Matthew Fox played two guys in Lost season four: the confident, take-charge Jack on the island, and the haunted, addicted Jack in the future. We got a chance to talk to Fox one-on-one about how he went back and forth between those two Jacks. And also how he's going to play a more "spiritual" Jack in season five. We also talked about the complex relationship between Jack and Locke. Click through for part two of our interview video.
