Niko: Now the sirens have a still more fatal weapon than their song, namely their silence. And though admittedly such a thing never happened, it is conceivable that someone might possibly have escaped from their singing; but from their silence certainly never.
Niko: Something is wrong.
Kelly: What is it?
Niko: Her sisters are coming for vengeance.
Kelly: I am not ready to die.
Niko: Living as a slave, like him, is a worse fate than death. Maybe we'll all die, but at least we'll kill all those monsters, one by one! Starting with you!
