In Clara's mind, there was silence. Nothing but her, on her own. And then, back in reality, she flinched as millions of cybermites flung themself at her. She cried out, falling onto her front as a Cyber Planner formed in her head. Then, in her mind, she saw someone like her, but there was metal riddled on the side of her face. She looked more cunning and monstrous.
'Hello?' Clara said in her mind. 'Who the hell are you? How am I in here?'
'All these questions! Maybe you need a Doctor,' the other Clara replied.
'Who are you?' Clara repeated, her voice more louder and demanding.
'Clara, Clara, Clara. Pay attention, Clara! Cyber Planner, of course. Now, where's your precious Doctor? How are you going to break it to him that the Cyberiad are taking over your brain?' the other Clara grinned. The metal on the side of the Cyber Planner's face was flashing.
Clara pulled herself into reality and outside of her mind, then turned and saw the Doctor running in. The panic and concern on his face made her want to cry. As she went to say something, she realised she couldn't talk, and that she was saying something she didn't want to say. She didn't even know she had said it.
'Hey, Doctor, glad you could make it,' she'd said. The Doctor frowned, pulling his sonic from his jacket.
'Clara? What's that on your face?' he asked softly. Clara's mouth went dry, but she could finally speak now.
'I...' she felt a twitching sense in the back of her head. 'Something is in my head.' The Doctor soniced her, and his eyes seemed to droop with a sudden dread.
'Clara... I'm so sorry. The Cyberiad are taking you over,' he whispered, ghastly. Then, his eyes went from droopy to ablaze and he began shouting.
'Let Clara go! Have me instead! Why do you want her? I have information on Time Lords! Time travel! Everything! Why do you want her?' he started yelling at Clara. Clara tried to ask him to stop, but she couldn't. She wasn't sure if it was the Cyber Planner stopping her or the anxiety and fear spreading through her.
'I'm impossible, aren't I? Oh, Doctor, aren't you getting a bit of a sour throat? Maybe you should run along back to your blue box whilst me and Clara have a small debate on something. Don't worry, shouldn't be long!' she found herself saying. The Doctor just stared at her.
