During an interview with former Lost star, Malcom David Kelley, who played Walt on the show, Kelley revealed that he will be appearing on tonight's episode, "The Life and Dead of Jeremy Bentham." So what did Kelley say about his role in tonight's epiosde?
TVGuide.com: But sure enough, Walt returns this week. In what capacity?
Kelley: Let's see.... I don't want to give anything away... but there's a situation where he knows something is going on, but nobody told him. It's that sort of thing.
TVGuide.com: What, does he get wind that Jack, Kate and the others are returning to the island?
Kelley: I'm just going to be talking to somebody, and.... Let's just say I know a little bit about what's going on, but nobody wants to tell me.
TVGuide.com: Now that the show is time-jumping around, do you get to play closer to your real age of 16? No more waving from windows or skewed camera angles?
Kelley: I do, and that's a very cool thing. I don't have to play this young boy anymore. I don't have to change my voice or have them dub in someone else's voice. There were a lot of things we had to do to try to make me sound younger.
