[Daemonia]

I don't buy it, that they're driven by greed. Stephen wants normality - as illustrated by the dinner scene. If anything, Stephen is not so much protecting his 'stuff' but protecting his illusion that things could be normal again. The bikers' arrival intrudes on this fantasy and jolts them all back into the real world. You say they could take off in their chopper - but, as Dr Logan astutely pointed out in DAY, where would they go? Where could they run? Think about it, they're still trying to figure out what's going on - wouldn't you also kind of hang out somewhere safe and wait for news reports and try and build a picture of what's going on? Remember, our survivors here don't have the benefit of the knowledge that we, the viewer have. They're confused and bewildered. How far has the plague gone, how far reaching? Is there anywhere truly safe they can go to? Is it a global phenomenon? Just what the hell is it? Each of the survivors has a different coping mechanism, for Stephen it's the comfort of being around familiar things - it's not greed, it's reassurance. He's happy purely at the fact that there's enough resources in the Mall to sustain them for quite some time - again, not greed, but reassurances of safety, of normality. He's angry that the bikers are threatening his safe haven.
