Locke calls them their Adam and Eve, and they find a bag of shiny pebbles on their bodies; one black pebble, one white.
Sun secretly tells Michael that Jin saw him wearing her father's watch, and thought he stole it- thus revealing that she speaks English- something no-one, not even Jin, knows.

Charlie and Claire bond over imaginary peanut butter, and move to the caves.
Sayid, ashamed for resorting to torture again, leaves to explore the jungle.

------------

Okay, so that's the first third of series 1 done, and a lot of filler so far. Knowing Shannon and Boone don't last much longer makes their scenes less important. (Dreading AnaLucia and Ekko's scenes in season 2, and I hated them first time round.)

Unexplained so far (up to end of season 5):
1. The sudden, predictable rain.
2. The origins of the monster.
3. Adam & Eve.
4. Light vs dark. Pebbles, backgammon...
5. The island appearance of Christian Shepherd.
6. The disappearance of Christian Shepherd's body.

The last episode of season 5 certainly makes point 6 very relevant. Fake John was walking around whilst the real John was in his coffin. What are the implications of just one Christian if "Dead is Dead"?

I can't remember the Sun/Michael thing going anywhere, though it's heavily hinted at so far. Plus there's no sign of Sayid/Shannon attraction yet. At least the Jack/ Kate/ Sawyer thing has finally started since that kiss in episode 8, as she's been all about Jack until then.

Other than that, nothing unanswered is leaping out as yet, though I know of more to come over the next few episodes, especially concerning the children.
