I'm just finishing up Lost. In one of the last episodes Jacob is sitting around the fire with Jack, Kate, Hugo and Sawyer. When asked why he chose them to be candidates he said something to the effect that they were each all alone with nobody and lost in the world. He also tells Kate the reason he crossed her name off was because she was a mother.
But the Kwons were both married (so not all alone) and had a child, so why was one of them still a candidate (until they were drowned)? Is there any logical reason within the show or given outside of it by the makers? Is this just a case of "characters don't always tell the absolute truth, especially in Lost"?
