'Lost' is awk

Loving the last season of "Lost" but one thing is bothering me. Every time a character interacts with Smoky/Not-Locke/Man in Black, I just feel like they're dancing around a MAJOR issue. Not-Locke is always talking about how he wants to leave the island and the rest of the cast (Richard, aside) is just nervously going along with the plan. Not-Locke HAS to know something is up, right? Like, his followers are totally dragging their feet on this "we're going to take the Ajira plane off the island" thing.

All they have to tell him is "Dude. Leaving the island sounds great and all and we want to help you out, but everyone else says you're THE absolute evil that will destroy the world and if you get off the island it will be the end of everything, or whatever... So I guess what we're trying to say is, like, good luck or whatever, we can't help you out anymore. The whole cork/wine thing..." Is that so hard?!
