I mean, we know in general we'll avert a terrorist threat or conclude the conventional story, but we begin the year sort of pretending we have the first four to six (episodes). But even as we're writing those, they change. And I think one of the reasons the show has the quality it does . . . is we're so critical and so we revise ourselves. We revise it again. And in that process things just change too quickly to plan ahead too much.  -   Howard Gordon     Quotes
