On getting the answers:
Lindelof:
"We answered all the questions that we wanted to answer. And our rule has always been: We answer the questions that were important to answer for the characters on the show. If Jack, Sawyer, Hurley, Locke, and Kate didn't care about it ... It's not that we didn't care about it, or that we don't acknowledge that the fans are curious about it, but we didn't answer it.

And that's all we're willing to say" ...
