Ok, we know that the Oceanic 6 get off the island. We also know that as of three (?) years later, they are still off the island, but some of them (Jack and Hurley) are pretty dead set on returning.
So, its years later, and some or all of the Oceanic 6 make the return. What do they find?
Have the surviving lostaways joined forces with the Others?
Did the Others kill most of the lostaways (or vice versa)?
Did anybody attempt to rebuild/move into one or another of the remaining Dharma stations? (The Hydra station might not be too bad of a choice, and the Staff might work in a pinch for a few people).
Did the people on the island remain semi-civilized or regress into savagery?
Does Widmore or Hanso or somebody else have some people running around? (shipwrecked freighter folk, for example).
Take your best shot.
