I try to remind SHTF / Preppers the author / producer of Revolution is the same man behind Lost. They are reasonably good entertainment with zero sense of reality. That said you can pick up a few things, but they are probably stated elsewhere. For example in week 1 or 2 the girls found themselves prisoners of thugs, and offered them a bottle of liquor and thug one drank it and of course died of the poison they added to he bottle. Nice move.
