okay - this is kind of out in left field (but i've been rewatching season 2) and when john is about ready to let the counter count down and he and desmond seal themselves in the hatch and lock out eko and charlie, there's a scene right before desmond goes under the hatch to turn the failsafe key where he refers to locke as "Box man". Originally i assumed it was because locke was a regional manager for a box company, but now, with desmond having the forsight and of all the people on the whole island ben shows what came out of the "box" to Locke. Weird, right?
