At first, there was a strange grinding noise, seemingly coming from nowhere, accompanied then by the sand stirring on the beach a few feet away from where Lydia and Castiel were. Slowly, a blue police box began materializing, becoming more and more opaque. The noise stopped, and a few moments later, the door opened with a creak and the Doctor poked his head out and looked around. Spotting the pair on the beach around a bonfire, he knew this must be the place.
"Marshmallows anybody?" he asked, holding a bag aloft. He then trotted out of the TARDIS toward the people; he was wearing a black jacket over his hoodie and t-shirt, but no shoes.
