History Headscratchers / Lost

So it's pretty well established that from Richard's perspective everyone related to the plot just vanished when the island was moved. They continued to spend three years living on the island in the relative present fighting with Claire (and presumably ghosting Ben's attempts to get back to them). So why? Why did Richard, Claire and Rob McElhenney not time travel? Or I guess, why did everyone else? It was probably a pretty equal sized group between those that time travelled and those that didn't, but not a randomly selected one. It can't be any inherent trait to the Others or how they came to the island or anything, as Juliet was just like any other Other until a few days ago. Maybe it's a case where only candidates time traveled. Only, Miles was part of the time traveling gang and there is absolutely nothing to indicate he is a candidate in Season 6. No one has any interest in him, and very little has changed about his life that would make him a living crossed out candidate like Kate (and even then, Jacob suggests being crossed out doesn't actually change a Candidate's Candidacy). Rose and Bernard also time travel and don't appear to be Candidates (and, in fact, would be rather good choices to protect the island as, while they've already found happiness in their lives, it's a happiness of solitude and remaining on the island). So we know the people who time travelled weren't selected based on being a candidate, their arrival on the island or their proximity (as John vanished right in front of them). There seems to be no reason at all why Richard and co didn't time travel, other than it would have made the plot way too messy to have the others interacting with themselves in a large group.

*** It could have also just been translated for our convience. In Across the Sea they start off talking in Latin but then just switch over to English mid-conversation.

[[folder:Who Faked the Crash, and Why]]
There's something I don't understand at all, and it only hit me while watching the series again in marathon style. Charles Widmore supposedly faked the crash of 815 to cover up the island's existence. Okay, so we're shown evidence that Widmore dug the bodies out of a cemetary to get corpses and bought a duplicate plane for the fake crash, and had it sunk in an ocean trench. But this evidence is shown us by Tom Friendly in the course of convincing Michael to go aboard the freighter as Ben's agent, and as with any of the Others he is almost always an UnreliableExpositor. Then again They have the weirdest habit of telling the truth unexpectedly. But we're also shown the black box supposedly from the crashed plane, and told Widmore paid a great deal to get it recovered. Now, if he planted the fake plane, why would he need to recover the black box? It wouldn't do him a damn bit of good. And why go to such lengths just to acquire a prop to show his employees? (And why would he need said prop in the first place?) On the other hand, it's possible Ben and the Others staged the whole thing; but in that case, why plant a fake that only draws attention to the plane again? Widmore is looking for the island ''anyway'', and it's supposed to be unfindable. Was it meant to throw Widmore off and make him go look for the island at a set of fake coordinates, hence the black box? There are internal contradictions no matter which theory we ascribe to. Unless I'm still missing something??
