Clara blinked. She was laid on the floor of the TARDIS, which was odd. She could've sworn that she was in the staff room at school, marking some of year nine's work, as she usually did in her free period on a Monday. She sat up shakily.
The Doctor stood by the console, tinkering with this and that, when he heard Clara moving.

"Oh, you're awake," he said in surprise. Clara stood up, frowning confusedly.

"Doctor?" she said. "What happened?" The Doctor shook his head slowly.
"I'm... not really sure to be quite honest. Thought maybe it was something you'd done," he shrugged, turning back to the console. Clara walked to stand next him at the console and crossed her arms.

"What, so it's just a coincidence that I happen to have mysteriously woken up in the TARDIS? With no recollection of what's happened, might I add," she said . The Doctor blinked at her and raised his eyebrows.
"Well... it is a little odd I must say. Maybe the TARDIS is faulty," he muttered, glancing up at the top of the console. "You okay old girl?"
The TARDIS made a soft hum in response and he looked back at Clara in confusion.
"She seems okay." Clara raised her (admittedly less impressive) eyebrows back at him.

"She seems okay? What about me? I just passed out and woke up in your time machine! Surely that's cause for concern?" The Doctor took out his sonic screwdriver with a sigh.
"You're worrying too much, Clara," he said quietly, rolling her name on his tongue. He scanned her with the screwdriver and then hummed thoughtfully.

Clara shook her head.

"No, Doctor, I think I'm worrying just about the right amount. I think you, on the other hand, seem suspiciously calm. What's really going on?" The Doctor began walking around the console, trying not to look like he was keeping his distance from her. An angry Clara was not a fun Clara.
"I'm not being suspiciously calm," he said defensively. "But I may worry a little more now... have you possibly eaten anything... for loss of a better word 'alien' recently?" he said from the other side of the console. Clara followed him around the console.

"When would I have eaten anything alien? I mean apart from when I'm with you? And what do you mean you're worried now? What did the screwdriver say?" She cringed a little at the phrase "what did the screwdriver say?" but stared him out regardless. The Doctor grimaced.
"Well... it's like something I've seen before so that's good. Somehow you've gotten these sort of particles inside of you. The type I've encountered before were called Huon particles. My friend Donna was dosed with them," he rambled. He noticed Clara's slightly worried expression

"They're not dangerous!"

"Well what are they then?" she asked. "What are they doing... in me?"

The Doctor skimmed past Clara.
You're asking a lot of questions... think of them like a magnet, pulling you somewhere. We just need to find where that 'somewhere' is. The TARDIS obviously brought you here to let me help you," he mumbled, walking up the stairs to his bookshelves.

Clara followed him up the stairs.
"Well how did they get there? And of course I'm asking a lot of questions, Doctor, I've turned into a giant magnet!" She knew as soon as she said it that he was going to say something to correct her, so she gave him a look that said 'don't you dare'. She was NOT in the mood

The Doctor opened his mouth but closed it as soon as he saw her expression.
"I don't know... that's why I asked if you've eaten anything. My friend Donna had it in her coffee, but it normally takes a good few months to make a difference," he hummed, scanning through a handful of books. "I'll fix it."

Clara nodded.
"Good," she said. "So... What am I supposed to do in the meantime? Just sit around here and hope I don't get transported anywhere else?"

The Doctor nodded.
"Yes, exactly. You've caught on very quickly," he smirked, almost patting her head but refraining from fear of losing his hand. He passed her a pile of books instead.
"You could always help by reading through these," he said, adding another book to the already hefty pile, causing Clara's face to disappear from view.

Clara shifted under the weight of the books and leaned around them to see the Doctor.
"Right. Very helpful. I'll just save myself shall I? And in the meantime I suppose the ghost of teachers past will mark year nine's English homework."

The Doctor rolled his eyes, making sure he was facing away from her.
"I'm going to help you by reading these," he hissed, nodding to another large pile. "And we're in a time machine, Clara, the English homework is not urgent."
Clara plonked the books down on the floor and sat down next to them.
"Fine," she sighed. "But I-" And then she was gone.

The Doctor spun around and stared at the space where Clara had just stood.
"Clara?" He called, gliding down the stairs and circling the console room.
"Clara?!" He halted, his hands clutching the console.
"I'll find you," he growled, getting his screwdriver out and setting to work.
