Good catch about Jack's beard and the time span. The writers really have dropped the ball here. I still like the show and will continue to watch it but they really need to get their act together in keeping up with all of this.
I think they've given up on having this show ultimately make sense. Lots of loose ends are going to be dropped. There are too many characters in the show, especially if there are a slew of *survivors* off of Tanjira Air or whatever the new plane crash was called....
I think the 3 year time lapse is important. The "time benders" that Sawyer/Juliette/etc were on only took what...4 days of actual time?
I think it's interesting that they are stuck in 1974-ish because would any of the remaining Losties really want to go back to the "World" in 1974? Is that any better a life than hanging out on the island?
If Christian and Claire are not dead...I'm going to burn all of my LOST DVDs.
I'm guessing we're going to get an Ethan as "child" reference this season...
