Owen was teaching Nosy numbers again, and having much better luck this time, using bottle caps instead of grapes.
“How’s it going?” Ianto asked, bringing them coffee.
“Pretty good; Nosy can count up to ten already and we’ve only been at this for an hour.”
“That’s nothing, I’m teaching it addition and subtraction now. Watch this. Nosy?” The Fluff looked at Owen expectantly. “What’s ten minus two?”
Nosy thought for a moment, then squiggled itself around into a figure eight.
“Correct! What is five plus four?”
Another squiggle formed a nine.
“It’s a mathematical genius,” Owen grinned.
