This is the first time I'm doing a challenge like this, so I hope you all like it! The prompt for this chapter was "mistletoe". Leave prompts in the reviews if there's anything you'd like to see over the next 25 days! I've got about ten more spots to fill on my prompt list.

The Doctor was startled, to say the least, the day he walked into the console room and discovered the time rotor wrapped in fairy lights. His jaw dropped slightly and his brow furrowed as he looked around the room – the support struts were wrapped in garland and string lights, baubles dangling from the high coral branches.

"What in Rassilon's name…?" he grumbled to himself, looking up at the ceiling in question. The TARDIS just happily hummed at him, delighted to be all dressed up. The Doctor opened his mouth to respond to his ship, but stopped when he heard a sound. A stifled giggle, from across the room, but it still caught his attention.

"That's taking it a bit far, don't ya think, Jack?" Rose said.

"Aw, come on, Rosie, it's just a bit of holiday fun."

"Okay, okay," Rose said, breaking out into full gales of laughter.

The Doctor crossed the room to watch his companions, who remained unaware of his presence. He leaned against the console, crossing his arms with an amused smile.

Jack was smirking as he busily attached a bunch of mistletoe to the top of the TARDIS doors. He stood on top of a ladder, held in place by Rose, who was grinning brightly, her eyes sparkling as they reflected the fairy lights that lit up the room.

"What's going on here, then?" the Doctor asked loudly, startling Jack, who yelped and fell backward off the ladder. Rose looked up in surprise, smiling at the Doctor with her tongue in her teeth.

"We're decorating for Christmas," she said, folding her hands in front of her, the picture of innocence.

"I gathered that much," the Doctor said. "Wreaking havoc in my console room."

"Ow," Jack groaned from the floor.

"All right there, Harkness?" the Doctor asked him, rather amused by the whole situation.

"Wonderful," he muttered, picking himself up off the ground and brushing himself off.

"The TARDIS likes it," Rose said matter-of-factly. The ship flickered her lights in agreement. "See?"

Jack held up the mistletoe that he hadn't gotten the opportunity to properly fasten to the door.

"We're getting into the spirit, Doc. It's Christmas!"

"We're in a time machine," the Doctor pointed out.

"Don't even, mister. I've been keeping track with my Earth calendar. It's December first!" Rose said.

"Rose…"

"We've been working really hard, all morning," Jack said.

"And it looks so beautiful in here with all the lights…" Rose continued.

They looked at him hopefully, and the Doctor shook his head and threw up his arms in surrender.

"Fine," he grumbled. "But I'm not helping. And no mistletoe, Harkness."

"Aw, Doc…"

"Are you sure, Doctor?" Rose teased. She took the plant from Jack and waved it in the Doctor's face. "Could be fun."

If the Doctor were human, he would have blushed. Instead, he stared at her blankly, his mouth opening and closing with no words coming out. Rose stepped closer to him, holding the mistletoe higher, so it was just above their heads. He heard Jack snickering, but all he could focus on was Rose's mouth as she leaned closer to him.

She pressed a quick kiss to his cheek before she giggled and backed away. She tossed the mistletoe back to Jack and darted out of the room.

"Come on!" she called back. "We've got to do the library next – I saw some stockings earlier, we could hang them above the fireplace!"

Jack grinned at the Doctor, who still looked rather shell-shocked as he stared after Rose's retreating form.

"Still want me to get rid of the mistletoe, Doc?"

He laughed when the Doctor scowled at him.
