The Flashback: I believe this is the first flashback this season. Well, for a Locke flashback, it wasn't really any good other than the fact we see how special he really is and how much the others have already been following him ever since.
The Island: Well, in Locke's camp (or what's left of it), they're just basically going round and round. The only thing they have to lead them is Locke's dreams and I don't think much people trust him on that. We discover something that they have been looking for for quite a while now, but it's what lies inside this thing that is most surprising.
The boat people are coming and I can sense an all out war.
