ADDRESSING
To continue the previous post: by addressing the viewer's expectations, you let him know that you're aware of them and you don't plan to disappoint him. When Ephraim doesn't tell Amy, the audience needs to know the ep is not going to turn into an after-school special about the perils of lying. (You could even -- though this is lazy writing -- have Bright tell Ephraim, "Life is not an after school special.") And then you have to be sure not to disappoint the audience.
Remember, they watch a lot of TV. Probably way more than you. They may not think about it too hard, but after the first few thousand hours of TV, they know when something's been set up. If all they're doing is waiting for the next shoe to drop, they'll probably click over to
Battlebots, where anything could happen.
