Danik: This isn't the way, Isaac! There is a future for you! For all of us!
Isaac: Leave me alone, Danik.
Danik: You can see them again, Isaac. Everyone you've lost along the way! It's a future with no regrets!
Isaac: I have no regrets, Danik. One way or another, this will all be over soon.
Isaac: Oh no you don't!
Danik: I know you think you're doing the right thing, but you are wrong, Isaac! You have to let me turn off the Machine! My reinforcements have arrived...with a big surprise.
Ellie: Isaac? Isaac!!
Isaac: You're alive? But how did you...
Ellie: I escaped through the delivery tubes, but they caught me! Isaac, they're going to cut you off at the...ahh! Let go of me!
Danik: Shut up, heretic!
Isaac: I have the Codex, Danik! If you want it, you'll have to find me!
Danik: No, I won't. You're heading to the Machine. And when you get there, I'll be waiting.
Male 2: Move! Move! Move!
Male 3: He's here!
Male 4: Take cover!
Isaac: Okay, now what? Three receptacles..three statues...three markings What's this final step?
Male 5: Get him!
Male 6: Get this one!
Male 7: Pull back!
Isaac: All right, Carver, another door just opened up. We've got to be close to the control center for the Codex, we've done everything else Serrano said to do! I'm heading in!
Male: Well, I've gone and busted my knee open. I suppose the Codex is in Mahad's hands by now, and this place is about to be buried, like everywhere else. I remember telling my college professor I wanted to study xenoarcheology. He laughed right in my face. There's nothing to study, he said. It's all dead space. No alien life exists out in the universe. In a way, I guess he was right. There is no life beyond our system, only a trail of extinction, wrought by the Moons. And now it's right on our doorstep.
Well, above us lies the means of turning off the Machine, but also the means to complete it. Turning it off will finish our species, completing it will save us. I had hoped to be here to witness the saving part. It would have been spectacular to witness the Moon getting pulled into the planet and crushed to oblivion--a final act by the natives--a sacrifice to save us all. But now, I must rest. Perhaps Tim will be along soon with the Codex.
Ellie: Isaac! Don't do it! Don't listen to him!
Danik: Give me the Codex, and you can have her back.
Ellie: No! Isaac, you know what's at stake!
Isaac: Okay, everybody calm down, okay? Danik...
Danik: Give me the Codex...or I will kill her!
Carver: Isaac, what are you doing? You've got a second chance!
Isaac: If he turns off the Machine, we're all dead--her, us, everyone!
Carver: Don't let it all go dark, Isaac. There's more than one kind of right.
Danik: I've done it! I've finally done it! The darkness is at an end! Let the evolution begin!
Isaac: Ellie, when I finish this, it's all going down. Everything. You have to go.
Carver: No! You two get out of here. Go back to Earth Space. Tell 'em what we found! I'm staying! It's all I got left.
Isaac: You can't stop it, Carver! Not without me. I'm the Marker Killer, remember?
Isaac: I turned my back on the world because I was afraid of what needed to be done. Ellie, I'm not afraid any more. There's a shuttle over there. I want you to take it and head for home. Don't come back for me! We both know I'm not going home. Go!
Carver: Oh shit! Damn! This whole thing's coming apart behind us!
