Desmond:
We need to push the button.

Locke:
No, we don't!

Desmond:
Do you not hear me, brother? I crashed your bloody plane?

Locke:
How did you manage to do that?

Desmond:
On that day, those numbers turned to hieroglyphics. And when the last one came down this whole started to shake! And that screen? That screen filled up with "system failure," [pointing to the printout] System Failure! And I know what they are. 92204-September the 22nd, 2004, the day your planed crashed! It's real! It's all bloody real!! Now, push the damn button!!

Locke:
I know what I saw! It's a lie; it's not real! None of it is real!

Desmond:
You don't want to push the button? Then I will.

Locke:
No!

[Locke grabs the computer and smashes it on the floor. Desmond looks horrified. There's about 3 minutes on the timer.]

Desmond:
You killed us. You killed us all.

Locke:
No. I just saved us all.
