The Doctor woke to the sound of loud moans and slight whimpers. Suddenly, he leapt up from his spot on the floor and dashed to the bed. Clara lashed and cried out in her sleep. The Doctor grabbed her face in his hands.
"Clara? Clara! Clara wake up," he cried. "It's just a dream, Clara. It's just a dream. Come back to me, Clara. Wake up." He kissed Clara's forehead. He closed his eyes and touched his forehead to hers. "It's just a dream, Clara. My Clara. Just wake up."
Clara awoke with a gasp. She stared up at the Doctor, fear etched into her face.
"It was only a dream, Clara. You're safe now. I've got you," the Doctor whispered.
"I was a Dalek. There was metal everywhere. And eggs. There was eggs. And there was you and another man and a woman. I'm a Dalek. I am a Dalek!" she cried out.
"No, Clara," the Doctor said firmly. "You are not a Dalek. You are my impossible girl. You are Clara Oswald. You are the daughter of Ellie and Dave Oswald. You have saved billions of lives. You have looked into the eyes of danger without flinching. You have traveled through space and time. You saved a tired, old man from himself. You taught that man how to be happy and have fun again. And you, my Clara, are human."
Clara looked into the Doctor's eyes. "I am human. I'm not a Dalek. I am not a Dalek because I am human." The Doctor smiled, but quickly frowned and pulled away from Clara as her eyes widened in shock and she sat up. "And I'm a genius," she whispered.
"Of course you are," the Doctor agreed as Clara shot out of bed and started opening the files of the victims.
"No, no, no. You don't understand," she said urgently, flipping open the last file. "Do you remember what you told me in the Dalek Asylum?"
The Doctor looked at Clara in confusion as she turned to face him with fear burning in her eyes. The Doctor just shook his head and stared at her blankly.
"You said, 'You're a genius and the Daleks need genius.' Every single one of the victims was head boy or girl at their schools. They graduated or were going to graduate at the top of their class and were the most likely to succeed. All of them had full ride scholarships to the most prestigious universities in the world or had jobs lined up that payed them in nine figures at the minimum. Each of them were amazingly good at strategy games and puzzles."
The Doctor rushed forward and looked at all of the files.
The Doctor quickly kissed Clara on the forehead. "Oh, you are a genius! That's the connection. They are all geniuses. Oh, Clara! You clever girl."
Clara cut off the Doctor. "But you forgot what else you said, Doctor. You said two more sentences after that," she whispered.
The Doctor's face paled. "'They didn't just make you a puppet. They did a full conversion.'" Clara nodded as the Doctor blanched.
