"Ah! At last, a signal! You, who are bringing this dead city to life, listen. My name, it is Tenenbaum. I know who you are. And I am in much need of your help. Please, find me in the Atlantic Express train station."

"[into and out of static] Hello? Hello — can you hear me? Your-your signal, it is very faint... [back into static]"

"[if the player rescues all of the Little Sisters] The Rapture dream is over, but in waking I am reborn. This world is not ready for me, yet here I am. It would be so easy to misjudge them. You are my conscience Father, and I need you to guide me. You will always be with me now, Father, your memories, your drives. And when I need you, you'll be there on my shoulder whispering. If Utopia is not a place, but a people, then we must choose carefully; for the world is about to change — and in our story, Rapture was just the beginning."

"[if the player harvested at least one Little Sister] You made a monster of me, Father, but I wondered why you saved the others. You left me in doubt. Didn't you want me to be like you? I knew I could save you; but if you felt regret, if you wanted me to choose for myself I would have to let you go, to let you die."

"[If the player harvested all the Little Sisters] The Rapture dream is over, and in waking I am reborn. You may not have wanted me Father, but you defined me. You chose to survive, no matter the cost, and I will not let your instincts go to waste. You'll always be with me father, your memories, your drives; when I need you, you'll be there whispering from my shoulder. There is no name for what I am, but the world is about to change. And with your help, they will never see me coming."

"And then Father, the Rapture dream was over."

"...We... We've done it, Father — we're launching! Get to the elevator!"

"Look, Father, I know you may not have wanted a daughter. But love is just a chemical. We give it meaning by choice."

"I was afraid of this. Mother has bombed out the ballast compressors, Father. The lifeboat will be too heavy to launch. Unless... Let me think..."

"[after Lamb "pleads" with Eleanor to come back to her] Ah, yes... Mother's testing me. One last game. Fortunately, by now I'm the world's foremost expert at breaking her rules... I've made my choice, Father... and if needs be — I'll die for it."

"This is Sinclair's lifeboat, out the window here. It's our only chance of escape. From what I know of Sinclair, he wouldn't just abandon it..."

"Oh god! She's going to drop this building into the trench... It's miles deep! We have to find Sinclair!"

"Mother was right about one thing. I have been watching you, Father, studying the way you have treated others. And now I know who I am..."

"The other Sisters are made from me, in part. As they grow up in Rapture, I feel it all. When you were with the little ones, they trusted you as their father, because of me."

"[while the player is possessing a Little Sister and viewing the world through their brainwashed vision] Ten years, Father, stuck in this... This fever dream. Mother kept me sedated in order to "perfect" my mind with ADAM. To her, the ideal child is a genius, serving the common good without questioning it. You have saved me from that."

"What Mother did to me left me very weak, or I would do this part myself. To save your life, I'm going to have to change... To be like you. From here, you should be able to locate the pieces of a Big Sister suit... Please, bring them to me."

"Father... it's me, Eleanor. I'm so sorry... Mother stopped my heart, long enough to sever our bond. Staying near me won't stop you from dying now... Or worse... [a Little Sister clambers out of a vent] But I can still help you escape! This Little Sister's brought you something that will allow you to take control of her. [the Little Sister presses a finger to her lips, then uses her syringe on Delta. The player suddenly sees through the Little Sister’s point of view] I know this feels a bit strange, Father, but now you can see through her eyes and tell her where to go. This is how I brought you back without Mother catching on. Now... first, let's get you out of here."

"[Delta experiences flashbacks to when he was turned into a Big Daddy] This is where they bound us together, Father... Playing God... You were the only good thing that Rapture ever gave me..."

"Mother’s not lying this time, Father... He really did it... To both of us."

"[after saving or harvesting the last Little Sister in Dionysus Park] With me gone, Father... Stanley just let Mother’s followers turn into animals. When word came that she was returning, he knew they would blame him — so he found a way to silence them all... And now, he’s trying to cover it up..."

"[after saving or harvesting the second Little Sister in Dionysus Park] That’s me, there... I confronted Stanley — said I’d tell Mother what he’d done. He panicked — took me away and sold me to an orphanage. I tried to fight back... I remember biting his hand, but... Father... He’s the reason I was turned into a Little Sister.."

"[after the player either saves or harvests the first Little Sister in Dionysus Park] Father, this ADAM you’ve found contains memories from all of the bodies here. Normally, only a Little Sister can see them... But I can show you what Stanley’s trying to hide... When Mother was taken away, Stanley was left in charge of Dionysus Park... He spent all her money, threw these mad parties — it was like he was trying to ruin her..."

"[when the player finds the Launcher] Take this, Father, and hurry.. Mother can’t hear this but she’s... She’s looking right at me. And her face..."

"Come now, into the vessel. Our work together is only beginning."

"The Thinker never gave up on you, Mr. Porter. It could not leave you behind. Please, step up to the console and begin the bathysphere launch sequence. We have much work ahead of us."

"You see now why I let the machine speak for you, Mr. Porter. We needed a voice that would be familiar... Comforting. Your own. With that copy of The Thinker's programming, we may return to the surface... And use it to restore you to the man you once were. Please, collect the print-out and meet me at the bathysphere dock. Take your time, Mr. Porter. I'll be waiting."

"[after defeating Wahl] Quickly, take the Administrator Punchcard from Wahl's body and reactivate The Thinker!"

"H... Herr Sigma! It is Dr. Tenenbaum! With the computer disabled, Minerva's Den is falling to pieces! No pressure regulation, no air supply! You must defeat Wahl and bring The Thinker back to full power."

"Mainframe reactivated. Confirming user's genetic identity. Genetic identity confirmed: Alpha Series Subject Sigma. Former identity: Charles... Milton... Porter. [in Porter’s voice] Welcome back, Milton. [abruptly changes to the Thinker’s voice] Ending personality duplication. Subject: Charles Milton Porter."

"Your moment has come, old friend! I stand before you, the trusted partner who put a knife in your back. Do not disappoint me!"

"Porter! You have forced my hand! You see?! The Thinker is shut down! That leaves only two variables: You, and me. The equation... Ends... Here!"

"I've tried to keep you from the heart of the machine! You did not listen! When the pangs of familiarity sting you, my friend... You will have only yourself to blame."

"Ryan's secret police came for Porter, long ago. And now he has... Reappeared in Minerva's Den? A man sent to Persephone does not just open his cell door and walk home..."

"Is it your deep love for Porter and for Tenenbaum? Huh! You hardly know them, Sigma! You have never... even... Met them!"

"What is driving you into the Core, Sigma? What COMPELS you to defy The Thinker's equation?"

"The equation is nearing its conclusion, Sigma. The answers... Lie in the Core! The Thinker is waiting for you, Sigma! And so am I..."

"Porter worries you with Sofia Lamb's torpedoes? Hah! He fills your head with foolish visions of freedom. I can provide you more immediate concerns."

"I read to you now from the machine's prediction. "Sigma enters Minerva's Den. Encounters hostility." "Sigma enters Wahl's chambers." You see? The Thinker has chosen me! It does not care what I once did!"
