The Scene: John Locke sees something in the wilderness, something that makes him stare in awe and wonder. He first describes it to Jack Shephard as “the eye of the Island,” and later described it as a “beautiful white light” to Eko in “Further Instructions.”
The Case for Jacob: This moment represents Jacob revealing himself in a fundamental way. Due to the unique nature of this encounter, Locke’s healed legs are the second part of Jacob’s healing process, with the first immediately after Locke’s fall from Cooper’s apartment. In this scenario, Locke was at one time important to the Island, but led astray by the Man in Black.
The Case for The Man in Black: What better way to start the mind tricks on John Locke than to fool Locke with a heavenly light, bolstering his new-found healed self? His nemesis might have cured Locke’s legs, but The Man in Black chooses to start working on Locke’s other wounded body part: his fragile, easily manipulated brain.
The Zap2it Opinion: John Locke might have died a patsy, but had the potential to live to be ruler. Rather than look at his character as one continual schmuck, perpetually duped and eternally insignificant, I choose to think his central role in The Man in Black’s plan demonstrated just how much he could have aided Jacob. As such, I look at this moment as Jacob’s Burning Bush, a message and a symbol of Locke’s importance that led The Man in Black to introduce an obstacle to lead John astray: The Hatch.
But that’s just my opinion, fans. What’s yours?
