The Doctor was walking around the merry streets of alternate universe London with a silly grin on his face. He left Amy and Rory to do whatever they wanted to do and they were gone for roughly an hour. 'I wonder what they're up to,' The Doctor thought to himself as he then felt both of his shoulders being tapped. Turning around, he saw Amy and Rory.
"Doctor! We've been looking for you for thirty minutes!" Amy exclaimed. Rory simply nodded his head and said something among the lines of, 'she's right.
"I'm very sorry Ponds. Well, how is this London for you? Is it interesting?" The Doctor asked with a wide smile.
"It's been fun but after a while people started to approach us and ask for pictures," Rory explained. "They were calling us names we didn't recognize."
"And what are those names?" The Doctor asked.
"Karen Gillan and Arthur Darvill," Amy replied.
