A/N: It's a work in progress, and the ending is at this point unwritten. That's not how I normally work, so I'm a bit nervous. Read on, though, I think what I've got so far is pretty good. Set shortly after Captain Jack joins the TARDIS crew in "Empty Child."

Disclaimer: I don't own them, or I would have made Chris stay on as the Ninth Doctor.

Chapter One: "It's Sonic!"

"Right then!" the Doctor exclaimed, clapping his hands together over the console. "Good day, we won! Where next? Go ahead, anywhere you want." He looked to his companion, Rose. She was normally just as excited by the thought of new places as he was, but this time she greeted his offer with a huge yawn.

"Wherever," she said as she tried to stifle it.

"You alright, Rose?" he asked.

"Oh yeah," she replied. "Bit tired from all the runnin' about, I expect. I think I'll just take a nap."

"A nap?" he asked disbelievingly as she headed off down the corridor. "Running about?" He would never understand apes, never. Save a world and now she was tired. She should be on top of the universe – he was! He shook his head and leaned back over the console, setting the TARDIS for another destination.

-----------------------

Rose bit back on another yawn as shuffled into the Control Room the next morning.

"Still tired?" the Doctor asked in amazement. "You've slept for hours!"

"I'll be alright after I have a cup of coffee," she assured him. "An' maybe some aspirin. My head's killin' me."

"No aspirin," he told her cheerfully.

"What do you do when you get a headache, then?" she asked.

"Don't get headaches, me. Time Lords --"

"Right," she cut him off. "If there's no aspirin, could you talk a little more softly?"

"You're really hurting, aren't you?" he asked, concerned.

"Yes," she said curtly. "Thanks for noticin'."

"Hang on a mo," he said, oblivious to her sarcasm. He pulled out the sonic screwdriver, tinkered with it, then ran it over her forehead. "That help?" he asked with a grin.

"Not really, no."

He checked the setting on the screwdriver and tried again. "Anything?" he asked expectantly.

"Nothin'," she replied grumpily. "I'll go and see if Captain Jack has anything'." She shuffled back out of the Control Room.

"Captain Jack," he scoffed. He should never have brought Harkness aboard; now Rose thought he was some sort of miracle worker or something. He turned his attention back to the sonic screwdriver to figure out why it hadn't worked on Rose's headache.
