Remember the days when a B-plot for Lost concerned trivial things like a poker game to get back some medicine from Sawyer? Those were the days, huh?

This week's episode was entitled (with a loving wink) "Cabin Fever", a reference to both the increasingly-dangerous freighter and the trek to Jacob's creepy Ghost Shack. Following the destruction of the Barracks by the Freighties, Locke took Ben and Hurley on a journey to try to get back to Jacob's love pad in order to get further instructions.
