Prompt: Clara, from the 1890's, sees a computer for the first time.

...

"Doctor?"

"Yeah?"

"What's this?" Clara asked pointing at the contraption.

"What's what?" He asked from underneath the console.

"This." She insisted.

"What?"

"Just come up alright! My god!" She snapped, losing her patience.

"Alright alright, no need to shout!" The Time Lord said, getting off his swing and coming up the stairs while Clara rolled her eyes.

When he came up next to her, she silently pointed at it again.

"Oh. It's the scanner." He told her, waving a dismissive hand over it.

"A what?"

"A scanner. You know, it.. scans things." The Doctor explained unhelpfully.

She shook her head, confused.

"It's like a computer screen."

"A what?" She furrowed her eye brows in confusion.

"Blimey! Never heard of a computer screen! What are you from the 19th -" The Doctor stopped, as if to ponder for a moment.

Clara already knowing what conclusion he was going to reach, she leaned against the console, waiting for the penny to drop. She was always looking at him like he was the dumbest time lord.

Which he was, in her humblest opinion.

"Oh." He said, a bit uncomfortable by his realization. "Right."

Clara smiled patronizingly, nodding her head to him like he was a five year old who just learned how to count.

"We have a lot of work to do, then." The Doctor said to himself, looking around his very very advance time machine with the very advanced technology.
