On Thursday afternoon Clara was standing at the back of the class listening to the kids read aloud 'To Kill A Mockingbird' a paragraph at a time. The last bell rang and they all rushed out, eager to get home. The Doctor hadn't turned up since Monday.

"Have a nice evening, everyone!" she said at the empty classroom.

She gazed out of the window and saw Emily sat against the wall at the edge of the car park, smoking a cigarette and looking at her phone.

Clara's phone buzzed in her pocket, she took it out to see Emily ringing her.

"Hello," Clara said, smiling to herself.

"I can see you, you know," Emily laughed. "And I like what you are wearing..."

Clara opened the window and leaned out slightly, "is that better?" she said to Emily.

"I'm imagining that top displays cleavage," said Emily, "I may need a closer inspection." She laughed.

"I would say you are right," Clara looked down at herself, undoing the zip on her white blouse slightly.

"So when will you be finished? I see... children leaving," said Emily, "looks like your work is done."

"I wish it was as simple as that," Clara sighed, "give me ten minutes. I presume you will be wanting a lift?"

Emily held up the helmet. "No, of course not," she said sarcastically. "I'm just sat here for no reason whatsoever."

"I'll be out shortly," Clara laughed, closing the window. "Please don't talk to anyone today, ok?"

"I'll try not to," Emily laughed.

Clara collected her things and tidied up, smiling to herself. She went to leave by the door, pulling on her black leather trench coat on the way.

She locked the door of her classroom and turned round to immediately found herself in the doorway of the TARDIS as she tripped up the step.

"Oh hello Clara, there you are!" said the Doctor brightly.

Clara turned around to see the TARDIS completely covering the door to her classroom, the only way to leave the room was through the windows. She sighed to herself.

"Hello Doctor," said Clara.

"Glad I've run into you-"

"Doesn't look like I had a choice," said Clara looking around her.

"That blue planet is waiting Clara, all the wonders of the universe..." he walked over, shutting the doors behind her.

"I actually am busy tonight," said Clara, "I don't suppose that matters?"

"And after your frankly Houdiniesque escapades earlier-"

"On Monday," Clara corrected. "It's now Thursday."

"Not important, come on, let's go and explore a planet! A nebula! Or a underwater forest!"

"Do we have to go right now?" Clara said, sighing.

"Yes we do, let's have an adventure!" he held out his hands.

"And the fact I have plans?"

"Put them on hold," he pointed at the TARDIS console, "I'll drop you back in five minutes."

"Promise?"

"I promise. On," he pointed at his chest, "both my hearts" He grinned at her.

Clara folded her arms, saying nothing before shaking her head. "I really do have something very important to do."

"I'll drop you back in time for school tomorrow?"

"No," Clara said."I need to stay here now."

"If you say so," said the Doctor.

"Are you not upset with me?" she asked, approaching him.

"I'm not upset with you," he said, turning away.

"Ok then," Clara nodded. "I can't help it, ok? Sometimes when you meet someone there's some sort of thing that happens inside you that makes you only want to be with them-"

"Afraid not,," the Doctor shook his head, "It's a chemical called seratonin."

"Oh," said Clara, deflated.

"And you are giving it off in spades!" the Doctor said, strolling away from her. "Wow!"

"Can't you just let me see her?" said Clara, pleading. "Please? I've been looking forward to this for the last three days, come on," said Clara.

"By the way, I do know what's happening," he said, "you didn't have to get the flatmate to tell me," he inspected the console. "Except for the mystery... of the scissors."

"What?" said Clara, confused.

"The flatmate told me you use scissors on each other, that cannot be safe..."

"I don't..." she trailed off, blushing. "Oh dear god, please do not ever ever say that to me again."

"So what do you do with them?" He looked at her, curious.

"I am not having this conversation with you," Clara said turning away, needing to put him off, "we do not use scissors on each other. He was wrong."

"Oh, ok then," he said, "I'm glad about that!"

"Me too... Look I'm sorry, ok?" Clara said. "What can I say, it's addicting, ok?"

"Wrong... again," said the Doctor, "that's dopamine, some little part of your brain telling you you want something, and you won't stop until you get it. You've got decreased sleep, increased energy," he looked her up and down, "a subtle change in dress sense, more makeup, mild palpatations, wide eyes... I bet you're going to tell me it's all new and exciting! You can't stand to be apart from her for more than a minute."

"Well... yes," agreed Clara, blushing. "I am all those things... Is that so wrong?"

"Of course it's not, the human race has made itself on those feelings, actually isn't there a film? Paris is a city of it, Venice is full of pictures of it, and a few canals, there is a shack of it next to a baby... who's that woman who sings about never ever ever ever ever getting back together?"

"Taylor Swift?" Clara offered.

"Yes her!" he exclaimed before adding, "she made a living out of it," he lowered his voice, "she gets royalties until the end of time with that one..."

"What's your point?" Clara sighed.

"My point?" said the Doctor. "Oh I don't have one, just wanted to impress you with my knowledge of science, geography and contemporary pop music. I'm in training for the Trivial Pursuit championship-" he began smiling.

"Doctor!" said Clara.

"So, a blue planet?" said the Doctor. "That sounds fun doesn't it?"

"Can you just pick me up tomorrow?" Clara said. "Let me out and just come back at this time tomorrow. This exact place and time, just... tomorrow."

"I'm not just someone you can reschedule," said the Doctor.

"All it would take is for me to leave and you flip that switch and in thirty seconds you can just pick me up tomorrow," she said, appealing to him. "If you take me now I'm going to be distracted... and it's going to be the only thing I talk about the whole way round..."

The Doctor grimaced. "Do you have plans to see Bitey tomorrow?"

"No, she's working. I have work drinks which I am unsurprisingly very keen to avoid. Tomorrow you can take me anywhere you want. I am all yours."

"You? Avoiding drinks? ... Anywhere?" said the Doctor.

"Just today, you need to let me go... OK?" Clara folded her arms and aimed her best gaze at the Doctor.

"Love changes everything," he paused, looking at her, confused.

"No it doesn't," said Clara, before saying, "hang on, my mum had that, I know this one... Michael..."

The Doctor lifted his eyebrows.

"I want to say B... Ba... is it Bolton or Ball?"

"Go on," the Doctor said, smiling.

"Michael... Bolton?"

The Doctor shook his head. "And I had such high hopes for you on the team. So tomorrow... Is that a date?" he asked.

"Yes," she said, smiling, opening the door, "4th March." She opened it to find her classroom door locked in front. On a second inspection there was just enough room for her to squeeze past the TARDIS into the corridor. It disappeared into thin air behind her as she hurried out.
