing the ground from under you. [The Pitt's creative team] wanted to show somebody who's been through a lot, had a lot of sad things happen, is resilient, and is doing her best. It's a privilege to be able to play it.”

— Fiona Dourif, Actress

“You don't have to do anything. All you have to do is be thinking the thoughts—and it's enough. It's like leaving yourself alone, you know?”

— Noah Wyle, Actor

“It's almost useful when you realize something like that. Our personalities are all just genetics and conditioning, right?”

— Fiona Dourif, Actress

“I've often been cast as—I would never say a villain—but people who are deeply lost and willing to do anything. That's sort of been my niche before McKay. It's been really lovely to play a good person. She's a good person who's been through a lot, but she's trying to do her best. There's something uplifting about that. That's the secret sauce to the show. People are desperate for a real portrayal of kindness.”

— Fiona Dourif, Actress
