The Doctor poked his head out of the TARDIS.

"What's all that about, eh?" he said, patting her doors.

He closed the door and walked back to the control panel.

"We're stuck, aren't we?" Rory said.

"Yep," the Doctor answered.

"Can you fix it?" Amy asked.

"Nope," the Doctor said.

"So, where are we?" Amy said.

"A high school," the Doctor said, fiddling with some controls.

"Thought I'd left that behind…" Amy muttered.

The Doctor kept leaping around the control panel, trying to figure out what was wrong with the TARDIS.

"Well, she's shot for at least three days. Poor old girl's tired," he said. "We might as well explore."

"Doctor, it's a high school, what is there to explore?" Rory said.

"The thing about this high school is, Rory, that it's empty. It's the middle of autumn and it's empty."

"Where exactly are we?" Amy asked.

"Earth, 2013. More precisely, America-" The Doctor licked his index finger and held it to the wind "- Colorado."

"Great. Prairies," Rory said.

"No, no, no, Colorado's got lots of great things!"The Doctor defended. "Denver's a nice city, and there's skiing, and… And… Well…" He struggled to find other good things about the place. "Well, it's nice, just go with it. That's what you usually do."

Rory and Amy shared a raised-eyebrows glance, and followed the Doctor out the door.

They stepped into a white, fluorescent-bulb-lit hallway. It was lined with tall black lockers, with small silver numbers on the top. The floor was dull yellow linoleum, with black tiles every few feet. Hallways split off every twenty feet or so, with wood laminate classroom doors.

"Well, this is cheerful," Amy said.

The Doctor spun on his heel.

"Amy, listen, if you don't want to be here, go back to the TARDIS. It'll be cold and dark, but I'm sure that you will be much happier there than you are here. Obviously you're in no mood for adventure right now," he snapped.

Amy looked taken aback, but only slightly.

"Fine…" Amy said. "If you really feel that way, I'll stick around…"

Rory and Amy followed the Doctor down the hall. At the end of it were fire doors, which had fallen shut. The Doctor soniced it, and waltzed through as though nothing happened in the last five seconds. It led to a corridor running perpendicular to the hall they had previously been in

"This school reminds me a bit of the Time Lord Academy back on Gallifrey, all sparse and-" he began. Then he stopped. All of a sudden, he just stopped.

His gaze was trained on a dark shape at the end of the hallway, near the base of some stairs. It was crumpled, broken, and most certainly helpless.

He approached cautiously.

"Rory, come here," he called.

Rory complied.

"What does this look like to you?" the Doctor asked.

Rory looked the person up and down. It was a boy, probably no more than 18, with short dark hair and an athletic build. There was a long tear running across his stomach.

"It looks like he was attacked," Rory said, pulling back the boy's shirt, "But by what I don't know."

Amy had come to kneel by them.

That's when they heard the gun cock behind them.
