Carlton Cuse: Is there still electromagnetism on the Island? I would say yes there is. Is there electromagnetism that is going to lead to an imploding black hole and the end of civilization as we know it? Perhaps not.
Damon Lindelof: Lets just say like theoretically inside the Island there was this ball of electromagnetic energy. And lets just say there was a group of people – we’ll call them the DHARMA Initiative sort of drilling around and and doing general futzing on the Island and they accidentally drilled into this hole and suddenly that entire ball of electromagnetism became untapped so that they built this Swan station above it in in an effort so that it wouldn’t get completely out of control. So that by plugging that hole you don’t actually do away with all the electromagnetism. Its still there.
Carlton Cuse: It became tapped actually.
Damon Lindelof: Yes. Tapped. that’s right.
Carlton Cuse: Not untapped but then now its been re-corked. Lets just call it corked. Its been corked. Its not its its fine. Don’t worry about it.
Damon Lindelof: Its tapped
Carlton Cuse: Don’t worry about it right now. You’re ok.
Damon Lindelof: I’ve had so much beer in my life that I should know what tapped and untapped is.
Carlton Cuse: Especially before this.[/Spoiler]
