"So you people are just whatever's left over of them." Juliet says Dharma was a long time ago: "It doesn't matter who we were. It only matters who we are. We know exactly who you are, Jack Shephard," she says, opening her file. And yeah, this show really ought to consider exploring themes of identity, and how who we were informs who we are, and how the island is a chance to make a fresh start and all of that. They really ought to give that a shot.
"You don't know anything about me," says Jack. Oh no? "We know that you're a spinal surgeon based out of St. Sebastian's Hospital in Los Angeles. I know that you went to Columbia and that you graduated med school a year faster than anyone else. I know that you married only once ["only"?] and that you contested the divorce. I know your father died in Sydney. I know this because I have a copy of his autopsy report." Jack looks stunned by this. He asks how they got the autopsy report, and all Juliet says is, "We got it." Not like they're going to share their methods with the Lostaways, but I'm sure we'll get a real explanation later as to how they've come by this kind of documentation, right? So he asks about the massive file she has on him. "This, Jack, is your life." Jack wants to know if the file is just about him or if it's about his family and friends, too. "It's pretty much about everything," says Juliet, and Jack needs to be told that "everything" includes his ex-wife. "What would you like to find out?" she asks.
Flashback to Jack sitting in a jail cell, at least until the guard strolls over and says someone posted his bail.
Leaving the booking area, Jack's putting his wedding ring back on, and he sees Sarah standing there waiting for him, or at least waiting to make sure Jack knows that she was the one who bailed him out, because as soon as she tells him that his dad told her he was there, and that she called him a cab, she spins on her heel and leaves.
He follows her out of the station, which means he gets to spot the man waiting for her, who isn't waiting in the car like a normal person would, but standing there leaning on the car. So now we get to watch another soap-opera argument about who this guy is and why it matters and blah blah blah blah, and this is certainly more interesting than checking in on Locke, or Eko, or Hurley, or Claire, or Desmond, or even freakin' Charlie, isn't it? Sarah gives him a lecture about how Jack's dad called her to help, and that he was so drunk he could hardly understand him. "Look at the bright side. Now you have something to fix," she says, and stomps away without telling Jack what this guy's name is.
