I really enjoyed this episode quite thoroughly. I'm pleased with where we are right now - Juliet scheming but the rest of the Others (and Locke) offscreen where they are more believably up to something, Desmond working out his gift (didn't he show up with a rope as a belt at some point? And possibly even help someone up? I don't suggest it Means Anything, I just think it's kind of neat. If it happened), even the Jack/Sawyer/Kate thing is okay in this small of a dose.
Of course, the Korean ghost story was great, and Hurley picking up Korean, and the way Charlie turned to get support from Jin in mocking Hurley's foot-race restriction. What language was Catch-22 in?
