"Doctor!" Donna's yell rang through the corridors of the TARDIS. The Doctor dropped the spanner he had been holding where he had been working under the console. He leapt up, bumping his head on the console, and ran in the direction of Donna's room, skidding to a stop outside her door.

"What is it? Are you alright?" he called through the door.

"What have you done?" she yelled, yanking open her door. She stood there, hair dripping, towel clutched around her, and with what he supposed were soapsuds on her shoulder.

"What did I do?" he asked.

"Eyes up here, spaceman," she said, lifting his chin with her finger. "Why did you turn off the hot water?"

"I didn't! I swear."

"You knew I was taking a shower, and you thought it would be funny, did you? I'm not laughing, mister!" she continued, ignoring his interruption.

"No, no, clearly not. I didn't do anything, I swear!" he said. Had he? He had been changing the patterns of some of the circuitry. Had he moved the hot water connectors? "At least, not on purpose!"

"Well, you can bloody well go put it back, right now!"

"Just, let me have a look," he said, pushing past her into the room, and trying not to notice how little the towel actually covered. She smacked his arm as he passed by, but then had to clutch at the towel again. "Ow!"

"Hurry up!"

"I am!" he protested, moving quickly toward her bathroom. He reached in to turn on the shower, allowing the spray to splash over his hand. "It feels fine to me," he said.

"Well, it wasn't a minute ago!" she replied, standing next to him to put her hand in the spray. "That's weird," she said.

"Must have just been a glitch," he said. "Probably my fault. Sorry." He could smell her shampoo, and the soap lingering on her skin.

"Well, as long as it's fixed," she said, softly.

He reached up to brush his hand over her shoulder. "Better get the soap rinsed off," he said.

"Suppose you're right. Sorry about shouting at you." She shivered under his touch.

"S'Okay." He heard a drop of water hit the floor as it dripped from her hair.

"Are you planning to watch?" she finally asked, with a smile.

"What? No! That is, I'll just be outside. I mean, in the console room. Working!" he sputtered.

"Just don't touch the hot water controls, alright?"

"I won't. I mean, I didn't!" He ran his hand through his hair. "I'll just...go," he said, without moving.

Donna clutched her towel around her. "Well?" she said, raising her eyebrows at him.

"What?"

"Are you staying or going?"

"Is staying really an option?" he said, his voice squeaking at the end of the question.

"Depends," she said, smirking.

"On what?"

"On whether you're planning to watch...or participate." She stepped closer.

"Oh, well, you know me. Always looking for new experiences." He put his arms around her waist as she stepped closer still.

"Well, then, spaceman. You are wearing too many clothes. I hardly think that's fair, and we wouldn't want to ruin your suit." She ran her hand down his lapel, smiling up at him mischievously.

"Who cares about the suit," he said, pulling her close and kissing her. In the back of his mind, he heard the TARDIS give a self-satisfied hum.
