Now I am confused. I had thought that "the world" thinks that Aaron is Kate's biological son, so there must be a world/island time difference for that to be plausible.

But now "the world" thinks Jin died in the crash, and Sun had his baby 9 months later. So we now know that island time must be roughly equal to time passed in the outside world.

So if Kate is rescued about 4 months after the crash, holding a 3 month old baby, everyone would know it is not hers. I guess we are to believe that they let her keep Claire's baby because it was "in the best interest" of the child, and everybody said that is what Claire wanted, etc.

Or it could theortically be her baby, born after the rescue, and she named him Aaron. But that seems highly unlikely.

Anyone think otherwise?
