I have Twelve/Missy feels. This was born. I'm guessing it will be around 5 chapters. I am notoriously terrible at sticking to short story plans and finishing things though, so we'll see how it goes. Reviews are always appreciated.

Disclaimer: I don't own Doctor Who or any of the characters. I do, however, own a talking dalek toy which does not appear in this story.

Chapter One

The Doctor picks up the TARDIS phone cautiously, pausing for a moment before speaking.

"Hello?"

"Hello," a robotic voice responds. "This is an automated message service. Your presence is requested at the coordinates 747 00 00 86B by 71. Thank you, and have a good day..." the voice pauses for a moment, "Doctor."

The line goes dead.

The voice is familiar, almost mocking, the Doctor thinks as his mind instantly calculates 543 ways this could be a trap. He's a smart man. He knows he shouldn't go charging blindly into situations like this, alone and vulnerable, but he pauses for barely a millisecond before punching the coordinates in and setting the TARDIS in motion. He's never been one to resist curiosity.

Meanwhile, on the other end of the line, a woman hangs up the phone and laughs gleefully. Today is going to be a good day, she thinks to herself, spinning around to set the plan in motion.

...

As the whirring comes to a stop and the TARDIS lands, the Doctor checks the screen to discern where he is. The screen shows a rich blue pebbled ground that meets a gently lapping purple ocean. The bottom of the screen states that the planet's name is Locomosolarem, a planet infamous for its ability to constantly change locations. It was a mystery to all how it occurred. One day it would be floating around, fifth planet from the centre of the solar system known as B-52 and the next thing you knew it would be off somewhere in the Andromeda galaxy.

The Doctor visited this planet once when he was much younger, a past regeneration long since gone, but he has never been able to find it since. He is willing to bet that the invitation did not come from the locals (he's had a bit of a strained relationship with the Locomosolarites ever since he accidently, and successfully, proposed to – and very nearly married – the woman who was supposed to marry the King of Locomosolarem).

He has a feeling he knows who called him and gave him the coordinates. If he is right, it will be bad, very bad, for the people of Locomosolarem; he will be in for a busy day. But he can't help hoping that maybe, just maybe, it is her that has led him here.

The Doctor steps out of his TARDIS, breathing the savoury air into his lungs. The beach is empty, a sharp contrast to the last time he visited this planet when it had been alive in a flurry of people, the sounds of laughter and voices filling the air. This time it is silent, silent apart from the voice in his head that implores him to turn to the right. He turns.

There she sits, perched upon a rock, one leg crossed over the other and her umbrella resting against the rock. The Master. The Mistress. Missy. Back again.

"Well don't just stand there gaping at me" she says as she jumps up and glides over to him.

The Doctor stands frozen in place. Part of him knows that he should get back into the TARDIS and fly away, but another part of him knows that with Missy here the planet is in serious danger.

"Aren't you glad to see me?" Missy asks, pouting and reaching out to let a finger gently glide across his cheek.

He doesn't even bother asking or stating the obvious. The Master cheating death is nothing new to him. He has more important questions to ask like 'What have you done to the planet?', 'What are you planning?' and 'Why are you so close to me, playing with my hair and looking at me like that?'.

He voices none of these questions, instead choosing to step back out of her reach and grasp his sonic screwdriver in his pocket, feeling like he has to get a grip on something, anything.

"Come on," Missy says, stepping backwards from him towards a tree lined path. "I've reserved the honeymoon suite. Well, they call it the honeymoon suite. It hasn't been used for that since the scandal during the reign of the 54th king, but of course you know all about that, don't you, Doctor."

She winks. The Doctor splutters, not able to find any actual words. She smiles.

He follows the female Time Lord down the path. She leads the way ahead of him, a skip in her step as she prances in diagonal lines along the path, touching leaves and flowers as she passes. The Doctor walks behind her, solemn, steady, fighting as he tries to hide that small smile that wants to break out on his face at Missy's frolicking.

It doesn't take long for them to reach their destination, a large oval building overlooking the purple sea with the words 'Royal Honeymoon Suite' written in the local language above the doorway. The Doctor stops just before the doorway, grabbing Missy's arm and gently pulling her to a stop.

"Where are all the people?" he says, finally asking what he's been dying to know since he set foot outside his TARDIS.

He knows she is behind it.

Missy holds her finger up to her lips.

"Shh. Don't want to spoil the surprise."

Her face lights up with her cheeky grin as she spins back around and walks into the building. The Doctor follows again. They walk through a couple of hallways before stepping in a waiting elevator that will take them to the second floor. The second the elevator doors close Missy turns to face him, her eyes hungry and greedy. She nips her teeth at him. The Doctor finds himself pushing his body back into the corner of the elevator as much as physically possible. He's not quite sure why, he's not scared of her exactly, but he's confused and he doesn't know what to do with himself. Maybe he should just kiss her again. Missy leans forward, already close to him in the confined space. She presses her lips together, barely able to contain her excitement. She'll be able to share it with him soon.

The elevator doors open with a ding. They step out of the lift, the Doctor still keeping his distance from Missy, though he needn't have tried so hard. Missy twirls around and around, arms opened wide, as they enter what the Doctor remembers to have been the bedroom of the Royal Honeymoon Suite. The room is filled with screens and machines, many of which the Doctor recognises as Time Lord technology.

The spinning Time Lord comes to a stop facing the Doctor, opening her arms wide as if showing off what she's done.

"Ta da!"

"What is this?"

"Oh," she says, her voice falling. "Did I disappoint you. When I said honeymoon, did you really think... oh."

Her face dons a fake pout. The Doctor frowns, ignoring her last comment, and leans over one of the screens. It, like most of the others, shows security footage of the native people of the planet, all standing anxiously in lines.

"Well there's always later," she throws out there casually.

"What have you done?" he asks accusingly, still focused on the screens.

Missy tilts her head to the side with faux shame.

"Well, I might've told a teensy mistruth." She holds her fingers millimetres apart, illustrating just how small the lie was in her opinion.

"Missy," the Doctor growls as she continues to play coy.

Her eyes twinkle, saying 'watch me'. She leans down over the machines and presses a button. She can feel the weight of his eyes on her body.

"Hello, citizens of Locomosolarem. This is your Mistress speaking." She turns to face the Doctor, silently giggling. He isn't amused. She speaks in a pleasing and light voice, like tinkling bells. She's clearly enjoying herself. "Please continue to evacuate in a calm and orderly fashion. Remember no harm will come to you if you follow instructions."

She takes her finger off the button, ending the broadcast and turns back to face the Doctor. Her voice takes on a harsher and more Scottish tone. "Well that's not strictly true."

"What are you doing to them? Where are you sending them?" the Doctor asks.

"Oh, nothing too horrible. Just sending them through a portal away from this planet." She brushes off his concern with a flick of her hand, turning back to the screens and pressing some buttons.

"Where does the portal lead?"

"A black hole? A wormhole? The centre of a star?" she guesses haphazardly. "I'm sure it will be a fun surprise for them."

"Why are they evacuating?"

"Now this is where it gets good." She claps her hands together and giggles. "Because I told them to, came up with some story about radiation and the entire planet becoming unsafe."

"Why?"

"I need the planet."

"Why?"

"For you. For us."

The Doctor looks taken aback, though realistically nothing that this Time Lord does should shock him.

"Surprise," Missy says cheekily. "Our very own planet. You can be king and I'll be queen. Just us in our own world."

For some reason, the Doctor doesn't seem to see eye to eye with Missy on this. He isn't so keen on having his own conquered planet to rule while the corpses of the former inhabitants float through space.

"I will stop you," he vows, his eyebrows shifting into attack mode.

"Oh, I thought you might say that," she says, faking sadness but leaving neither of them with any doubt that she has always known what he is going to do. "You see the only way to stop me is to go down to the portal and shut it down, but, oh, that would have to be done in the next fifteen minutes before it's too late."

The Doctor says nothing, doing as predicted and running straight out of the room. It's time to save another planet.

"Be safe," Missy calls mockingly as he leaves. "Hurry back, love."

...

Missy watches as the Doctor makes his way into the large warehouse where the portal is located. She smiles to herself as she watches him run through the corridors, slowing down each time he reaches a door to check if the controls are in there. He needn't have. She's made it easy for him. When she conquered the planet (although admittedly not so much 'conquered' as turn up unnoticed and casually slip into a position of power, using her skills and wit to become their leader, their Mistress – but conquered sounds much better) she had ordered the portal warehouse to be built with the Gallifreyan words for 'control room' on the door to the room itself, a small nod to him and their Gallifreyan roots. She could not have made it easier for him if she'd drawn him a map.

The Doctor looks up towards the camera he knows is there once he sees the writing on the door. If he hadn't already known that Missy set this up just for him, just to get his attention and hold it for what would be only a tiny spec of his life, he knows it now. Missy smiles and leans forward towards the screen, her eyes focused solely on the image of the Doctor as he fiddles with the controls, trying to find a way to foil her plan. There is a way, of course, and it isn't an oversight. She's purposefully left holes in her plan, knowing that the Doctor, and only the Doctor, will be able to find them and slip through. That in itself is all part of her plan.

The Doctor talks to himself as he works. Missy wonders if he even realises he's doing it. She hears him talk apparent nonsense and speak to past companions who aren't even there. "Clara, hold down that lever for me." "Ace, mind the blue cables, they bite."

What Missy sees in front of her is a lonely man, driven to madness. She recognises it. She feels it too.

Missy talks to herself as well, although this time her words are more of a running commentary on the Doctor's adventures. "Oh!" "Oh, you clever, clever man." "Come on, Doctor, you're too smart to fall for that... Good." "That's my boy."

She can pinpoint the exact moment when he figures out exactly what he has to do to save the inhabitants of the planet. He jumps up, exclaiming "hah!"

She smiles, proud in a way.

It's at this point that Missy decides to help out. She reaches out to press the intercom button, this time setting it so that it only broadcasts to the control room. The Locomosolarites don't need to hear this.

"Well done, Doctor." She claps. "You've figured it out. All you have to do is..."

"Rewire the cables to the generator to stop the portal and then plug the sonic in and reverse..." he interrupts.

"The direction of the portal so the people currently in it come back," she says, finishing his sentence. "Everyone lives, well almost everyone. There's just one small problem with that."

The Doctor knows she's baiting him, just waiting for him to ask what clever trick she's pulled now. He obliges, asking "What?"

"If you do that, it's going to kill you," she sings gleefully. Her face falls as the Doctor's eyes darken. "Oh, I probably should've mentioned that before."

Missy watches as the Doctor scans the equipment, determining that yes, if he does follow through with his plan and plug the sonic into the portal and then use it the power surge will kill him. It won't be enough to kill him permanently, but certainly enough to force a regeneration, something which he isn't particularly keen on going through again so soon(even if he would probably get some nicer coloured kidneys).

He furrows his brow. There's got to be a way out. Missy watches intently, enthralled by the Doctor as he works. He'll figure it out, he has to, but in the meantime she gets to watch him do what he does best.

She's almost disappointed when it doesn't take him as long as she expects to figure a way out of it, but her disappointment fades the moment he does figure it out and she gets to witness his excitement at thinking he has bested her. He jumps up, moving his hands around and doing a little dance. Then comes the solemn moment once he realises that to save the people of Locomosolarem and save himself he will have to sacrifice his precious sonic screwdriver. She almost feels bad for him. Almost, just for a moment, and then she's drawn back to him in the present as she watches him save the planet and escape, albeit just barely. He truly is magnificent.

...

The Doctor stops to look at the security camera sitting in one of the trees by the TARDIS. He knows she's still watching. He's saved the planet, brought the people back and even managed to find the hypnotised King and return the place to normalcy. He knows the Master will move on soon, as always. There are more worlds to be conquered, more challenges. There's no fun in lingering. He thinks he is back in the good books of the Locomosolarites. All in all it's a pretty good outcome, but it's unnecessary. He's angry, sonic screwdriver-less and about to run away again to his solitary lifestyle, but he's got one last thing to say to the woman he knows is responsible for everything everyone has gone through today.

"Why? Why would you do all this?" It's a rhetorical question.

"Oh, Doctor," Missy says to the empty room. "Because I love watching you shine and you love saving worlds."

He truly is at his best when he is escaping from a near impossible situation and saving people. Admittedly this isn't one of her best world domination plans, not even top ten - she wasn't even really trying - but it was enough to get the Doctor's attention. She has achieved her true goal. If Missy can capture his attention even for a moment, even if it means destroying the universe one planet at a time, she will do it, just to see him, just to hold his gaze and know that he's thinking of her. She would do anything to have her friend back.

The Doctor steps back into his TARDIS, feeling a strange sense of regret in his stomach. He isn't sure why. As he walks over to the TARDIS console to set off again, he spies a brand new sonic screwdriver sitting there. Another present. He has a pretty good idea who it is from. This time he can't help but smile, his anger starting to vanish at the sweet gesture.

Missy watches him climb into his TARDIS, feeling the sadness and loneliness wash over her. She blows a kiss towards it as it dematerialises. She wishes he had come back to say goodbye, or even just to try to stop her from doing something like this again. In the end they both know that any attempt would be futile. She needs a challenge, something to conquer, just as the Doctor needs to run away in his blue box. It's how they live. That's not going to change and time soon, but at the moment their lack of proper farewell is inconsequential.

They will meet again.
