Clara's POV

"D-D-Doctor, I... I really... I'm so sorry, it wasn't... Please, just don't think that I meant to... Doctor," I stuttered, and my hands were beginning to shake. "Darling please," I pleaded with him, but his eyes started to turn cold. "You have to – you have to understand, that wasn't me..."

So much for not telling him.

"What was it then?" he demanded, his expression ablaze with anger, sadness, and – something else. Something much more dangerous. I felt my lower lip begin to wobble, and I had to look down at the metal floor and steel myself so that I didn't cry right there and then.

"There's a – a thing, in my head. It got there yesterday, I'm so sorry Doctor, I couldn't... I didn't want to tell you... I didn't want you to worry..."

"Tell me Clara. Tell me now, tell me what made you decide to tear apart my ship."

"It's a Cyber Planner!" I shrieked, and his frown immediately disappeared as he took my hand.

Stupid man, Cyber Clara said.

He's not stupid. He's perfect, I replied sharply. He loves me, and he hates you. We'll get through it together, and you'll be long gone.

"Why didn't you tell me, Clara?" he asked me quietly, voice trembling in a way I hadn't heard before. I never thought hosting a Cyber Planner was that bad. Like sharing an apartment, but with a home wrecker. "I didn't want you to worry about me," I told him honestly, and he looked like he was about to cry as he turned away from me, running his hands over his face. Lines had appeared where I hadn't seen – or maybe not noticed – them before. "Clara, this is important," he said, turning back around to face me, "the day you said you had nightmares. Was it really a nightmare?" I shook my head sadly. His eyes widened, and he pulled me into an embrace. That's when I felt tears start to drop on my head. "Oh, Clara," he choked. "You beautiful thing, you pressed the button." I tried to smile up at him, but it came out more like a grimace. "Why did you do that?" he wondered aloud to the TARDIS ceiling. "Why would you do that to yourself?"

My body trembled, and a large sob hacked its way through my chest as I collapsed into his tweed-covered arms. "It... It said it was going to go after you, Doctor," I managed to tell him between my tears, "I couldn't let it... her... I couldn't let her take that from you. I couldn't let her get to you." He placed a hand in my hair and kissed my forehead briefly, wiping the tears from both our eyes. "You pressed the button, Clara. The Cyber Planner, Mrs Clever, she's fully integrated and stuck there. Forever. She's going to take away more and more of you until there's no Clara left. You'll be an empty shell doing her bidding."

It took everything in me not to start crying again. Well, I decided, I was going to go out fighting.

"Tell her that you love her, Doctor," I said to him smugly, "while she's still with you."
