Was not Jack's addiction in a future which may not come to exist?


And I cannot come to think what it was that Locke lied about? I honestly thing Locke has a lot to do with uncovering the secrets of the island and we may have him speaking more with Jacob. Someone is out to get the island's secrets. And it appears that Desmond's girlfriend, Penny, may know - or her father may know of the island since his company's logo (Widmore Corp) has been on some items that were in the late hatch and Alvar Hanso was once on the board of the Widmore Group/Corp.
