That's Very Me

Martha

"I can't believe I'm doing this!" Donna yelled excitedly.

"No, neither can I. Oh oh, careful! Left hand down, left hand down!" He shouted. Emma slammed the lever down just in time. "Getting a bit too close to the 1980s."

"What am I going to do, put a dent in 'em?" Donna said, completely sarcastic.

"Well someone did." A cell phone rang and all three froze before Emma reached forward and passed the phone to the Doctor. He looked interested by what was being said. Emma managed to avoid a supernova, knocking Donna out of the way in her efforts. Emma was dashing around the console, Donna trying to get out of her way. Emma tripped over Donna's strategically placed foot and crashed into the Doctor. The Tardis took that moment tilt wildly sideways before landing, sending both the Doctor and Emma flying out the doors. The Doctor landed on his back, Emma on his chest. She was blushing bright red and stammering apologies. They heard both Donna and Martha burst into laughter. Emma climbed off the Doctor who was blushing, but still grinning at Emma.

"Who was driving?" Martha asked chuckling. Emma blushed and Martha's eyes widened.

"He let you..."

"Er...he was busy, and there was a supernova and well...yeah." The Doctor looked proud.

"Emma, that was brilliant!" He scooped her into a giant hug before rushing to Martha to hug her too.

"So, what's up?" Emma asked. Martha gave the girl a look.

"We have a bit of a situation." Martha said delicately before raising a radio and speaking into it. They watched as UNIT swept over the factory before them.

"Is that what you did to her? Turned her into a soldier?" Donna asked him. Emma visibly winced, briefly drawing the Doctor's attention.

"I was a soldier once Donna." Emma said. All three turned to stare at her in shock.

"You..." Donna didn't finish as Martha put a hand on her shoulder in understanding.

"Some of us have got to stay behind. So we've got to work from the inside. And by staying inside maybe we stand a chance of making them better." Martha said softly. Emma nodded and took a deep breath. They were lead to the mobile command center where the Doctor balked at getting a salute.

"I've read all the files on you. Technically speaking, you're still on staff. You never resigned." Colonel Mace said.

"What, you used to work for them?" Donna asked, clearly not expecting the answer.

"Yeah, long time ago. Back in the seventies. Or was it the eighties? But it was all a bit more homespun back then." Emma was studying something she probably wasn't supposed to be, making the Doctor grin. Donna was busy yelling about the way the workers were being treated. Martha had him looking at the Atmos device. Emma peered over his shoulder and gasped. She snatched it up and soon had it disassembled. She was frowning down at a vial. She proved her point, breaking the vial and dropping it into a mouse's cage. The mouse died and she lit a match, dropping it in. The gas caught fire and burned up. The Doctor was giving Emma a strange look. Realization dawned on him, visible on his face.

"You've seen this before." He realized. Emma nodded stiffly. She had noticed something odd about Martha. She'd disappeared at one point and came back acting strangely. Emma silently crept down an abandoned hall. Two men stood guard over a room. Emma took a great breath and allowed a tiny trendle of gold light escape her fingertips. It wound toward the men, who were both knocked unconscious. Emma hurried forward into the room and gasped. Martha was hooked to a machine of complex wires and electrodes. Emma rushed forward and carefully untangled her. She caught Martha and dragged her back. Elsewhere, the Martha duplicate fell into a puddle of white goop. The real Martha started awake, clawing at Emma, who tried to shush her. She froze, recognizing Emma. Emma pulled her sweater dress off, leaving herself in a tank top and leggings. Martha pulled it over herself and Emma attempted to get her out. A screen fuzzed and a potato like creature appeared.

"Halt intruder!" Emma sighed and turned, gold eyes flashing. The creature looked at her oddly.

"You're something different." Emma grinned ferally.

"I am." She slashed a hand and gold exploded and she made her escape with Martha hobbling slowly beside her. When they entered the main hanger, guns were immediately trained on them.

"Put that down!" Emma snapped, go find a doctor, not the Doctor. Miss Jones needs to be examined for injuries." The private sputtered, but did what she said. The doctor arrived before the Doctor and Donna did. He looked relieved to see them both. He hugged Martha and then hugged Emma to him tightly. She was whispering something, obviously not good news. The Doctor glowered, and decided it was high time to visit the inventor of Atmos. He, Emma and a soldier named Ross went. Luke Rattigan was expecting them. While they traded insults, Emma and Ross sighed.

"Oi!" Emma finally called. They both shut up.

"If you two are done comparing IQs?" Luke smirked at the Doctor, but Emma towered over him.

"I said enough. Now what is this? Looks like a...no..." She whirled on Luke. "What have you done?" Luke's smile dropped into confusion as did the Doctor. Ross seemed like he was starting to understand. "Great big brains, the both of you, and neither of you can see what's wrong?"

"What?"

"Oh, I should have known! Sontaran technology Doctor! Sontaran! They'll kill us all!" It was a mad dash back to UNIT. They had to lose the jeep, and run the rest of the way. It had already started, the poison gas filtering everywhere. It was wrecking havoc on even the Doctor's lungs. And then the massacre. Poor Ross, brilliant Ross died because Mace was too stubborn to pull back. The Doctor was furious, yelling at Mace, and then Martha had an idea.

"Doctor, the Valiant. You can use it to clear the air over UNIT." He grinned at his former companion.

"And there are weapons on-board." Emma smacked her forehead.

"I got it!" She cried, waving paper around delightedly. " the gas, the 10% we couldn't identify, it's Caesofine concentrate. Clonefeed. It's clonefeed!" The Doctor's eyes lit up.

"Ooh. Oh,oh,oh. I got it! Atmospheric converter. At Rattigans!" The Doctor said. And the Doctor noticed, Emma and the Tardis were gone. Martha's phone rang.

"Make them mad." And then she hung up. The Doctor grinned excitedly and that worried Martha and Donna both.

In the end it was Luke Rattigan that destroyed the Sontaran ship. Emma was slightly upset about it too. While the Doctor helped cleanup, she got started on prep work. She handed the letter off to Wilfred to send after the Earth was stolen. She made sure her identity was foolproof and then she gathered her stuff, moving it to where she was staying. She made sure nothing would remind her until the end.

Martha came to say goodbye, hugging all three of them. And Emma felt the Tardis begin to move. Something was happening. They were all tossed around and Martha was yelling at the Doctor unnecessarily.
