A/N: Hello readers! This is my first attempt at a crossover story. Hope you like it! Oh, and don't worry, River will be in it soon enough...
The Doctor ran down the road. There were people staring at him as he zoomed down the street. Amy and Rory were right behind him.
"America is a big country," he thought to himself. They weren't exactly sure what city they were in, the Doctor had just decided to take them there. He looked back. The strange men were hot on the heels of Amy and Rory. The Doctor hoped today was not the day that he loses them. He looked back again, to see Amy trip. He turned his head, but it was too late. He ran straight into the person in front of him. He fell flat on his back, and so did the kid he ran into. The strange men suddenly disappeared. Amy was laying on the ground moaning. The Doctor sat up.
"Sorry, I wasn't looking where I was going," said the Doctor, helping the kid to his feet. The Doctor decided he looked to be about twenty years old.
"That's alright, I'm fine," said the man. He brushed of his pants and walked away. He turned the corner, and the Doctor noticed he left his phone. He put it in his pocket and ran to Amy. Rory was helping her. She was still on the ground. She held her leg and whimpered. The Doctor and Rory helped her up. They carried her back to the TARDIS. Her whole leg was covered in blood. She had snagged it on a nail as she fell, cutting her whole leg from her knee to her ankle. The Doctor brought her into the medical room, a room she had seen often. He took a shot with a blueish liquid and jabbed it into her arm.
"For tetanus," he explained. She looked feint at the sight of all the blood. She could not speak, she was in shock. The Doctor got a rag and started to dab the blood on her leg. Rory grabbed a rag too. They cleaned up her leg and the Doctor got a needle and some thread. Amy saw it and widened her eyes. She finally could talk.
"Whoa! You are not sewing me up until you've made my leg numb. It is hurting like crazy," she grunted. She was being very brave. A normal person would have been in tears. The Doctor got another shot and injected it into her leg. She cried a bit, then her leg went limp. She could not feel a thing. The Doctor put some disinfectant on her cut, and then proceeded to sew her up. He finished quickly and bit the thread. He got a bandage and wrapped her leg up. It started to bleed through a bit. Rory kissed her forehead, and the Doctor grabbed her arm and helped her stand. She cringed. It hurt to stand, so the Doctor brought out a strange looking contraption.
"What is that? It looks like a shoe," said Rory.
"It is a shoe, or rather a pair of shoes," he replied. They looked to be just a regular pair of high tops, but they weren't exactly regular. The Doctor slipped them onto Amy's feet carefully. He flipped a hidden switch on the back of them. She started to hover. Rory held her arm as she hovered around. She was a bit wobbly at first, but she eventually got the hang of it. She could move around the TARDIS without putting pressure on her leg. The Doctor remembered the phone he had in his pocket. The TARDIS seemed to have a liking to it. Being curious, he plugged it into the console. He examined the contents of the mobile cell phone. His eyes grew wider and wider as he looked at the programs downloaded onto it.
"That is very strange. Very extremely strange," said the Doctor to himself.
"What? What is it?," asked Amy. The Doctor stared at the camera on the back of the phone. A laser started to come out of the back.
"Oh dear, this is not good," said the Doctor, as they disappeared into The Grid.
