Then again, it's not exhaustive either...Walter said:there were a few of those that were answered -- just not very well.
How did Eloise knew where Desmond would want to buy a ring for Penny, or that the guy with the red shoes would die?
What was up with the test Richard had young Locke pass? Was he assuming he would recognize the compass as being his? Why?
Why did Pierre Chang use aliases in the different Orientation videos?
Why did he have both arms in a 1980 video for the Pearl, explaining how the workers would have to observe what's going in the Swan station, when we've been told he lost an arm during the 1977 incident before the Swan station was even built?
Why did the DHARMA Initiative bother with the Pearl and Room 23? What did those have to do with the island and its strange properties/powers?
Why did the DHARMA Initiative let two guys handle the Swan station ever since the Purge if the fate of the world was at stake? Why didn't they ever come back?
What stopped Widmore from going back to the island if he had the address of Eloise's station right there on his desk?
What was the "loophole" that the Man in Black used to kill Jacob, and that he supposedly discovered sometime after trying to have Richard do the deed?
Who killed the other passengers of the Ajira flight?
etc.
