SPOILERS! Ok, they were warned! LOL
More clues? The flashback didn't advance the story timeline at all. Other than Desmond having that near death experience, all it seems to imply is that he now believes in Fate and that he was meant to be there. Now he can join Locke I guess in some island ritual. Personal, I's rather see Sawyer and Jack perform a different kind of island ritual! LOL Sure, toss Charlie in too and we'll call it a three way!
What did we learn really? That the photo Desmond had with him was really a recreation, not an actual location. (PS: I was in London at that exact spot. I don't recall any photographers though)
We learn that Pennelopes father is a real asshole.
We saw Desmond turn the key, but we still don't know what really happened. An explosion and Implosion? There was debris everywhere and he wakes up naked in the jungle.
Hell, we got a better clue the week before. Remember when Jack was talking to big Tom in the operating room? Jack says: "Why don't you just contact the mainland and get help. You obviously can come and go." Tom replies: "Well, ever since the sky turned purple that day...." then he was cut off.
So are we to assume that when the Hatch blew up they no longer have power to radio/call out to the outside world?
did you pick up more than I did Meryl?
