Twilight’s fifth and final season started by answering the questions everybody had asked during the season break. The camera panned down from a night sky to show an American infantry battalion moving towards the ruins of Detroit. It passed through the infantry fighting vehicles, showing grim faces as they tried to steel themselves for the battle to come. The camera shot beyond the column to show the defenders of Detroit ready for battle. They were obvious robots, and when they opened fire on the American force everybody understood what combat AIs could do when unleashed. Of course everybody knew the Islamic State of Detroit used them, but seeing them in full color action was a jolt to everybody’s mind.
