Purgatory also doesn't explain the "mysteries" of the island, why Hurley was able to leave and come back, and the whole tracking of the "moving island" by groups outside of the island.
Doesn't explain some of the characters that weren't on the plane, the people already on the island, and that weren't back for the reunion at the end.
