Arrow, Season 2

Blood:
As a young boy, I was plagued by nightmares. Every night, I would wake up in a cold sweat, frightened and alone. It was my father's face that haunted me. [Shows his mask] And this is how I saw him. The embodiment of desperation and despair. I made this mask to conquer my fears. And to remind myself why I fight, every day, to give this city's most desperate a chance. All I ever wanted to do was help people, Oliver.

Oliver:
Help me believe. Where's the cure?

Blood:
Slade Wilson will not rest until he honors the promise that he made you.

Oliver:
I won't be so easy to kill once we level the playing field.

Blood:
He's not interested in killing you. Not until he's taken away everything and everyone you love.

Oliver:
After he murdered my mother, he said one more person had to die.

Blood:
Whoever you love the most.
