Series 2, Episode 3
As Sawyer, Jin and Michael find themselves ambushed by 'the others' and dumped into a camouflaged pit they soon get a new prisoner in the form of a woman... but it isn't long before she reveals her true colours. Back at the hatch, Jack and Locke are at loggerheads with one another when they each question the others intentions. As Kate is rescued, Sayid arrives just in time to save the world (apparently).
Dare I say it, but the whole thing seems to be getting a bit stale?
