Lost, Season Six

[Mother has brought Jacob to the cave of light]

Mother:
Do you recognize this place?

Jacob:
Yes,

Mother:
Do you remember what I showed you here?

Jacob:
The light.

Mother:
You're going to protect it now.

Jacob:
What's down there?

Mother:
Life. Death. Rebirth. It's the source. The Heart of the Island. Just promise me that no matter what you do, you won't ever go down there.

Jacob:
Would I die?

Mother:
It would be worse than dying, Jacob. Much worse. [She pulls out a jug of wine and pours some into a cup. She whispers a Latin incantation over it] Here, drink this.

Jacob:
What happens if I do?

Mother:
You will accept the responsibility that you will protect this place for as long as you can. And then you'll have to find your replacement.

Jacob:
I don't want to protect this place.

Mother:
Someone has to.

Jacob:
I don't care.

Mother:
My time is over.

Jacob:
Why, why is your time over?

Mother:
It has to be you, Jacob!

Jacob:
No it doesn't, you wanted it to be him [The Man in Black]! But now I'm all you have.

Mother:
It was always supposed to be you, Jacob. I see that now. And one day you'll see it too. But until then, you don't really have a choice. Now please, take the cup and drink.

[Jacob drinks from the cup]

Mother:
Now you and I are the same.
