The Doctor was not happy. He was sat on a school bus filled with screaming miniature pudding brains. Clara had come to the TARDIS the day before and begged him to come and help out. F course he immediately said no and there was no way in this universe would he come and help. The next thing he knew was he was getting ready to get on the bus and Clara was grinning smugly at him. The whole thing had been a nightmare and he'd only been on the bus for 5 minutes. He had already threatened to throw one year 11 into a black hole for hitting him in the head with a water bottle he'd thrown. He looks at Clara who was sitting next to him.
"Where are we going again I think I blanked out when you were explaining to me" He grumbles at her. Clara rolls her eyes at him.
"I told you we're going to the sight of an old power station from the Second World War" She spoke in a patient and calm voice, knowing today wasn't the day to wind him up. The Doctor looks t her more annoyed.
"What's so interesting about that? Even if it is still there it's hardly going to teach them anyting is it." He raises his eyebrows at her. Clara considers the point for a moment then shrugs
"Yeah alright fair enough that is a bit strange but it was Mr Jones idea" She motions to the teacher at the front of the bus who was looking straight ahead.
"Look Doctor just relax and have some fun it's not like this will be dangerous or anything." She says with a small laugh.
Eventually the bus arrived at the destination and everyone climbed off the bus and looked around. If there was a power station there it was completely gone by now. The kids instantly started running around the large field taking selfies or whatever teenagers do these days. The Doctor scanned around with his sonic and something felt quite wrong to him but he wasn't sure what. He looks around and sees Clara and walks over.
"When you said a field trip I didn't think you actually meant a trip to a field Clara" He raises his eyebrows at her. She grumbles at him.
"Oh ssh this isn't my trip is it" She was looking around a bit confused as well. Mr Jones the other teacher came to the centre of the field and called out in a soft lo voice.
"Settle down kids." The Doctor rolls his eyes thinking the kids would never listen to that. But he was surprised when every single kid moved to the area they were standing in. Mr Jones speaks out to them all.
"So boys and girls, this is the sight of a huge power station during world war 2. The British were desperate to gain an advantage over the Germans so they did anything they could to win One thing they did was to harness their own power supply and develop weapons from it so they created the power station. Now can anyone tell me what energy voltage is needed to override German systems?" The Doctor was listening to all this annoyed. He believed that what this man was saying was complete nonsense so he spoke up.
"Excuse me are you an idiot or something. That would never have happened and there are no records of anything like that happening. But in theory if that was true then the correct voltage would be…" he was about to say the correct calculation when a student called out.
"1.345 metre square of qubert-watt voltage with a magnitude of 666 times the maximum" The student said it confidently. The Doctor frowns as this was the exact right calculation. The Doctor leans into Clara and whispers.
"Is that child a science genius?" Clara looked equally as confused.
"Um no actually not at all. He's actually terrible at science. So how the hell did he know that?" The Doctor shakes his head and continues pacing around.
"It doesn't matter it's all theoretical there is no power station. Look at this place there is no ruins no signs nothing. This idiot teacher doesn't know anything." Mr Jones didn't look offended at all and smiles at him.
"Do you really believe that a secret power station would be built on land? Of course not you fool. It's underground. The whole thing was shut down though. But all that power is still there. The power that can destroy London and it would take the right mind to use. Luckily I'm here." He takes out a device and presses a button. Suddenly there is explosion ad energy bolts shoot out fro the ground and one hits the bus they were on and blows it to pieces. A staircase appears in the ground leading underneath the surface. The Doctor frowns and steps forward.
"Okay so it's real. Who are you and what do you want it for?" He growls at the teacher. The teacher laughs.
"Oh do you think you can stop us do you old man?" The Doctor glares even more.
"I will or die trying" He goes to grab the man but one of the students steps in the way and throws the Doctor threw the air and he lands in a heap on the floor. Clara gasps and runs over to him.
"Doctor what the hell is going on?" The Doctor jumps up dusting himself off.
"I have no idea. You what are you doing explain." Mr Jones laughs and grins.
"Children lets show our friends who we are." As one M Jones and the children all start to transform. Their features blurring and all of them grow in height and their bodies turn to red and their faces all identical. Clara screams and jumps back as she sees what they are. The Doctor glares as he watches it all.
"A class full of Zygons who now have the power to destroy the planet"
