"I'm working for Cybernet Electronics," the Doctor said. "Mind if I step in?"

"Of course not," said the man. "James Cooper, and you are?"

"Ah, John Smith," he said at once, an automatic response, even after years of disuse. "Pleasure to meet you."

"The same," he replied, leading the way into a small sitting room. "Marsha!" he called. "We've got a guest!"

A woman came into the room, drying off her hands with a dishtowel. "So sorry, sir, we've only just cleaned up from lunch."

"Oh, it's no problem," the Doctor said, waving a hand. "I'd just like to ask you some questions about your experience with the Cybernet products."

"Lovely," said Marsha. "Marsha Cooper."

"John Smith, nice to meet you. So sorry to be all about business, but I have to ask, what products have you gotten from us?"

"Oh, let's see," said James. "We've got a stereo, a laptop..."

"Don't forget the phones," Marsha called, having vanished back into the kitchen.

"Oh, yes, the mobiles, all three of us. And Linsey's music player and headphones."

Headphones! "Could I talk to Linsey?"

"Sure." James stood up, walked across the room, and shouted up the stairs, "Linsey!"

"What?" an irate voice called back.

"Come down here, please!"

"I can't hear you!"

"Just a moment," James said apologetically.

"Oh, no problem," the Doctor repeated. James climbed the stairs and shouted, "Linsey! Come downstairs, someone wants to talk to you!"

"Alright," Linsey shouted back. She came stomping down the stairs, her headphones pulled down around her neck. "What do you want?"

"Your headphones are from Cybernet Electronics?"

"Yeah. So?"

"You like them?"

"If I didn't, I would get new ones!"

"What do you like about them so much?"

She shrugged violently.

"Come on, I'm not stalking you," he joked. "I was just hoping to know what's good about them."

"Look at them yourself," she said, and threw them at his head before stalking back upstairs.

He picked them up. Surreptitiously, he pulled out the sonic screwdriver and sonicked them.

Metal shot up from the earpieces, forming half a square. He hissed through his teeth, glanced around, and slipped the headphones in his pocket. He dug around until he found another pair of similar headphones, but ones that were definitely not from Cybernet Electronics.

If anyone noticed the difference, he never knew. "Could you fill out this survey?" he asked James. He waited impatiently, then snatched the survey back when the man was done. "Got to go, lots of people to talk to!"

He ran out the door. He didn't have time now for any other surveys. He had to get right back to Cybernet Electronics, find the head man, and figure out what the hell was going on here.

He was in such a hurry that he didn't notice the girl in the blue jacket who walked past him. She climbed the front stairs of another house and banged on the door. Nor did the distracted Doctor see Donna Noble walk up to the house on the other side of the Coopers', knock politely, and start asking questions.

All he had time to do was the one thing he was best at, the one things he'd practiced for centuries. He ran.

A/N: Oh, no! What are they planning this time? What about poor Donna, caught up in all this? Will she remember? What will happen if she does? And is Rose ever going to notice to Doctor running around? Find out later today on DDWFFBC!
