"How'd I look?" Missy asked, wandering into the console room. She had changed from her usual Victorian skirt and shirt ensemble into a more battle-ready attire. Her pinned back brunette hair was loose, flowing down her shoulders, and she was wearing a black and purple catsuit. Around her waist was a leather belt with ammunition pockets, and she wore tall heeled boots. In her hand was her blaster, freshly polished so it gave off a burnished glow under the light.

"Stunning. Like a queen", The Doctor answered. He himself had decided not to change his look in the wake of his change of sides, instead he had dug out an old maroon velvet jacket. He felt it made him look powerful and intense, but his wild untamed curls of hair went slightly against that idea. The sceptre sat comfortably in his hand and was now completely under his control now that he had telepathically connected to it. All he had to do was think and it would happen.

"Come. Let's make our entrance a big one", he said to Missy, gesturing her over to one side of the console.

"How?"

"Ah, my sweetie pie. Rule 203 of the Doctor: don't reveal your plan until the last minute". Missy had to be content with this answer, but did peer over his shoulder at some plans that had been spread across the room.

"So can you give me an idea about what it's about?" she lilted.

"The sceptre doesn't just destroy. It moves matter too". He obviously wasn't going to tell anymore, but it didn't mean that she couldn't go looking for the answers. She sighed as she found it in the back of his mind someone.

"You want to replace Earth with Gallifrey, don't you? You can't find it, so you're bringing it here".

"Yes, and stop looking in my mind would you? I haven't tidied yet, it's like having uninvited guests", he said, still studying the papers. They had been covered in small writing, some Gallifreyan, others Latin, even a little English in places.

"You can keep asking me Doctor, but your uninvited guest". She pointed to herself. "Ain't leaving".

"Maybe so", he murmured. "Yes, yes. I want to bring back Gallifrey. I want to keep it safe".

"Why'd you have to destroy the humans though? They could be... useful".

"Humans and Time Lords will never live in peace. The Time Lords will want to rebuild Gallifrey on Earth. And to rebuild means to take down".

"You do know your whole life sort of goes against that sentence". The Doctor huffed frustrated and stormed away from her. "Fine. Fine. Do it Doctor. But remember Rose. Martha, Donna, Amy, Clara"

"Clara's dead", he said, hiding in the darkness underneath the console. "Rose is dead, Martha's dead, Donna's dead, Amy's dead. They all are".

"They aren't though. I mean Martha's in UNIT, Rose is living with you in a different universe, Donna's happy, and Amy, well she may be dead now, but she lived a life. A good one too". The Doctor came back up the steps and looked at her mournfully. "But you don't think that, do you? You think they're dead to make it easier".

"Let's get back to work. Now the sceptre needs enough Artron energy to-"

"So if I left now, if I walked out that door, would you think that I was dead?"

"If we powered it by the TARDIS, there's a risk that we may de-"

"I mean seriously like dead, dead. Never coming back dead. You'd think that?"

"And the stone is a power source of its own so maybe we can-"

"So I'd be dead to you if I walked right out that -"

"Just shut up!"

"Door", Missy finished, looking like a scolded child.

"You want to know the truth? Yes. Yes! I'd think you were dead. Just so I can get on with my life. So that I didn't have the burden of your memory. So there!" Missy looked absolutely disgusted at her friend, looking him up and down like he was made out of something horrible.

"So I'm just a stepping stone? Your stepping stone to use up then leave when you find something better?" The Doctor gave a merciless nod. Missy sarcastically smiled and started to walk towards the door. "And there's me thinking that all those years of me helping you in the academy, and loving you actually counted to something".

"Don't leave Koschei", he said catching her hand. She spun back towards him, shoving his hand away with a piercing glare. "I need you".

"Don't call me Koschei. You don't have the right anymore. And you don't need me. You just want your victory. For everyone on Gallifrey to see you as a hero". She leant on the door frame, looking back at his depressed figure. "Don't follow me Doctor. I don't want to burden you with my memory".
