Several new arrivals parachuted into the island, but the real solution would be to send in Jack Bauer and interrogate the truth out of everyone. "Where's the goddamn polar bear, DAMN IT?!" he could scream into Ben's ears. Well Jack, apparently he's gone on a sightseeing holiday to the desert and forgotten to bring any sun cream or parasols.
Fortunately, the new revelations in the episode are fairly startling and provide a momentary distraction from the frustrations. In particular, the footage of the wrecked plane at the bottom of the sea is rather shocking and very well realised. The image of the skeletal body of the pilot in the cockpit is poignant, but who on earth is it? Indeed, given the new elements being introduced, such as the ability to talk to the dead, perhaps it is from another planet entirely?
