- Will Halstead: Hey, Doc, I got a patient in 4, Brittany Coleman, stabbed her neighbor. Cops have her under guard. Seems pretty nutty. Wanna take a look?
- Daniel Charles: "Pretty nutty". Is that a... is that a clinical term?
- Will Halstead: She's had fentanyl, but no sedation.
- Daniel Charles: I'll be right there.
- Natalie Manning: So, your wife tells me that Ben hasn't had any of his childhood vaccinations.
- Aaron: Oh, god, here we go. Really? You had to tell her? You know how these people think, honey.
- Wendy: Yeah, I had to tell her.
- Aaron: If you notice, Doctor, our son is doing just fine.
- Natalie Manning: Yeah, maybe he's just fine, but your niece is in there with whooping cough, most likely because of him, because of you.
- Aaron: You don't know that.
- Natalie Manning: That baby is suffering horribly. She could die.
- Wendy: Aaron!
- Aaron: Look, I'm sorry, but I have to do what I think is right. I have to protect my son.
- Natalie Manning: Oh, you think you're protecting him? Do you have any idea how dangerous an ED is for a child without immunity? Do not assume that there aren't more idiots like you out there.
- Aaron: Excuse me?
- Natalie Manning: And who knows what these kids might have. Measles, mumps, polio. Get your son out of here.
- [he doesn't move]
- Natalie Manning: I'm serious. Get your son out of here now.
- Noah Sexton: How could I have missed that? I did a chest x-ray and an EKG...
- Connor Rhodes: Neither of which showed the aortic dissection. Look, every indication was that the guy was having a heart attack.
- Noah Sexton: What if I had just done a-a bedside echo?
- Connor Rhodes: Why? Look, you thought your priority was to get him to the cath lab.
- Noah Sexton: But that was wrong.
- Connor Rhodes: Look... we're all taught to see things a certain way, and most of the time, that works, just... not all the time. It is a very, very hard thing to see past our assumptions. Believe me, I'm still learning.
- Daniel Charles: I think we're dealing with a case of folie à deux.
- Will Halstead: Which is...
- Daniel Charles: A shared delusion.
- Jay Halstead: [approaching] Heads up, guys, I got an arrest warrant for Brittany Coleman, attempted murder. Gonna transfer her to the psych ward at Cook County.
- Daniel Charles: Before you do that, there's somebody I'd like you to meet. Two minutes.
- Jay Halstead: [sarcastic, after a veiled threat to Daniel] You sure know how to bring out the best in people.
- Daniel Charles: Yeah, it's a gift.
- Will Halstead: That guy who didn't immunize his kid, did I hear you call him an idiot? That was a very Will Halstead moment.
- Natalie Manning: I just... I can't stand it. No matter how much science we give people, no matter how much proof, they just go on believing what they wanna believe. I mean, the guy who started this whole anti-vac thing has been completely discredited. So what is wrong with people? Why do they keep clinging to this myth?
- Will Halstead: Mass hysteria.
- Natalie Manning: Yeah, and that baby pays the price.
- Ava Bekker: So, which of your myriad girlfriends gets Dr. Rhodes tonight?
- Connor Rhodes: [with a derisive laugh] Yeah, no. Tonight, it is just me and Jimmy Fallon. I've gotta... I gotta pace myself, you know?
- Ava Bekker: You're a real mystery. You used to be such a one-woman guy.
- Connor Rhodes: Yeah, well, that didn't work out particularly well, did it?
