↑ 1.01.11.21.3Cooper Howard: "Oh. Hello there. Yep, it's me, Cooper Howard, star of stage and screen. But I'm not here today to talk to you about my latest picture. No, today I'm here to show you a vast and wonderful place, not made by God Almighty but by the working man. A veritable Camelot of the nuclear age. Now, how 'bout we turn on some lights. There, that's better. Now, I'm speaking to you from deep inside the fully-livable Model 96JQ1164. And what a beaut she is. And what a song she sings. Now, that right there is Vault 4's three-foot-thick lead casing. Strong enough to keep out the rads and the Reds. Each one of these underground burghs comes with all the modern amenities you've come to expect from our rip-roarin' republic. Now, this corridor here is Sycamore Street, where you'll wave howdy to any one of your 200 neighbors on your way home for an enchanted evening with your loved ones. Mm. Meet the Hawthornes. Now, this isn't just your average all-American family. No, Lloyd and Cassandra here are both scientists, specializing in the effects of radiation on human DNA." Lloyd Hawthorne: "That's right. And we'll be living and working right here in Vault 4, leading a community governed entirely by scientists." Cooper Howard: "Wait a second, did you say "living down here"? Well, there hasn't been a nuclear incident, has there?" Lloyd Hawthorne: "Uh, no, not yet. But, uh, our family and a group of 80 volunteers will be conducting a five-year trial of Vault 4. To demonstrate to the world that, no matter what comes our way, America will be ready." Cooper Howard: "Five years. Well, I may play a hero in the movies, but... you all are heroes in real life. And now you can be a hero, too. By purchasing a residence in a Vault-Tec vault today. Because if the worst should happen tomorrow, the world is gonna need Americans just like you to build a better day after." ("The Trap")
↑ 2.02.12.2Overseer Benjamin: "Sorry, I haven't, uh, seen that footage in a long time. But it's a stirring reminder of what this place is all about." Lucy MacLean: "I-I don't understand, I... In the lab, I-I saw your doctors..." Birdie: "Trying to ease the pain of the poor souls your people lured into this place. His ancestors were used as lab rats by the original residents of Vault 4. Until the lab rats rebelled." Benjamin: "The, uh, creature in the video was actually my Great-Uncle Peter on my mom's side." Lucy MacLean: "I'm so sorry. I... I had no idea the original vault dwellers here were so... so weird. I mean, my vault's not like this." Benjamin: "What was the experiment in 33?" Lucy MacLean: "W-Well, there is no experiment." Birdie: "Your ignorance cannot excuse your cruelty. You have infected our home with violence and now you must pay the price." Lucy MacLean: "No! Please. Please, I'm a good person." Note: Birdie calls the test subjects "poor souls your people lured into this place," with "your people" referring to the original Vault dwellers. ("The Radio")
↑Lloyd Hawthorne: "Overseer Hawthorne, final log entry. At this point, it would be irrational of me not to acknowledge that these may be my last words. But despite our results here, I want to reiterate that a society governed by scientists--" Cassandra Hawthorne: "Honey! Hey!" Lloyd Hawthorne: "--really is the ideal social structure. What happened here should not be used as a case study for what happens when scientists are given unregulated control." Cassandra Hawthorne: "Lloyd, gimme a little help! --" Lloyd Hawthorne: "And-and... and-and hybridizing humans with radioactive-resistant species still has potential. Our test subjects were less compliant than we expected. Cassandra! Oh, no! No, no, no! No!" ("The Radio")
↑Lucy MacLean: "We can't thank you enough for letting us in and taking care of us." Birdie: "It's what we do here. Oh, and we found his armor. Our surface foragers are bringing it back now." ("The Trap")
↑ 5.05.1Benjamin: "But hey, that's something. You don't meet a natural-born vault dweller every day. We're a dying breed." Lucy MacLean: "Oh, you're... you're from here?" Benjamin: "Five generations, and proud of it." Lucy MacLean: "Ah. I just thought because... Because so many, uh, people here seem to be refugees from the surface." Benjamin: "Tell me about it. Ooh. These people. Am I right? I grabbed a moldy one." Lucy MacLean: "What do you mean by that?" Benjamin: "Well, you won't find anyone more open-minded than me, but they come in here with their smelly food and their weird ideas. You're from a vault. You get it." Lucy MacLean: "I-I don't understand. If you don't like people from the surface then why do you keep taking them in?" Benjamin: "It's a policy from before my time. But these newcomers, ooh, let me tell you, if you want to get elected, you have to respect their traditions and tolerate them and not call them "surfies." It's awful. What, you don't take in surface dwellers in your vault?" Lucy MacLean: "Well, to be honest, no, we don't." Benjamin: "What is that like?" Lucy MacLean: "No, I think what you're doing here is a really good thing. I saw what was left of Shady Sands. An entire city just destroyed in an instant. It... I mean, some of these people lost everything." Benjamin: "And that was a tragedy. So we took our share of them in and gave them a home because it's what we do. But it's like you can't make a funny joke about it without offending these guys. I mean, one funny joke I told on maybe ten occasions." Lucy MacLean: "What was the joke?" Benjamin: "I forget. All I know is it was a huge bomb. Pretty good, right?" ("The Trap")
↑Birdie: "I was born on the surface." Lucy MacLean: "Oh. Uh, sorry. I-I didn't know. You seem so..." Birdie: "Normal? My mother was a courier. I was 11 and traveled with her to Filly. Three days' walk from home and we could still feel the heat from the blast." Lucy MacLean: "You're from Shady Sands." Birdie: "Many of us are. We were lucky to find such a hospitable community here in Vault 4." ("The Trap")
↑Lucy MacLean: "Oh, uh, excuse me? What's going on?" Nurse Powell: "It's a Surface Dweller tradition. It can get a little rambunctious for my taste. You're welcome to come." Lucy MacLean: "Sure." "(The Trap")
↑Chant: "Flame Mother, we remember. We bring back the past as we remember. We bring back Shady Sands... ...as we remember. We bring back those taken from us by covering ourselves in their ashes. To bring back Shady Sands, blood must spill. Oh, Flame Mother, you will be our salvation." ("The Trap")
