Lost - "The End" Spoiler

Some crew member of Lost left a call sheet in a Honolulu restaurant last night and some spoilers have been revealed!
Defamer says ABC confirmed that the document they found was authentic. Also: leaving spoilerish documents/iPhones seems to be the new trend -- I need to go out more and find these!
From Defamer:
Well, it mentions skeleton props. Which, to us, means the Adam & Eve skeletons from wayyy back in season one.There is also a lot of language about people being lowered on ropes into waterfalls or something. The boys (there are no girl characters listed on the sheet) are off on some sort of rope-climbing adventure involving water and light. Water and light that Jack is "consumed" by.
Jack gets a nosebleed. Like a time sickness nosebleed? MYSTERY.
Most importantly, what does it mean when it says "Jack in Hell"?? That's capital-H Hell. That's real Hell. Are we going to Hell on Lost? We just might be.
Can I revisit my the "Lost island is purgatory" theory a few years ago? Hell??? White light??? Is this some kind of angels vs. devils thing?
