As they lean against the car and brush more dirt off, we see that it's a New Kids on the Block lunchbox. And of all the logic-defying aspects of this show that we're expected to swallow, there are some things some viewers just refuse to believe, and one of those things is, apparently, that a lunchbox from the '80s could have been out of metal instead of plastic. Anyway, inside is a red baseball cap that makes both of them say "wow," like I guess baseball caps don't exist anymore. Also inside? Tom's plane, which he says he can't believe he let Kate talk him into burying, but she says it was his idea. He flies the plane around with his hand a little bit, like WE SEE THE DAMN PLANE ALREADY, WE KNOW TOM SOMEHOW WINDS UP DEAD, LET'S MOVE ON. There's an audio cassette in there, and Kate says, "Kate and Tom, 1989." If you guys see my Martika tape, pass it along, 'kay?
So they sit in the car and listen to the tape (which was recorded August fifteenth, or 8-15, in another appearance of that number). Young Kate Austin mocks young Tom Brennan for putting his "stupid" plane in the time capsule, and Tom defends his plane by explaining that he got it when he got to go to Boston by himself. And young Kate sarcastically says, "Oooh, that is cool, just like this time capsule!" like nice portrait of the con artist as a young bitch here, and apparently Kate has always been this way. Young Tom says it'll be cool to dig up the time capsule 20 years from now. Young Kate wants to know how he knows they'll still be together. "'Cause we'll be married. You'll be a mom, and we'll have nine kids," which is certainly what boys young Tom's age spend all their time thinking about, and young Kate laughs and says she doesn't think so, and says that when she gets her license they should just get a car and run away. "You always want to run away," says young Tom, and young Kate reminds him he knows why, and young Tom says yeah. Meanwhile, the flashback Kate and Tom no longer seem to be enjoying the incredibly depressing time capsule tape with its implications of hurt and pain and possible molestation lingering beneath the surface. "Funny how things turn out," says Tom, and Kate agrees, although neither seem to find things super-hilarious. They look at each other, and then lean in for the inevitable tonsil hockey, which is even more tender than the time Kate kissed Sawyer. They break, neither of them looking particularly proud of what they've just done. Kate apologizes, and Tom just says that they should get to the hospital. Kate agrees, and they drive off.
Locke's in the jungle, scraping out a coconut to make some sort of paste that he's slathering on his leg wound, and Walt strolls up and asks him what he's doing, and Locke explains, and it all sounds very small-talky, and Locke just outright asks if there's something Walt wants to tell him. "I didn't do it," says Walt. "Didn't do what?" says Locke. Walt says he heard that Jack thinks someone made his dad sick, but he didn't do it. Locke contrivedly asks if Walt thought that because Locke knows Walt set fire to the first raft, that he thinks Walt's the one who poisoned his dad. Have to admit, the thought crossed my mind. Locke, squatting in front of Walt, explains that they're friends, and Locke didn't tell on Walt before and he's not going to tell on him now. Taking Walt's wrist, Locke says he knows Walt wouldn't do anything to hurt his dad. Walt seems visibly frightened by Locke's touch, but not really in a "Bad touch! Tell an adult!" kind of way. He shakes his arm free and Locke asks what the matter is. "Don't open it! Don't open it, Mr. Locke! Don't open that thing!" says Walt. "What thing?" asks Locke. "Just don't open it!" says Walt, who runs away. Locke glares after him, like, damn, how many people did Sayid tell anyway?
