You enter the TARDIS, and the first thing you hear is an angry Scottish voice, shouting at something, followed by the sounds of hammering. You carefully make your way to the console, and see large, black boots sticking out from underneath, which makes you smirk; he's almost always working on the console, at least twice a week.
"Prooooo", a very familiar voice tries to say, but it's glitchy; you look up to see the holographic interface wearing your face, and using your voice.
"She's been doing this for the last two days," the Doctor says, his Scottish brogue so heavy you know he's in a bad mood. Without even thinking, you grab a flathead screwdriver, the most ordinary thing you've seen him use, and wait with it in hand, reaching towards him.
"[Y/N, can you hand me...? Oh. Yes, that," he says, and you smirk at the confusion in his voice; he's still not use to you being almost in tune with him to the point you can sometimes anticipate what he needs.
"Why not just build her an avatar? A body, biosynthetic?" you ask casually, sitting down in a jump seat nearby. He stops moving, rolling out the dolly he uses when working under the console, to stare at you; you can't be sure, but it's a cross between confusion, and awestruck.
"Why?" he asks, dumbfounded.
"Easier to repair, you can create a personality to download into it, and link to her. And it tends to be easier to interact with. It's essentially an AI body people an interact with, that's all," you reply, and have the satisfaction of watching his face light up with the "ah ha" moment.
"Ok, I'll give you points for the idea, but do you have any idea how difficult that is?" he admits, almost grudgingly.
"About as difficult as building a TARDIS from scratch?" you reply, smiling innocently. The TARDIS herself beeps in amusement, and even the Doctor smiles.
"Well no, not THAT difficult, but it's not easy. But, there is some merit to the idea. I'll have to think about it. But for now, can you..." he says, only to be interrupted by you handing him the sonic spanner. He raises an eyebrow, and smirks sarcastically at you, which you respond with your usual broad grin. He rolls back under the console, leaving you to watch the hologram glitch on the visual aspect.
"This is going to be a while. Would you make me some tea, please?" he asks a little distractedly.
"Sure. Cookies?" you ask, and chuckle when he snorts. His only response is to wave the spanner at you, then disappear under the console.
You head to the kitchen, and start the tea, grabbing a package of chocolate chip cookies, and a tray. Sitting on a kitchen stool, you wait patiently for the tea to finish, imagining what form he might use for the avatar, and whether he'll name it or not. You smile fondly as you imagine his face as he designs the exterior form, almost a child in a candy shop; it's not even mean, or demeaning, it's because he would enjoy that aspect of creation. You load up the tray with kettle, cups, spoons, sugar cubes, and cookies, and return to the control room. He rolls out from under the console, and you help him up with one hand, carefully balancing the tray in the other; he perks an eyebrow up at that, grinning almost mischievously, and you just smile.
"Thank you, [Y/N, I needed a break anyways. Ok, what's THAT grin for?" he asks as you both head to the upper walkway, carefully sitting in the armchairs; you blush slightly, wishing he hadn't seen the amused grin gracing your face.
"It's nothing, just letting my mind wander," you reply, perhaps a little too quickly. He merely raises his eyebrow again, but says nothing, grinning knowingly, and takes a sip of his tea.
You both enjoy the quiet break, enjoying the company without needing to break the quiet. Well, as quiet as the TARDIS can be, beyond the many mechanical sounds she makes as part of normal function.
"Do you really think I should do it?" he asks suddenly, breaking the silence. You glance over at him, but he's staring at the console, and looks like he's thinking hard.
"Well, I think it would make things easier, but I know it's not an easy thing, even for someone as ridiculously brilliant as you," you can't resist saying, and giggle when he smirks, and quickly adopts a "well of course" pose, simply for your pleasure. He grins broadly, and winks conspiratorially at you.
"Yes, yes, it's nice to know someone finally notices ny superior intelligence," he jokes, making you throw a cookie at him. He catches it, and his eyes twinkle merrily.
"Ooo, just what I needed," he says, biting into it with relish, making you roll your eyes, and laugh. He's not always this jovial, especially as frustrated as he was when you first arrived, so you are quick to take advantage of the opportunity to joke around with him.
"If you do, may I help with exterior design?" you ask hopefully, which makes him glance at you, a little surprised at the question.
"I suppose so. Sure," he says after a moment deliberation.
"But nothing too awful, it needs to be something everyone can interact with," he chides, wagging a long pointer finger at you, to which you smirk.
"No, this isn't "Weird Science", I'm not going to give her G sized attributes," you joke, and laugh when his eyes widen at the image; his face is a play of equal parts fascination, and horror.
"Do that, and I'll ban you from the TARDIS," he finally remarks, and shudders.
-What do you mean by G sized attributes- the TARDIS asks you, causing you to laugh so hard you start tearing up; the Doctor simply groans and covers his face with one hand.
"It means extra large breasts, milady," you wheeze out between laughs, and notice the Doctor is trying so hard not to laugh, but has also started blushing slightly. Aww, look, he's embarrassed by the fact that he was even briefly intrigued at the idea, you think silently to yourself.
It takes a few minutes for you both to calm down, and you grin broadly at each other.
"Just for that, I'm going to do it! It'll take some time, though. I'll have to work on the body first, then I can build the program to put into the brain. I may actually need to create a program to help make the external aspects, including skin, eyes, etc," he says, face neutral as he thinks hard about what all needed to be done, and what should be done first.
"I know I'm not a robotics engineer, or anything like that, but I'll help as much as I can," you offer, with a small grin.
"Thank you. I don't think you can help with the internal stuff, but I'll need your help with the external design," he says, smiling brightly at you.
"Might I suggest we eat a good, hearty meal first? And perhaps wait until tomorrow to start, so we can both get a good night's sleep, and maybe a hearty breakfast?" you ask.
"I don't need sleep, but it's a good idea. Maybe I will sleep tonight, to be sure. And a hearty dinner will definitely be good. Maybe we could order Chinese?" he asked brightly, making you laugh.
"You and your Chinese food! And your crisps..." you say, chuckling, pulling out your phone to order the food.
20 minutes later, and you both were chowing down, and watching the Matrix trilogy, just because you could. You knew tomorrow would be rough, so you chose to enjoy the companionship, and the joking, and the good sleep at the end.
