The Package:
Seems we're back to the slow setup phase, with a little stupidity thrown in the mix. The stupidity I refer to being Sun's story. Smocke spooks her in the remains of her garden, and she runs away. She hits her head and suddenly loses the ability to speak English. Ahwha?

Did Yunjin Kim develop laryngitis or something, and wanted fewer lines for a while? I mean, this close to the end, what possible purpose could the de-evolution of a character serve? Oh wait, let me guess. When Sun and Jin are finally reunited, she'll regain the ability to speak English. I'm usually pretty forgiving of stuff, but this particular act just seems really dumb and pointless.
Then there's some setup for more plot points. Richard decides that the best course of action would be to blow up the plane to keep Smocke from using it to escape the island. This is, of course, not a popular option as the plane is also their only means of escape from the island.
Meanwhile, Smocke's camp is attacked by Whidmore's people and Jin is captured. This leads to some more pointlessness with no new information whatsoever. There is one nice moment, when Jin is handed Sun's camera and gets to see his daughter for the first time. Awwwwwwwwwwwww. Whidmore has brought a "package" with him to the island. Smocke sends Sayid to find out what it is. It's Desmond. Yay! Maybe things will start to look up a bit?
Oh, I didn't mention the flash sideways yet, because it's probably the weakest so far. Jin and Sun aren't married in this universe, but are still banging. They get in trouble with Keamy, who was actually being paid to bump them off. Jin gets captured, Sun gets shot, yadda, yadda. The flashes so far had at least given some character insight. This one really doesn't. It's a shame, since I like both Jin and Sun a great deal. Besides not being married, everything is pretty much the same for them. It was cool seeing Mikhail again, though. Since he had both eyes in this universe, I was fairly certain we were going to see him lose one in this universe. I was right.
