And Found: Lost – “The Substitute” (6.04)

Our island friends are all out of sorts on this episode of Lost. As we follow Locke in his alternate, plane-safely-landed universe we see a much different man than the boar-hunting Locke we once knew. Still living with the love of his life Helen, Locke struggles to keep his faith—and he’s usually faith’s biggest advocate—while coming to grips with the reality of his handicap.
Meanwhile, on the present-day island, Locke’s body is up to no good. Inhabited by the man in black a.k.a. the smoke monster a.k.a Jacob’s arch nemesis, people are scared of this guy. Everyone who’s not already at the temple wants to get there lickity-split. Especially Richard, who after being beaten and strung up in the jungle is as jumpy and frightened as a lost kitten.
Sawyer’s the only one who’ll listen to the man in black/Locke, even against Richard’s advice. Sitting in his Dharmaville house, drowning his Juliet’s dead sorrows in some alcohol, Sawyer’s got nothing to lose. And even through his whiskey haze he can tell something’s up. He knows this new Locke has changed; he’s not like the old Locke who was afraid. Astute observation, Sawyer. But after Locke promises to show him why he’s on the island, Sawyer goes for it. He says, “Well, I guess I better put some pants on,” and the pair embarks on a cross-island journey to a cave carved into the side of a cliff.
While trudging through the jungle, smoke monster Locke sees a young blonde boy dressed in typical Others tattered garb. The second time this mystery boy appears, Locke chases after him, and the boy admonishes him for killing Jacob, reminding him that, uh, that’s not in the rule book. Non Locke, mirroring the real-life Locke, screams, “Don’t tell me what I can’t do!” And you’re just waiting for him to follow that sentence up with a qualifier: “Don’t tell me what I can’t do, Aaron!” or “Don’t tell me what I can’t do (fill in blank)!” But, it’s quite possible that this blonde jungle-dweller could be crazy jungle Claire’s son Aaron, who’s fate is as tied to the island as any of the Oceanic passengers.
