Riva Ridge

Live Together Die Alone:> Biggest Reveal - The world still exists outside of the island
> Desmond's boat - "The Elizabeth" named after Libby by her late husband, David
> Fake Henry obviously pushed the button, but why try and convince Locke otherwise?
> How does Des know the "hostiles." Has he had a run-in before?
> There appeared to be at least 100 letters from Des to Penny in the box Widmore had. If Desmond wrote 1 letter a week, that's roughly two years in prison.
> The Incident - there was a leak and now the charge builds up & the button needs to be pushed in order to discharge it before it gets too big
> Whispers - "Elizabeth"
> High-Tech Stun Darts - Zeke & Company are still connected to outside world to have such state of the art weapons
> "You've killed us. You've killed us all". -Desmond
"No, I just saved us all". -Locke
Is this an allusion to Penelope being able to pinpoint the Island's location as a result of the magnetic pulse?
> Fake Henry tells Michael to follow the compass bearing, 325, or NNW. Is this the way out from the island? Or, if he travels in this direction will he reach the ferry mentioned in the Pearl Orientation video?
Or, maybe it's just a reference to one of J.J. Abram's favorite movies, "North by Northwest".
