Discuss the questions that have no answers please.

Why are Jack and Kate lying about the others?
How many years is this flashforward?
How fit was Saywer in bed with clean hair, I mean, seriously?
& of course
Why is Aaron calling Kate 'Mommy'?!
Why is Locke still VERY VERY ANNOYING?!
Who else hopes that the boat has sank with Sayid in it so he never comes back again?
