When I was watching "Dead is Dead", I wondered why the others hadn't moved into the Dharma houses yet when we saw Ben had kidnapped Alex. If Ben had killed all of the Dharma Initiative and was now living with the others, wouldn't you think that they would have moved into the houses by then? Then we see Ben pushing Alex in one of the Dharma swings a few years later. I am just curious why they were still living in the jungle when they could've been living in the houses. Any ideas?
