The Doctor had spent a better part of the morning looking up whatever he could on the flickering planet, fixated in front of the console as the Master came and went, bringing tea and toast and occasionally a kiss, or a snog, simply because he was bored of the Doctor's interest in the place already and would not sit still for very long. He didn't like hanging around doing nothing.

"Shouldn't we just... y'know... go there?" he asked after a while when he reappeared and wrapped an arm around the Doctor's waist, tilting his chin to make him look at him. "I'm sure you know most of what there is to know about-."

"No," the Doctor sighed, shaking his head reluctantly. "No, we need to know what to expect."

"But-."

"Please."
In a huff, the Master stormed away, leaving the Doctor to his dull and fruitless work. It seemed he'd been doing more of this lately, researching and looking into a planet before gallivanting off to cause trouble. Perhaps it was just now that he was on board, things were different. He seemed protective, clingy if anything and by his standards, it was fine; it was like having a little Doctor guard dog. Though the reasoning behind it couldn't be all that complicated. It was just like Theta to get attached, and his death and resurrection was probably too much for the poor little Doctor to handle. He needed him! Oh, what a thought, the Oncoming Storm needing a little Master and mayhem in his life. Which is why he'd saved him from the Time Lords, saved him from falling into the Time Lock. And oh, the look on Wilf's face when they'd kissed! The Time Lord practically purred at the thought, humming as he made a mess of the kitchen, ignoring the warning growls of the TARDIS.
He returned to the console room bearing melted cheese and bread and tomato soup, all shoved together into a bowl. Quite good, mind you, but he plopped down next to the Doctor, chewing and smacking loudly.
"There are better ways to get my attention, love"
"Yeah but this is fun"
"It's annoying"
"Oh hush, I've done worse before!"
The Doctor smiled a little at this, and lowered his glasses to look up at him. "You're impossible"
"Yeah I know" He leaned over and stole a kiss from the bespectacled wonder, who seemed quite pleased at the small distraction.
"Come on. You've got to learn this stuff too, it's important"

-

"Okay, let's go over this again" the Doctor mumbled, flattening out the Master's hair as he fussed about him. It was a nice planet, and he wasn't very well going to have the other going out in rags and trashy clothes, so something more civilized. He smiled as he let out a huff, pulling at the jumper. "Galtahh is...?"
"Second capital of Theacrima Galaxy"
"Good, and?"
"And what?"
"What else, it's not just the capital, love"
"That's all I need to know."
The Doctor sighed and tutted at him, hitting him upside the head as he moved away to fix his own tie.

"To be fair," the Master huffed, crossing his arms over his chest. "You told me all this while I was still half asleep an-"

"Well, listen now," the Doctor cut across him, taking his hands and meeting his gaze. "Galtahh is full of planetary security and anything out of the ordinary from their lives is taken note of. In a rather serious way. But legally they are not allowed to kill, so it would be a long sentence and probably very painful. No laws against torture. Very boring but pretty planet so you are to be on your best behavior, and do not under any circumstances get involved with politics" he smiles, letting go of the Master, who responded with a repeat, crossing his arms over his chest like a petulant child.
"Well what if I get bored?"
The Doctor only smiled, leading them out of the wardrobe and into the echoing halls of his beloved ship, arms in arm as per usual. And to think just ten years ago... just ten years of fighting and clawing at each other to make it work, and now... They couldn't function without the other properly. Like bits of magnets, repelling and pulling the other together. Odds and ends, pole to pole, keeping the other grounded. And besides, flying the TARDIS with two people was a lot easier than just the one, and for that, the Doctor was grateful.
Stepping out into the console room, the Master tugged at his new clothes and sneered slightly. "I don't like gray. It's a rubbish color, there's no character to it at all!" The Doctor simply shrugged, throwing him a coat before shrugging on his own. "And how come I have to wear this, when you get your normal clothes!"
"Because mine always look good"
There was a discontented mumble behind him as the Master pulled on his 'regulation Time Lord Overcoat', a wool black thing as per his request, and followed the Doctor to the front door. "Ready?"
"As I'll ever be..."
The Doctor smiled, hand to the other's face as he pulled him into a small kiss, pushing open the door and leading him out.

He wasn't halfway out the door when he stopped, frozen in place. Which gave the Master no room to squeeze by, and he forcibly pushed the Doctor to the side to get a glance of what t was that appalled him so.
There was nothing. Absolutely nothing. All those stories about overcrowding and the rushes for food, the people lining every inch of ground they could were floating away like the wind that howled through the sky scrapers, still humming and alive with artificial sunlight. The only sound in this wasteland.
"...what was that about security?"
"Shut up"
