Michael: Hey Locke…what's up with the blast doors?
Locke: Blast doors?
Michael: Yeah, Like in case of an explosion, they come from the ceiling. That guy down here, ah..
Michael: Yeah, Desmond…he didn't tell you what they were for?
Locke: No, no, he didn't. But he did leave a movie.
Micheal: A movie?
Locke: Yeah. You want to see it?
Mr Eko: (entering the room) I would like to see it too, if you don't mind.
Locke: Why not? The more the merrier.
