The End (2) - S6-E18
Question: OK, I am confused. I know the characters are really dead and they are in purgatory. But did they all really die in the plane crash and the events on the island was their purgatory or was their revealing that they were dead as a result of them dying on the island? If they did indeed die in the plane crash, where was Michael and Walt in the finale? If it was as a result of them dying on the island, then how did Kate, Hurley and Sawyer end up with the others in purgatory? I don't recall them dying on the island.
Chosen answer: No they did not all die in the plane crash. Everything that happened did happen... They all died... eventually. Their souls appear in 'purgatory' together and move on together. their 'lives' in purgatory was what they believed it to be. Time really has no meaning in 'purgatory', so they all appear to each other as remembered.
