really?
I've come to think the total opposite
I used to look for special meaning in the titles, but gave up after being disappointed
"LeFleur", ooh, new character.
Nope, nothing special, just Sawyer's alias
"Some Like it Hoth", there was so much conjecture on this board what as to what that could possibly mean. Turns out it was really nothing. Hurley's rewritting Star Wars. Nothing more. Took up about 25 seconds of the episode.
"Namaste", again, so much theorizing, "I bow to you". Who's doing the bowing ? And who are they bowing to ? A new leader ?
Nope. Its the equivalent of "Say Cheese !" when you get your picture taken.
I'm sure you can come up with something clever that the writers have actually done with the titles, but I'm going to go with the most obvious, lame answer.
