i thought this episode kinda brought things together from the two big seperated pieces, the others and the losties. kate and sawyer are back. we see the people on the beach haven't been forgotten. some light-hearted, buddy stuff took place. this is a good restart. now we can focus on kate, locke, and sayid's quest for jack/answers/escape. while the beach people do what they do-- get water, food, build shelters, and wait. jack and the others are in a funny spot. since all the drama with them has died down a bit, maybe we'll get to see what they've been planning all along and particularly what they have planned for jack.
episodes like this are very necessary. slow it down and kinda rebuild the tension again. the tension has been high for like 9 episodes. it's good to have some good vibes before another foray into violence, science, and cosmic conspiracy.
