Clara Oswald always knew that being short would come in handy for something. She was less than thrilled that 'something' turned out to be the ability to fit under the sink to fix the leaky pipe. She supposed she ought to be more specific in her haphazard mental rambles.

At least the infernal dripping had ceased. She gave one last tweak with the wrench, then started to wriggle her way out from under the plumbing. A familiar wheezing, groaning noise filled her small flat and Clara bolted upright in surprise, banging the crown of her head against a protruding metal valve. The pain was instant and shocking.

Clara reached up to touch the top of her head hesitantly, and her fingers came away coated bright red. Very slowly, she slid out from under the sink and stood on shaky legs. At the first movement of her head, blood streamed down her face. She was trembling violently as she grabbed a dishtowel and hastily mopped her face before pressing it to the top of her head.

"Clara!" a familiar voice called testily from the direction of her bedroom, "Come on, we're going to the grand opening of the biggest library in the universe! It's safe, I promise - the Vashta Narada haven't hatched yet! Clara?"

Clara leaned heavily against the kitchen sink. Her hands were coated in blood, and her shirt was spattered as well. She thought vaguely that she should get some ice for her head.

"Where are you hiding, Clara? Come on - biggest library in the universe! Millions of books. You'll like that." He was behind her now, in the doorway of the kitchen. "Clara? Leave the damn dishes, why don't you? I'm taking you to…Clara?"

She turned slowly, and the Doctor thought his hearts might stop at the sight of all that blood.

"CLARA!" He crossed the tiny kitchen in two steps. The hand that gripped her arm was strong enough to bruise, but the fingers that tipped her face up to the light might have been handling fine porcelain. "What's happened? Who did this?" There was barely contained fury in the Doctor's voice as his eyes scanned the room for signs of intrusion.

Clara opened her mouth to speak, and a couple of tears trickled from her eyes, accompanied by a small sob. "No…it's not…there's no one here. I was fixing the sink, and I sat up too quickly. Hit my head on…something under there."

He masked his vast relief in tones of immense irritability. She was alert and upright. Her pupils were even. Likely it was just a minor scalp wound. Nothing to worry about.

"That was a stupid thing to do," he said finally.

"You startled me!" Another small sound that might have been a laugh or another sob escaped her lips, followed by more tears.

"Come on," the Doctor said gruffly, wrapping an arm around her waist.

"What…where?"

"To the infirmary, to make sure you haven't damaged yourself too badly. Can't take you anywhere looking like this. The local pudding brains will think I'm an ax murderer."

The medical scanner proved his assessment correct - a small laceration, easily mended. "How are you feeling?"

"Bit of a headache. Can I take a rain check on The Library? I'm knackered."

He grunted noncommittally. "You might want to take a bath, while you're at it."

Clara whirled, one eyebrow raised.

"You bled all over my deck," he reminded her.

The TARDIS emitted a soft series of chimes and burbles, but it wasn't quite clear if she was admonishing Clara for the mess, or the Doctor for his manners.

So, yeah…weird things happen to me, and I turn them into stories. You should all be used to this by now.
In case you're wondering, YES, minor scalp wounds DO bleed that much.
