Island; 1977: The hatchback is open again. Maybe they decided to air out the death stank, after all. Hurley grabs a sandwich and tries to get Miles to talk about how his dad is "the dude from all those movies. Only back then, he was called 'Marvin Candle'. Was that like a stage name?" Miles says, "What part of 'I don't want to talk about it' isn't sinking in?" Hurley says that if Miles hadn't wanted to talk about it, he never would have told him that Chang was his father. POINT! When Hurley asks how long he's known, Miles says, "The third day we were here, I was on line at the cafeteria, and my mother got in line behind me. That was my first clue." I can see how her face might ring a bell.
Hurley reminds (or informs, I can never remember who knows) Miles of the Dharma Initiative purge. He asks him if he wants to save his old man. Miles reminds him that they're going to be killed regardless of anything he does. "So why bother?" Chang comes back and orders Miles to take him to Radzinsky at "the worksite." He then cautions Hurley not to say a word. Hurley doesn't need to hear the end of the threat. "Polar bear poop. Got it." As Chang gets into the passenger seat, Miles asks him what happened to the body. Chang turns around and deadpans, "What body?" Heh. Thank goodness Hurley doesn't explain which one Miles meant.
Dharmaville Schoolhouse: Jack erases the right-hand third of the blackboard (and the indispensable Lostpedia has a summary and analysis of its contents, here) when Roger walks in and demands to know why Jack is working a site that's on his "rounds." Jack calmly explains that he heard what happened to his son and thought he'd cover for him. Roger asks which part Jack heard: "That he got shot or that someone kidnapped him from the infirmary?" Jack, who has the middle section of the board all clear now, has been on Lost a long time, Roger. He's not going to answer a question directly. "Then what are you doing here at work?" See.
Roger says, "What else am I gonna do? Sit around and pray that those idiots are gonna find my boy?" Sheesh, Roj, it might not hurt. Or, you know, if you're a science-only dude, you could sober your ass up and look for the kid, yourself. Jack's an old-pro at dealing with drunken daddy issues, so he wisely turns his back on Roger and gets back to work on the left-hand side of the blackboard. This pisses Roger off, so he tells Jack he can "Get out of here," and then kicks the mop bucket, for emphasis. It's on wheels, so it rolls across the classroom and bangs into a side door, knocking it ajar.
