The Kate/Aaron stuff made no sense in the context of Kate's scene with Jack in "316". If it was as simple as Kate deciding that she had to leave Aaron with Claire's mother, while she goes to search for Claire, why didn't she just tell Jack that? Why doesn't she tell everyone that? Why say "Don't ever ask me about Aaron again", which surely must freak Jack out? Doesn't Jack deserve to know that Aaron is OK?
I think the writers are too in love with the idea of turning everything into a mystery, even when doing so is uncalled for, and defies all logic.
That's a very good post, a very good point. I know there's been discussion here before about the lack of communication between characters and it looks like they're right back to that old mainstay, i.e. nobody tells anybody anything.
Having a mystery for the sake of having a mystery has been one of the most annoying parts about this show.
