Sayid: Naomi's boat is only eighty miles offshore. I know if we eliminate Danielle's signal they'll hear us.
Juliet: No they won't.
Sayid: And why is that?
Juliet: We're jamming it.
Juliet: Ben is using one of the Dharma stations to block all of the signals off the island except for ours.
Sayid: What station?
Juliet: They call it the Looking Glass.
Sayid: The Looking Glass?
Juliet: Yes, but it's underwater. I have no idea where it is.
Sayid: I believe I do.
