Part 21: Christmas Cleaning

"What are you doing, Missy?" he asked her. The Doctor had become very suspicious when she had disappeared into the depths of the TARDIS a few hours ago and decided to look for her. He found her in his bedroom, holding a broom.

"I'm cleaning the TARDIS," she announced and kept on sweeping the floor.

"I can see that. The question was rather why you're cleaning the TARDIS."

"Because I want everything to be nice for Christmas. Don't worry, the console room is next."

"But the TARDIS can clean itself."

Missy snorted in disgust. "Well, she's not doing a very good job at it. And besides, you chose the settings for the amount of cleaning she does. Have you seen the layers of dust all over the place?"

The Doctor ran his index finger over one of the book shelves and inspected in. "Seems clean to me."

"That's because I just cleaned there!"

The Doctor shrugged. "I don't see what your problem is. The dust has never bothered anyone. Not even Clara."

"This is the ultimate bachelor TARDIS," Missy explained, "Of course it has never bothered Clara, she never had to live in here."

The Doctor raised an eyebrow, curious about where this conversation was going. And never in his life had he expected what he was about to hear.

"If I'm going to live here, the place better be clean," Missy stated and started to look around, apparently pleased with how clean his bedroom now looked.

"Wait, hang on," the Doctor interrupted her inspection, "Since when do you live here?"

"Do you maybe want some fairy lights around your bed? It could look like stars," Missy beamed at him.

"Don't change the subject," he warned her.

Missy started pouting. "Oh, honey, try to keep up."

She took the broom and the rest of her cleaning supplies and headed for the console room. The Doctor, still baffled about the latest developments in his living situation, followed her.

"Missy, wait! You know you don't actually live here, right? I never said you could live here!"

He heard her mutter something that sounded like "Silly Doctor", but he couldn't be entirely sure. Before he knew what was happening, Missy had handed him the broom and he found himself helping her clean the console room, wondering when exactly he had agreed to let her move in.
