Hope had been leaving Rory that he'd ever track down that blue box in this town. But hearing a voice with an English accent gave him some hope that he was, in fact, somewhere in England and that Amy was close by. He turned and looked the blonde over. She seemed fairly pretty (though Rory would always prefer a certain redhead. He had married her after all) and looked to have an honest face and eyes.
"Yes, I am actually," he said, remembering to answer before she thought him an idiot. "I'm actually looking for my wife, Amy Pond. And our d-friend, River." He doubted saying daughter would go over well if this woman asked him to describe River. "We were...traveling together and got seperated. So...um, could you tell me what town this is? How far it might be from Leadworth?"
He hoped and prayed that this woman would be able to help him. And he'd wait to mention the Doctor. At least for now. He wasn't sure yet still if this was in fact Earth or some planet that humans had colonized. So he'd wait to ask that question of where the Doctor was and hope he was close by.
