[after the player either saves or harvests the first Little Sister in — BioShock 2

"Sofia and I knew that to create the first true Utopian would come at a high cost, my friend. We needed someone to be host to all that ADAM... Rapture’s finest minds. A willing subject. That is to say... Myself. [the lights turn on, a glimpse of a grotesque creature can be seen inside the tank as Alex the Great screams in pain] Whatever you may have seen inside the tank, that was indeed me. I fear the fate of Eleanor Lamb will be less physical, but no less grotesque. This tank for deep sea life is the ideal way to... to dispose of me. But first, you must retrieve enough ADAM-infused plant life to lure me out. The slugs feed on the stuff, and it’s... All I seem to want now. I have left a sample here so you know what to look for."

"Free will, Delta — Eleanors gift to you, and with each decision, you twisted her into your own image. Sinclair has no such choice — yet in its absence, he serves the world unerringly. He is now the better man."

"[If the player chooses to spare Grace Holloway] By sparing Grace, do you seek to gain my trust? A feeble ruse. Your crocodile tears may poison her with doubt, but I am not so easy a mark."

"Do you think me a Tyrant, Delta, vying for control of a dead mans dream? The city is nothing. Rapture must die, so that Eleanor may rise from its body. Allow me to demonstrate..."

"Citizens of Rapture, this is Subject Delta. Behind that mask hides an enemy of the People, without soul or sympathy. It is a beast apart, and as Family, we must tear off its jaw and drive it back into the sea."

"This is an emergency: Subject Delta has escaped; Eleanor Lamb has turned her back on her own People. Stand and fight, or the Rapture Family falls together."
