The VW looks clean, must be a Dharma flashback! Whoo!
Or is it...
Apparently lots of the main cast are seen walking around in fresh, clean Dharma jumpsuits, even the those that have already escaped the island (Jack, Kate, et al. ) along with lots of other extras, including children, also all dressed in clean, new Dharma gear. So I don't think it is a flashback.
So do the Oceanic Six return with Dharma to recolonize the island? Is this a new Dharma taking over after the last one failed?
My guess is it's either a new Dharma, or they return to the island in it's 1970s version and one of them are the "reliable source" from that "leaked"Comic-Con video. Why else would there be brand new VW vans?
