There are too many sites that spend way too much time analyzing the fantastic show that is Lost. (Doc Jensen at EW and Sepinwall are two of my favorites.) It is great that the show's writers really seem to know where they are headed with only 22 episodes left. And I think we are going to learn a lot more about how time travel works in the weeks ahead.
But on a much lighter note, I just want to point out that every time I hear Sawyer's new name, LaFleur, it reminds me of my favorite commercials of all times: Ladies and gentleman, the McKenzie brothers and hockey legend, Guy Lafleur.
