"Wait a minute, wait a minute, wait a minute!" Amy Pond screamed from across the Tardis, red hair crashing into her face with every jerk it made. "Are you telling me you have no idea what's happening?"
"Literally speaking, I have some idea." The Doctor calmly stated, tone doing anything but matching how he wildly flew around the heart of his ship. "We're crashing for some unknown reason and until a certain companion can be quiet, I cannot fix this!"
Amy's eyes widened in slight panic, completely ignoring the Doctor as she began to rant once again.
"Crashing? We're crashing?" Her Scottish accent held an edge to it that most wouldn't want to mess with. "You're telling me that you can save a planet from some giant oncoming threat or stop a ship from exploding with only your little screwdriver but you can't even control your own ship? Oh fantastic!"
The Doctor fought the urge to counter this insulting statement when the Tardis began to thrash even more violently. The screens showed him what he had feared from the moment any unwanted movement began. Numbers and letters, definitely not human, flashed across the screens. To any bystander or viewer this would be seen as complete nonsense, but to the Doctor it was a very bad message.
"Doctor!" Amy shouted from her very uncomfortable crouch. Object flew overhead threatening to harm anyone who stood in their path. "What...is...going...ON?"
As soon as the last word escaped her lips, everything stopped. The Tardis ceased all bucking and thrashing, going to so far as to even stop all screens and lights. It was eerily quiet.
"What's happened? Doctor?" Amy slowly stood up and cautiously walked over to where the Doctor stood leaning over the dials and levers that once burned bright with light. "Doctor? Oh great, you've gone mute. That'll really help this situation."
"Amy. Please just shut up." The Doctor straightened up, hand secured in his hair. "We've fallen out of the time vortex and unless I have time to think, we're stuck. This has only happened once, back when I was...cockier. If I'm correct, then we're in an alternate universe."
"An alternate universe? As in where everything's all backwards and opposite?" Amy slowly stepped toward the Tardis door. The Doctor pulled her back. "What? We can't go out? I want to see this alternate universe..."
"There's one problem...The me that was here before is partially still here and if the me that was here when I wasn't the me I am now sees me and the others who know about me see me as well, then there might be issues." The Doctor turned Amy towards him. "I can't go out until I've thought of a solution, and if you go out alone..."
"I'm not the damsel in distress like you're making me out to be. Just give me some sonic-y thingy or other and I'll be out." Amy moved the Doctor's hands from her shoulders.
"Some sonic-y thing? I only have my screwdriver!" The Doctor explained a bit angrily. He caught the look on Amy's face and got it. "Oh no. You're not taking my sonic screwdriver, I actually do need that to-"
Before the Doctor could protest, Amy shoved her hand in his jacket pocket and snatched his favourite tool. She ran outside and froze where she stood.
