Fourth eye open: this time it's Sun.
In the caves we see the two skeletons (Adam and Eve). Speculation on their identities raged for many seasons until we finally found out they are the Man in Black and his "mother." The black and white stones they find initially mirror the backgammon stones, but also symbolize the light and dark aspects of the Man in Black, Jacob, and their mother.
Charlie yells that he's allergic to bees, but is stung many times and suffers no apparent ill effects.
Sun's revelation that she can actually speak English was a big surprise. I didn't see that coming at all.
Charlie's guitar and guitar case are an early symbol of recurring motifs. Hurley must bring a guitar case with him on Ajira Flight 316 later in the series to complete the circle.
Watching the episodes in quick succession makes it easier to remember things that happened a few episodes back, especially since little time has passed on the island. Jack, in desperation, ask Kate what she did. She reminds him that he had the chance to find out already. That did happen a few episodes ago. If you watch the show with a week between episodes, you might not remember that. Or perhaps you might. Depends on how good your memory is.
One of the best parts of the series is seeing the passengers interact with each other and the rest of the crowd at the airport before my flight. Seeing parts of other characters flashbacks interwoven amongst their own is very cool. Eventually you hope to get a complete mosaic all that went on.
This split of the survivors into two camps, the beach and the caves, is foreshadowing of another, more contentious split later on. Right now the split is over logistics. The one later on is ideological: Jack against Locke.
Seems very odd for episode entitled, "House of the Rising Sun," to not include at least part of the song, "House of the Rising Sun." But we did get was Willie Nelson. Yeah, that makes perfect sense. And Hurley, why are you wasting the batteries on the Walkman?
