Jack's actor.. Ethan something?? Got paid a one off fee "for playing a pivital role" or something and also signed him up for another season, which, was unfortunate. But you need Jack as the moral high ground otherwise Locke and Sayid will just go round stringing people up. I do agree though, everyone else can go apart from those you mentioned, maybe Saywer can stay as long as we dont see anymore backstory. Oh, and definately Walt, Michael and Danielle. The rest can go juggle dynamite. I enjoyed the ep. Something was definately powering UP though, because the sound pitch got HIGHER until Locke hit the numbers in, then the pitch lowered.
