Ever since arriving in Red Oak, Amy Pond had been doing a bit of investigating. Not the same sort of investigating as River was, with trying to figure out what was going on and why people were getting pulled here, but a different kind. It was a way to get an idea of what this town had to offer, what was there to pass the time until they were all able to return back to their proper time streams. If there was one thing Amy couldn't resist, it was a chance to explore and if Red Oak was it for now, she was going to see if she couldn't figure out every bit of this town the best she could. It also staved off the boredom that wanted to follow. Show a girl all of time and space and a silly little town in America wasn't going to offer too much excitement.
What Red Oak did have, however, was a Halloween store. A costume shop was something that greatly interested Amy Pond because if her job as a kiss-o-gram didn't say she loved dressing up, she didn't know what did. The TARDIS wardrobe had all sorts of outfits in it and she often went through it, piecing together a few things that were her style, but it wasn't the same as going through racks of costumes in a Halloween shop. So, she decided she would check out this Guises shop and see what it had to offer.
As Amy approached the shop, minding her own business, it was without warning that another person nearly bumped into her, in a move that would have surely knocked her down, had she been half a second quicker in her approach.
"Oi, you! Watch where you're going, yeah?" It was an immediate snap, as this bloke didn't actually run in to her, but he could have and that was enough. If or when she were to notice that he looked a bit out of sorts, she might be willing to ask if he was alright, unless he was getting chased out of the shop for being a pervert or something.
