Locke’s escape a little more complex than it seems? *POTENTIAL SPOILER*
So I was watching the official Lost podcast not 5 minutes ago, and it was a behind the scenes episode with one of the executive producers, who was giving a tour of the set. At one point there lies a lot of props which have been used so far this season. Them and the Donkey Wheel. This leads to believe that they will use this at least once more this season. The most obvious thought brought to mind is that MIB would use it to grant himself a no-strings-attached escape from the island. But, if you remember back to mid-Season 5 when Christian appears and aids Locke, you’ll notice that he didn’t join Locke. My question: Why can’t MIB use the donkey wheel?
