Production has begun on V's second season and we have our first look at the action from the set. It appears the red sky last seen in the V season finale is falling. Erica and Tyler, while attempting to escape the falling sky, don't have any protective gear on so it is safe to assume that this is not the visitors first step in their plan to poision the hunan race. But if not that, then what?
