Comic-Con isn’t Comic-Canon
In their final podcast for the year Damon Lindelof and Carlton Cuse cleared up the “issues” surrounding the Dharma video that was shown at last years Comic-Con featuring Pierre Chang. They confirmed that it was definitely Faraday behind the camera, and that the original plan had for it to tie in with the ARG (which got canceled due to the friggin’ global financial crisis), and that they’d originally planned for Faraday’s Dharma storyline to be told differently. He was going to remain on the island trying to convince Chang about what was going to happen in the future, but instead his storyline ended up with him leaving the island and working at Dharma HQ until his return 3 years later. They said there was always a chance that the Comic-Con material wouldn’t match up entirely with the true canon of the show, due to the material being planned/written long before work on season 5 began.
