Desmond coaxes Charlie, Hurley and Jin on a trek across the jungle after experiencing one of his future-prophesizing “flashes” -- but is he purposely placing Charlie’s life in harm’s way? Meanwhile, Kate turns to an unwitting Sawyer after seeing Jack alone with Juliet. Guest starring are Sonia Walger as Penny Widmore, Jack Maxwell as Derek, Joanna Bool as Ruth, Andrew Connolly as Brother Campbell, Andrew Trask as older monk and Marsha Thomason as parachutist.
According to the rumor sites something "fairly momentous" is going to happen tonight. I'm just glad they're going to have another Desmond centric episode.
