As much as this episode jumped around, I found it very satisfying. Not in terms of answering enough questions, or not adding any more, but just in how full it was of tantalizing scenes and activities! But some of the points that stuck with me are:
** If Sun shot Ben, would the Island make the gun misfire a-la Michael's attempts? Either Ben has no fear of her pulling the trigger for that reason (so he can be as snarcastic as he likes), OR, Ben has fallen out of favor (and usefulness) with the Island and he is very afraid that she will shoot him (and his sarcasm comes from that fear). I'm not quite sure what to think about where Ben may stand within the Island's graces at this point, now that he's made so many misjudgements along the way.
** It was great getting to learn more about the B612s of course, so thanks very much to TPTB for living up to their promise of giving us Danielle's backstory! Who knew that they had been to the ruins/Temple?! So sad that they lost a war with Smokey and disappeared down one of his vents though. Why was Montand so casually asking for help after his arm was ripped off?! "Hey help! And by the way, could you send down a cappuccino?" It was nice of his colleagues to look for him down the hole, but what happened to them all?? Did they look into the eye of the Island like Locke did? Maybe Robert shot Danielle for the same reason that Locke shot Naomi, because she would have ultimately, and sanely, worked against the island's wishes.
** Seeing Jin as the wise islander with the B612s was very interesting. For so long he had to rely on the guidance of everyone else, but here he was almost in a leader role for them.
** Some time-skips come quickly and some take longer. It would be weird if it happened every 4,8,15,16,23,42,and 108 minutes, which would kind of connect it to the Swan venting protocol. I doubt if it does though.
** It worries me that Locke keeps saying that Sun wasn't supposed to leave the island. If she was meant to stay, does that mean that she and JiYeon were meant to die? Because they would have if she had not left.
** "So, you speak any other languages?" "Just Klingon." X-D
** In the first few seasons, we were told that the island was a good and healing place. Now we are told that it is death? I'm confused...again.
** I wonder if we'll see little Charlotte saying something to Mr.Dan in the past in a time-skip about not having chocolate before dinner, that would connect the past and the future? And, totally freak Dan out. I'm sorry that Charlotte died, and sorry if we don't get to see Mader in the show any more, she played the part very well.
** The scene where the well closed up and Sawyer is left holding the rope was incredible. Obviously the FDW surface hole was not natural, which begs the question: Why did someone dig an easy access well to the FDW, if the power source is so volatile and dangerous to humans? Wouldn't that be a bit like leaving the lid off of the Chernobyl chimney after it blew and was spewing out radiation?
** It never ceases to amaze me how Locke can be so brave and so cowardly at the same time, and Terry O'Q is such an amazing actor in portraying all the mental nuances of emotions that run through Locke's head.
** Does Dan know that his mother lives in a church spending her time working on the mechanics of the Islands movements? Can't wait to find out.
** It looked as if the FDW did rotate some when Locke made the adjustment, was that the moment that Locke gets bounced off the island? I suppose so, since CS was practically saying good-bye.
Update: Jo commented on her first article about this ep that we should probably be studying up on Charthage and Hannibal, which is a very good idea. Charlotte's babbling might not have been just all filler dialogue to show how crazy she was until she died. :-o
