There are story-room sessions where you think about the big picture, like a novel, but once you have certain things in place, you have to treat each episode like an hour of TV, and think that maybe this will be the only episode that anyone will ever watch. You want to have some sort of beginning, middle, and end to the episode, even if you have storylines that are carrying over. You still want it to feel like a cohesive hour of entertainment. And you can't think about both at the same time.
