A few people are saying the island is moving backwards in time.
It had me wondering if the whole time thing is related to some of
the healing we have seen. Mainly with John, Jin and Rose.
If time is moving backwards, could the people who aren't at their
peak be reverted back to what they thought was their best.
ie John's best was when he could walk, Jin when he could father
children,
Rose before her illness (cancer?)
