The first time I saw the season 3 opener I thought there were 2 islands, but then Ben told Goodwin that if he ran he could get to the wreckage in x amount of time( can't remember specifics right now). This made me think that they were all on the same island if Goowin was going to run. What's the deal? How did Ethan get to one camp and Goodwin get to the other camp? I know they have a boat and a sub, but would Ben be left immobile - without the use of either? Is there a tunnel that those guys could run down. Where did that power cord that Sayid and Hurley both follow up the beach (Season one)originate?
