Lost, Season 6

Mother:
May I join you?

Man In Black:
[sheaths his dagger] Yes...how are you?

Mother:
I’m worried.

Man In Black:
Well, Mother, you should be. I spent 30 years searching for that place you brought me as a child--that...waterfall with that beautiful light. I’ve walked this island from end to end, not once coming close to finding it. But, then I began to think--what if the light underneath the island--what if I could get to it from someplace else? Figuring out how to reach it took a very long time.

Mother:
The people with you, they saw this, too?

Man In Black:
Yes, they have some very interesting ideas about what to do with it.

Mother:
Do with it? You don’t have any idea wh--

Man In Black:
I have no idea because you wouldn’t tell me, Mother!

[The Man In Black dislodges a stone, which allows light to filter in - Mother notices a large, wooden wheel leaning against the cavern wall]

Mother:
What is that?

Man In Black:
It’s a wheel...we're going to make an opening...one much bigger than this one; and, then I’m going to attach that wheel to a system we’re building. A system that channels the water and the light. And then I’m gonna turn it. And when I do...I’ll finally be able to leave this place.

Mother:
How do you know all this? How do you know it will work?

Man In Black:
I’m special...Mother.
