↑ 1.01.1The Lone Wanderer: "What's your story?" Alex Dargon: "Who, me? Oh, nothing special. I grew up in Rivet City, and was always interested in what the scientists were doing there. Doctor Li took me under her wing, and taught me everything I know. Dan and I were out in the field when we got the call to come back." (Alex Dargon's dialogue)
↑Fallout 3 Official Game Guide Game of the Year Edition p.60: "Alex Dargon A specialist in growing naturally occurring foodstuffs, Alex is a well-liked, if a little over-eager scientist, and part of Doctor Li's trusted team. He is soon entrusted with overseeing elements of Project Purity, and is a little in awe of his mentor, Doctor Madison Li." (Fallout 3 Official Game Guide Game of the Year Edition Wasteland Census)
↑Alex Dargon: "Hey there. I hear we have you to thank for getting us up and running again!" The Lone Wanderer: "Do you think Project Purity will ever work again?" Alex Dargon: "I don't see why not. Between Doctor Li and your dad, we've got the best minds on the job. They can do just about anything. Yeah, I think we'll be up and running in no time." (Alex Dargon's dialogue)
↑The Lone Wanderer: "Where are the flood control pumps?" Alex Dargon: "You're kidding me, right? Ugh. They're downstairs in the sub-basement. You want me to hold your hand while you look for them?" (Alex Dargon's dialogue)
↑The Lone Wanderer: "Anything I should know about this place?" Alex Dargon: "I'd steer clear of the water if I were you. It's seeping in from the Tidal Basin, which means it's radioactive. If that's not bad enough, if there are any loose wires as the power comes back on... you might get a bit of a jolt. Know what I mean?" (Alex Dargon's dialogue)
↑The Lone Wanderer: "I have to go now." Alex Dargon: "Be careful, okay?" (Alex Dargon's dialogue)
↑Alex Dargon: "We'll make it out of here, right? I don't want to die down here." (Alex Dargon's dialogue)
↑Alex Dargon: "I don't want to die down here..." (Alex Dargon's dialogue)
↑Alex Dargon: "What is going on up there?" (Alex Dargon's dialogue)
↑Alex Dargon: "Thank God someone else made it out. What the hell is going on? Who are those guys? Did I hear gunshots?" The Lone Wanderer: "Can you help get us through this?" Alex Dargon: "What? You're supposed to be the tough one, right? Why don't you take care of it?" The Lone Wanderer: "I have to go now." Alex Dargon: "I really don't want to die down here." (Alex Dargon's dialogue)
↑Alex Dargon: "What the hell are we standing around for? If Garza can't make it, then we need to go without him. This is crazy!" (Alex Dargon's dialogue)
↑Alex Dargon: "Boy this place is something else, isn't it? Really amazing stuff here." The Lone Wanderer: "I have to go now." Alex Dargon: "Catch you around!" (Alex Dargon's dialogue)
↑The Lone Wanderer: "Where's Doctor Li?" Alex Dargon: "Oh. Well, she... After what happened to you when the purifier started, I think she just kind of had enough. It was really hard on her, you know? First losing your dad, and then the Enclave, and then the Brotherhood taking over here. It was really just too much for her. So I guess she packed up a few things and headed off north, towards the Commonwealth. Rumor has it there's a scientific community up there. I sure hope she finds what she's looking for." (Alex Dargon's dialogue)
↑The Lone Wanderer: "What are you doing here?" Alex Dargon: "Me? Well, I figured after all the work we already put into this place, we could help the Brotherhood keep things running smoothly. It's worked out pretty well so far, I think. They're not necessarily the friendliest bunch, but I've been doing what I can to get along with them." (Alex Dargon's dialogue)
