When Duncan pulled out tea bags, Regulus was also both intrigued and cautious. How did anyone read tea leaves this way? Not that Regulus was good at reading tea leaves, to begin with. It was more the principle, or... something like that.
But before he could work out how to ask that, the toast popped up.
He startled a bit when the toast came back up. Who expected toast to just pop up at you from a muggle box? But then, curiosity winning over, he leaned back in to examine the toast. It was... toast, alright. He had so many questions about toast now, too. How did that metal box with slots know how to do that?
When he looked back at Duncan, it was maybe the new angle, but the light caught the man's eyes and they reflected a color Regulus was not used to in humans.
Too many stimuli at once had Regulus tongue-tied for a moment.
"Uh... no," he finally was able to say, straightening away from the toast, and trying not to make a deal of noticing Duncan's eyes. "My family had house-elves, cooking was house-elf work."
Regulus looked away, thinking about Kreacher, his house-elf, and how he must be fairing without him. Which was probably terrible, his mother and father never treated the elves with any kindness.
"My mother would never allow me to learn house-elf work."
He looked at Duncan, working up the courage to ask. "Do you have magic?"
