The Joker: "Would you die for me?"
Harley Quinn: "Yes."
The Joker: "No, no, no. That's too easy... Would you live for me?"
Harley Quinn: "Yes."
The Joker: "Careful. Do not say this oath thoughtlessly! Desire becomes surrender. Surrender becomes power. You want this?"
Harley Quinn: "I do."
The Joker: "Say it. Say it. Say it! Pretty pretty pretty pretty..."
Harley Quinn: "Please?"
The Joker: "God, you're so good."
