For all you Lost fans, last night’s episode was filled with hidden clues. The biggest came when John Locke was trapped under the door, and a diagram was revealed on the wall. While the producers of the show only wanted you to see the diagram for a second, thanks to modern technology we took a screen grab in order to decode its clues. Unfortunately, we still have no idea what it means. So we’re putting our faith in you diehard fans, click on the diagram and tell us what the F it means!
