Only six episodes had originally been ordered for season four and the production team had planned to make that short season the best they’d ever made. Twilight used newly-acquired Japanese mecha in Denver and Fargo against terrorist and cyberterrorist foes, and the ratings of the first three episodes all but forced the network to lengthen the season. And that allowed the writing staff to slow the story down, splice in some good character episodes, and reveal the big bad much more slowly. It gave season four an interesting arc, from frenetic beginning to slow middle and then a ramp back up to the season finale.
