"Yes, I will tell the Doctor!" Clara resounded.

"Not even keep it a secret for a few hours?"

"No. He has to know".

"Not really. Wait, you don't care if the Doctor knows, you just want me out of here".

"Right. You stop your accusing and listen for once". It was probably the first time Clara had actually caught Missy by surprise. She actually had control of the situation and Missy knew she would revel in it, finally being able to catch her tongue. "What about a deal?"

"A deal?" Missy skulked around her, circling her like a predator. Curiosity had crept to her face and Clara had spotted it. "Usually I make the deals, little one". Clara ignored the obvious attempt to patronise and put her off.

"My silence for you to go off to some planet and never come back".

"And the Nethersphere".

"Is to be dropped at the nearest UNIT building and to be locked in the Black Archive".

"Yah, yah, I'm gonna fall for that", she scoffed, her Scottish accent bleeding into every word. "So, everyone inside is going to stay there, are they?"

"Yes".

"Really, so no dead boyfriends or favours for the Doctor?"

"No. They will stay in there. For good".

"Well, that's no fair. I've got people in there. In fact, let me take control dear". She sat Clara down on the step, pushed her brunette hair behind her ear and threw the bag of jellybabies at her. "I mean it IS your first time". Clara stayed silent, knowing she couldn't take Missy on. Though she wanted to. She wanted to be the one to take Missy under her arm and send her flying through the vacuum of space. The Doctor had teased her just after the incident with the Daleks at their 'Misflémance', and it was the most annoying month of her life.

"This is the deal. I will release all of the minds caught in the Nethersphere, you don't say a word to the Doctor and I'll stay here for a couple more months at least".

"Why do you even want to stay here?" she asked while diving her hand into the jellybaby bag, pulling out the decapitated red one and screwing a face. She chucked it back in and passed the bag back to Missy.

"I want to find Gallifrey. I want to show Ashildr the place where she was born and I want to have a home again". Clara sighed heavily and got up.

"The Doctor's the only one that can unlock it, isn't he?" she whispered and started to clomp up the stairs. She stared longingly at the red lights dancing beside Missy and smiled. "Okay. Deal".

"So then, Theta, where now?"

"Well, firstly, you're going to stop calling me Theta. And then we're going to go back to the console room, check on your mum".

"Fine, I'll drop the Theta. On the condition that I can keep the books", she bellowed pointing to the books held steadily in her arms.

"What books even are they?" he asked, picking the first off the top. It was a thick leather bound novel, covered in what looked like crocodile skin dyed red. There were tiny rips in the top and there was a circular Gallifreyan stamp near the bottom right. In gold there was a foreign word that even the TARDIS couldn't translate.

"Ahh, yes. 'Die Vlamme Van Die Vergete', The Flames of the Forgotten. A great book, your mother's favourite. That's the first one ever published". He passed it back, putting it back on her pile and heading back down the corridor, poking his head around Donna's door to make sure she was alright. To his surprise, the light was on and Donna was sitting on the floor with a whole load of wires and electronics in front of her. She was frantically trying to force two wires together, but with no luck. Looking around for anyone watching her, she grabbed a welding iron from behind her and started to link them together, without much success. She had missed the cable at least four times and stabbed herself in the finger. The Doctor chuckled to himself from the door, and felt a bit like a father watching his child try to figure something out for the first time.

"Ah, Donna. You stole my mind, but even the greatest mind in the universe couldn't replace your impeccably bad DIY skills", he thought to himself. Eventually she threw the iron away in a huff, and then looked deep in thought. Squeezing her hands into tight fists, she concentrated on her fingertips and watched as an orange energy ran into them. She grabbed the wires and watched as they melted together under the heat of her hands.

"What do you think Doctor?" she asked, still staring in amazement at the bonded cables.

"I think that you've wasted a lot of regeneration energy on a tiny project".

"But I don't need it, do I? I'm immortal. I don't need to regenerate. And plus, you really should be thanking me, this 'tiny project' increases the speed of your navigation monitor by up to twenty seven point five percent".

"Come on. Either get back to bed or stop tearing my ship apart".

"Can I explore? Please".

"What?"

"Can I explore? I'm so booooored! I've counted the number of dimples on the ceiling, worked out my own formula for counting the number of dimples on the ceiling, made the bed sixty four times, made four copies of the picture on the wall and counted the number of hairs on my head. It's killing me Doctor. And I can't die. Just, please. I'll stay in the library, and I'll scream if I think I'm about to blow up".

"Fine. But stay in the library. And don't read the Time War Chronicles. Don't need another one of you asking questions".
