In "The Candidate", Sayid ran out the watertight door and blew up. Watch this Lost Untangled and watch the door closely as Sayid explodes. http://www.youtube.com/watch?v=Mb04XjxPqpg
Then watch the scene as we saw it on TV: http://www.youtube.com/watch?v=Zl12dAn5gnY
Which one is the real one? I've seen various people on this site saying that Sayid saved the day by "getting the bomb off the sub", but I certainly don't think that happened. Could they mean that he got it into the other room and closed the door? I know it's petty, but I'm wondering why in one version it shows the door closing, and in the other it's just a bright light.
