Roll credits. Cue end credits scene.
A truck sat abandoned by the side of the road, in the middle of nowhere. It was a 1987 K-5 Chevy Blazer. It was Apple Red with white lower panels and tinted windows. This was Kat and Billy's, left behind after the Tardis dematerialized a few short hours ago.
Suddenly, there was a bright flash and a figure appeared, standing behind the van. The figure was a statuesque woman with blond hair and dark sunglasses. She slowly approached the truck, pulling a small hand-held device from her pocket. Aiming it at the car, the device began to make loud beeping sounds as indicator lights on the device began pulsing brightly.
Looking at the device, she took off her sunglasses to reveal piercingly stern blue eyes. Tapping an advanced-looking earpiece she wore in her right ear, she said, "Sir, we've found something."
