The Doctor returns. (OPEN)
The Doctor had gotten distracted. It happened. Frequently, in fact, when global disasters weren't looming. He'd been working on an idea for a few alterations to the TARDIS's sensors, and 'a few hours' had turned into quite the long-term project. At some point Pond had wandered off. That was fine; the Doctor enjoyed having an audience, but he could perform solo if need be. He'd find her later - with the City such a confined environment, he wasn't worried about losing the feisty young woman.
By the time the Doctor surfaced from his work, the streets around his beautiful blue box had changed quite a bit. The door to the anachronistic police box opened and a shaggy-haired head popped out. The fellow took a good look around, pulled back inside, and shut the door.
A few seconds passed. When he stepped out, it was with a small parcel tucked under an arm. He turned, took care to lock up, and then started cheerfully down the street. He wanted food. Specifically, he wanted an ice pop. Lemon. There was work to be done, but it could wait the four or five minutes he'd need to find a vendor's stand. It felt like summer, and ice cream vendors were everywhere in the summertime.
