Kate: "Stop that!"
Subtext: "Stop being a dick."
Subtext: "I love being a dick."
Kate asks what's going on, and Jack explains that he didn't believe Claire's initial claims that she was being attacked -- the point being, of course, that now his guilt is driving him to find Claire. It's also all tied up with his guilt about the dead surgical patient, but don't worry if you don't quite get the connection; just bear in mind that Jack is frigging tortured, dude. Their convo is interrupted by a shout from the others; they've discovered that Charlie's left behind something to mark his trail: an elven brooch! Er, one of those dirty pieces of tape he wraps around his fingers!
Commercials. More scenes from this movie starring Dennis Quaid as Jack and Giovanni Ribisi as Locke, maybe, or -- God forbid -- Kate. Each scene makes me want to see the movie less than the last. Had they never advertised this film, they'd have had a better chance getting me through the door.
Back inna jungle, the trail has split. In one direction, Jack's found another elven brooch; in another, Locke has found footprints. Kate posits that Ethan might know they're after him and might be leaving a dummy trail. Oh, Kate, dear-heart: every trail you walk on is a dummy trail. Zing! "Now you're a tracker?" asks Boone, God's Friggin' Gift to Humanity. "You're just full of surprises," says Locke. Jack wants to split up; Locke thinks it's better to stay together. Jack overrules Locke, of course, and Jack and Kate head one direction, Locke and Boone, God's Friggin' Gift to Humanity the other.
