Like yahtzee63, I had all kinds of love for Jin's adorable, perky dad. And the ending was heartbreaking. I don't really understand why Jin would just give up at this point, but there's always the chance for him and Sun to reconcile later on. (I suspect Jin is not long for this world, though. Some major character has to die [and stay dead] before the end of the season, and losing Jin makes the most sense, to me. Some have suggested Hurley, but dude, I would cry so hard I don't even want to think about it. Not to mention that it seems pretty blatant to kill off the one character on the whole show who isn't slim and buff and gorgeous. This isn't Baywatch, after all.)
A few random notes:
What? Why are you looking at me like that?
Anyway, it pretty much goes without saying that I love this show and can't wait for next week. Only don't hurt my Hurley, dudes! He gets cramps when he runs!
