"S'fine. Didn't knock me over, now, did you? I just thought to warn you in case you continued on down the street like that." A quick shrug followed because Amy wasn't hurt, she was fine, he hadn't knocked anything out of her hand because she hadn't any purchases from the shop yet. It was just an observation as she was taking note on the surroundings as of late. The fact that this man was good looking didn't hurt, either. "Distracted? Yeah, I could tell." Amy smirked a little, because he was running out of a costume shop like he'd seen things he shouldn't have. It was kind of amusing to think of, even if it turned out that wasn't the reason this man was running out of the shop in the first place.
All thoughts of pleasantries with "Hello, I'm Amy" back to him died off when he introduced himself as the Doctor. Amy's eyebrows raised instantly because what?
"You're the what?" For Amy, the words "The Doctor" meant floppy hair, bow ties and tweed. Not... this. This man looked nothing like the Doctor she was used to. "How could you be the Doctor? How many of you are there, anyway?"
