*TPD here. Hello all, this a prompt I got for the return of Mr Clever from foxgoddes07. This prompt is set in the Transitions universe, as will all of these prompts. I hope you guys enjoy it!*

"For the last time Clara!" the Doctor shouted as she screamed and ducked. "Get back inside the TARDIS! I can't protect you here!" He cursed and soniced the door behind them shut. That wouldn't hold them for long. "Clara Oswald, I am warning you!"

"What're you going to do?" Clara smirked. "Divorce me?"

"I've a good mind to!" the Doctor muttered irritated as he shoved her into the blue box. He soniced the TARDIS door shut and cursed as she soniced it open from the inside. "I keep forgetting you can do that," he said, more to himself than her. She grabbed his hand and tried to wrench him inside but he slipped into her arms and kissed her before wrenching her sonic out of her hands, slamming the TARDIS door and sonicing it locked. "There, now stay in!" he muttered, as the layer of wood between them shut out Clara's inevitable yells of anger. He turned to face the Cybermen as the door between them was blasted open and three Cyber units converged, their guns pointed at the Doctor.

"You will be upgraded!" one croaked. "You will become like us."

"No," the Doctor replied, diving to his left as they unleashed their Cybermites. The Doctor fiddled crashed open a control panel with his sonic and started tampering with wires and levers. The Cybermen just stood, watching. They were confident then, that the Mites would do the job. They covered the Doctor as he focused his only task on finishing the job. "Who da man?" he yelled, turning back to them as alarms started going off and in the distance, the explosions started. "Toodloo boys!" the Doctor grinned, throwing himself into the TARDIS as the Cybermen starting firing. He collided with Clara, knocking her to the floor as she pounded angrily on his chest. He kicked shut the TARDIS door and felt his mind slip away from him. The Cybermites. He had to protect Clara. The Doctor yelled in pain and then he was gone.

"Doctor?" Clara asked tentatively as he fell off her, sprawling in pain and screaming. "Doctor what's wrong?" He stood up, looking confident and commanding. She was immediately worried as he stared at the wedding ring like he'd never seen it before.

"Oh you're Clara. The Impossible Girl. I remember now. The Cybermen have been inside this brain before. Never extrapolated anything useful of course. I am…Mr Clever. Yes, the Doctor cheated us once before, but not this time. You're our insurance Clara Oswald. Try anything, Doctor and I will kill her with your hands. Would you like that? Clara!" The change in personality was alarming. "Get out of here," he warned her. "I can't control him. I may have to regenerate. I could get rid of him, get him out of my brain."

"But I'd lose you," Clara whispered and the Doctor flinched momentarily. "You'd change."

"You've already lost him Clara Oswald," Mr Clever sneered and opened the TARDIS doors. The Cybership that they'd been on was gone, and Mr Clever's face fell. "He blew it up. All of it. Well, we'll have to rebuild. Somewhere else. How about," he looked at Clara and smirked wickedly, a look that did not suit the Doctor's face. "Earth."

Clara stepped between him and the console and slapped Mr Clever so hard he turned into the Doctor, who yelled in pain and then smiled at Clara.

"Hello Clara," he greeted. "Now I need to regenerate. Or, find another way to get rid of the Cybermites, any ideas? Oh and before I forget or lose control, take this!" he tossed her a screwdriver. She caught it and ran over to the console. "There'll be something, somewhere in this ship. Any ideas?"

"He wants to go back to Earth," Clara warned. "Can we stop the TARDIS from flying?"

"Yes," the Doctor paused. "But anything I do, I can undo. Hello flesh girl." He'd changed. "Now then, let's take you home." He grabbed Clara's arm forcefully as she tried to run from him and his face disgusted her. Because his evil smile mutilated the kind and loving face of her husband. "What would your father say? Marrying an alien from outer space? Ohh he already knows. Well, I'll kill him first. And make you watch. Then, I'll turn his dead body into Cyber form. Would you like that Clara Oswald? Or would you rather I turned you first? Actually, I'm not allowed to turn you. One moment." He paused a second, like he was having an internal discussion. "Ah good, I've taken control of the brain. The Doctor allowed me access to 60% in exchange for your life. A promise I am about to break."

Clara stared at him in horror and then smiled. "You're forgetting something," she said and Mr Clever raised an eyebrow. "You're still in the Doctor's body and I happen to know that last week when we went skiing, the Doctor injured his left knee. And he's not properly healed yet. Sorry about this Chin-boy, I'll make up for it in bed later."

She kicked the Doctor in the left knee and he howled in pain as she ran. She glanced over her shoulder and saw that he had doubled over, unable to control his own body. She pointed her sonic at him and tried to scramble the Cybermites using the program he had installed. She swore. The Cyber Planner had control of his body. They'd made a deal, for her life. Clara didn't know what to do. She needed to fry the Cybermites. Something that wouldn't kill the Doctor. What would work against tiny robots? The TARDIS was making a noise and as she rounded a corner, she saw the Doctor/Mr Clever waiting for her. He smiled wickedly and Clara looked around for somewhere to hide. There was a door to her left and she flung herself through it, the Doctor right behind her. Of course, she realised. Swimming pool. Water. Run a low level current through it…

The Doctor followed her in and she prayed that this would work. Worst case scenario, the Doctor, her Doctor would regenerate. She didn't contemplate that option. She wasn't going to lose the man she loved, let him become someone else. Losing her Doctor would destroy her almost as much as losing the Doctor. She stepped to one side as he lunged and he crashed into the pool. Clara snatched up her hairdryer, left on the side from earlier on that day, when she'd been for a swim. She soniced it, targeting the battery power levels and then hurled it into the pool, praying for a miracle.

The swimming pool lit up, a crackling electrical energy passing through it. Mr Clever roared in pain as the electricity ran through him, the noise torture to her ears as it was the Doctor in pain. When the electricity faded, Clara jumped into the pool, swimming over to him as he lay face down in the water. She called his name and turned him, checking a pulse and relieved to find he was still alive. His eyes flickered open and she stared at him, tears welling up.

"So, not dead then?" she whispered. "No regeneration? No new Doctor?"

"Nope," he whispered. "I'm in a lot of pain though, could you help me out?"

"Doctor," she kissed his cheek. "My Doctor. We have the rest of our lives to help each other out."
