Someone said on Lost-streams.com that the guy Jacob was speaking to at the start of the episode is the guy who has been pretending to be John Locke (seeing as they found Locke's body in the plane's hold). Don't know if this is correct or not. Could Locke not be something similar to the "dead people visions" some of the island inhabitants have had but that everyone on the island can see him?
Anyways, a lot of questions answered but a lot of new ones created. Got to wait another bloody year now
