After rewatching Jughead there are a few things to mention.
No one has mentioned the paradox. Not the time paradox, but the fact that Locke has to get off the island so the O6 can go back. Locke who so desperately wanted to stay has to leave so others that wanted to leave can go back. That's funny.
Juliet is remarkably calm about all this. I wonder where that's leading.
Juliet also call Latin the language of the enlightened. Among the definitions to this I found were...
1. To give spiritual or intellectual insight to
2. rational and having beneficial effects
3. people who have been introduced to the mysteries of some field or activity
I still think enlightenment goes to the gods thing, but you have to see that the word was used deliberately.
The episode "The Long Con" has long seemed a metaphor for things in the show. Sawyer was a conman. Ben is the ultimate con artist. It's my contention that Jack is conning Ben to get back to the island and that Sun is conning Kate to get to Ben. Hell, even Hugo conned Sawyer into being nice. But I think we may have another con going on.
I didn't see it until re-view, but she jumped on the "you're lying" bit pretty quickly and agreed to go to LA before she was even asked. And if you think back, early on she was ready to give up on Des. In fact she asked him to leave and said she had moved on. But then we find out she's searching for Des, has a listening post and ends up with a boat near the island.
So suppose, just suppose she was searching for Des all that time because of her father rather than for love. Not necessarily because she's working for dear ole dad, although that would work, but because she knows of and believes in the island and its properties - so she wants it or to be in control of it for her own benefit.
What a con job that would be.
