Clara woke up to a thumping headache permeating her right temple. She cautiously opened her left eye to find herself in bed in her room in the TARDIS. She couldn't remember falling asleep or even going to her bedroom. She looked down her body to realise she was fully dressed.

She stirred, stretching her arms out before rubbing her forehead to ease the pain away. Padding around the room went towards the door to investigate how she had ended up in the bedroom without realising it. The last thing she remembered was being with the Doctor. She checked her phone, it was switched off.

She pressed the button to open the door into the corridor. It swooshed as normal, but instead of revealing the clean, cool white surroundings she was expecting it opened onto a solid grey concrete breeze block wall. Clara ran her hand across the bricks to check she wasn't imagining it.

"Oh no, no, no!" she shouted loudly, banging both her fists against the exposed brickwork until they hurt, immediately realising what was happening. "Why is it always me?!" She banged her forehead onto the cool wall a couple of times.

A light tapping sounded behind her, causing Clara to spin around to find the source of the noise.

"Ahh yes," a familiar voice filled the air. "You are awake. Is that sound you or the wall?"

"Bonnie," Clara said resignedly, narrowing her eyes. A large oblong picture frame above the dressing table to her right displayed Bonnie, dressed in her clothes, knocking her right knuckle on the surface of the glass.

"Clara Oswald, love of my human life, we meet again," Bonnie raised an eyebrow.

"Why do you always go after me?" Clara asked.

"Because I very much enjoy being you Clara," Bonnie smirked. "And your close proximity to the Doctor makes you a very suitable target."

Clara sat on the bed opposite the photo frame, folding her arms, annoyed. "What do you want this time?"

"So here is what we are going to do, we can do this the easy way or the hard way. You will tell me how to drive the TARDIS," Bonnie said unblinking.

"Err... No I will not," Clara answered abruptly. "How did you even get in here?"

"The Doctor-" Bonnie started.

"What have you done to the Doctor?" Clara interrupted, standing up.

"The Doctor is also refusing to give us any information," Bonnie continued, "so we have had to move on to the only other person who knows how the TARDIS works." She paused. "You."

"And you should know by now I am not going to tell you anything," Clara said sternly.

"It looks like we are going to have to do this the hard way then," Bonnie reflected, closing her eyes as if recalling an old piece of information.

"What are you doing-" Clara started before immediately feeling a deep searing pain inside the centre of her brain, enough to cause her to lose her balance and fall to the floor.

Clara screamed out in agony, clutching at her head. She tried to reflect the pain back towards Bonnie. "You've done this before, it does... not... work."

Bonnie fell away from the screen after a few minutes. She reappeared to scowl at Clara before the picture frame went completely black.

"Oww," Clara said, picking herself off the floor as the pain melted away. "That never gets any easier." She tried to think quickly what to do next, knowing that Bonnie would be back.

Clara scrambled to reach her phone and turn it on. The iPhone blinked to life, revealing there was 2% battery left. Enough for one message.

She pulled up Emily's number and typed out a short message.

: Help me. Please save me.

The phone bleeped to indicate it had 1% battery left as she sent the message. It got a small green tick next to it as Clara exhaled with a small sigh of relief.

She waited ten minutes for a reply, seeing a response briefly flash up on the home screen before the handset silently died with the sound of no power.

Clara let out a frustrated groan, tossing the handset onto the bed sheets next to her and laying on her back. She remained still for a few minutes, trying to figure out a new plan.

"Clara!" Bonnie shouted into the air, tapping on the picture frame again. "Please explain this to me. I have just received this message." Bonnie cleared her throat. "Well I did try to get you an afternoon off. What's he doing? Still being a..." Bonnie paused for a moment, "a fucking prick?"

Clara let out a short laugh in response, raising herself to sit up on the edge of the mattress.

"Why is your pathetic little girlfriend sending expletive messages to this phone?" Bonnie snarled directly at Clara after looking at the handset. "Have you managed to get something out?"

Clara folded her arms, saying nothing, only raising her eyebrows and pursing her lips.

"Tell me!" Bonnie demanded. "Or I will-"

"Or you'll what?" Clara remained still. "We've established I can throw back anything you do."

"Maybe it's time we get her in here," Bonnie said with a glint in her eye, "I have a very comfortable pod waiting for her, right next to yours... or..." she paused, scrolling through the messages on the phone. "This is very... graphic," Bonnie grinned as she read, "you humans never cease to amaze me. Such complex vocabulary. Of course, I only have your memories to go by, but maybe... I'll see what all the fuss is about."

"Don't you fucking dare!" Clara shouted, immediately getting up from the bed. "If you lay one finger on her I will kill you without a second thought," she pointed at Bonnie's image on the picture. "Hurt me, fine, but this is nothing to do with her. You leave Emily alone."

"Ahh," Bonnie smirked, "it appears I have found your weakness. The... pathetic... little... girlfriend."

"Do not talk about her like that," Clara snapped.

"Tell me how to work the TARDIS," Bonnie demanded.

"No," Clara said, shaking her head, rage pumping through her veins.

"Well then," Bonnie smirked back, holding up the phone with Emily's contact number. "Let's invite her over." She pressed the green phone symbol and held it to her right ear. "I can use her as leverage."

"Don't do this," Clara warned, "if you do anything -"

"Shh... Looks like she doesn't want to speak to you," Bonnie smirked, holding up the screen so Clara could see. "Oh dear, shame, looks like I'm going to have to get someone to get her-"

"Hi," came a tinny voice from the speaker. Bonnie pressed the loudspeaker button.

"Emily!" Clara shouted, "Emily! Help me! Emily!"

Bonnie covered the microphone with her right hand. "She can't hear you, you know," Bonnie hissed, "so please be quiet, I'm trying to concentrate on having a meaningful conversation here."

Clara hung her head, holding the bridge of her nose.

"Hello," Bonnie said brightly.

"Err," Clara reflected, "I don't speak like that, she is going to know that is not me."

"How are your time crystals or whatever the fuck the Doctor needed you to go and do?" Emily replied through the phone.

"Oh that," Bonnie laughed falsely, "turns out that thing I had to do isn't a thing now so I can do something with you." Bonnie grinned at Clara.

"I really do not speak like that!" Clara fumed.

"OK," Emily said, pausing.

Clara smiled to herself. "She can tell, you know. That pause is her being unsure. She knows you're not me."

"Look it's fine, we can meet up later. The Doctor clearly wants your attention-"

"The Doctor," Bonnie interrupted, "is a bit of an arse and kind of... ummm... indisposed at the moment. Fixing something on the first floor I think."

"A bit of an arse?" Clara scoffed.

"It's cool," Emily replied blankly, "do what you need to do, I'm still at Markston's."

"Will I see you later?" Bonnie asked.

"Depends," Emily replied.

"On what?"

"If the Doctor is still hanging around," Emily said, slightly annoyed.

"The Doctor will not be here," Bonnie laughed. "You do not need to worry about him."

"So I won't have to blackmail my way in like I did last night?" Emily asked. "I won't have to get the Doctor to profess his undying love for you to get directions?"

"Hopefully not," Bonnie said, a maniacal grin appearing. "If you want to smuggle some drinks in again, though, that would be greatly appreciated."

Emily laughed once. "Deal."

"Good," Clara replied. "I am... looking forward to it."

"I should go," Emily sighed, "I probably have a video of a cat getting trapped in a fridge door or something to watch."

"I love videos of cats!" Bonnie exclaimed before laughing quietly.

"This is ridiculous," Clara sighed under her breath, "I do not speak like this!"

"I am very jealous." Bonnie smirked at Clara.

"See you later," Emily said.

"Bye!" Bonnie exclaimed. She ended the call.

"She will know that is not me, you know," Clara reiterated.

"Well," Bonnie replaced the handset into the back pocket of her trousers off camera, "looks like I have discovered the Doctor's weakness and I have a date tonight-"

"You certainly do not have a date tonight," Clara snapped loudly, "not even I have had a proper date with her! We're not even... dating!"

"Your physical activities over the last few weeks would say otherwise," Bonnie replied, "it gets very lonely pretending to be Petronella, you know. All that science, the white coats and those glasses and having to fake having asthma... very exhausting."

"Find someone else," Clara pleaded. "There are seven billion other people out there. Choose another one. If you are trying pass off being human you are really going the wrong way about it."

"You seem to be oddly concerned about someone who means nothing to you," Bonnie said in a surprisingly compassionate tone.

"Bonnie," Clara groaned, "I swear to if you do anything... anything to her, I will not be responsible for my actions." She glared directly into Bonnie's eyes.

Bonnie stared back through the picture frame for thirty seconds. A loud repetative thumping noise off camera broke her concentration. She laughed once, creasing her eyebrows, "what are they doing? They appear to be trying to... push the TARDIS over. Why are they doing that?"

"They're students," Clara offered up as a reason, sighing inwardly as she nodded.

"I thought better of you Clara," Bonnie said, disheartened. "I thought you have better taste than this... Emily."

"Don't even mention her name," Clara warned. "Leave her alone."

"They appear to have now got in somehow... how have they done that?"

"I don't know," Clara replied.

"Tell me!" Bonnie barked.

"No," Clara shrugged, "I actually have no idea." She tried to figure out a reason, coming up with nothing.

"Looks like my date has arrived for the evening with her suitably inebriated friends," Bonnie paused, adding sarcastically, "how delightful. Try not to go anywhere, I may or may not be back later. Depends whether I put you girlfriend out of the misery of seeing you or not." She laughed loudly.

"Bonnie, no!" Clara shouted as Bonnie disappeared off the screen. "No!" she banged the wall next to the picture frame with her right fist. "The assembled hoards of Genghis Khan can't get in," Clara folded her arms, rolling her eyes, "but four drunk students can? For god's sake."
