"I'd just... never met someone who didn't know what an air vent was before." Which is a little silly for her to get confused about, if she thinks about it, considering all of the other new things she's run into so far. Not knowing what an air vent is should be like... the least weird thing on the list.

She shrugs. "Uhm. They're just sort of... man-made metallic tunnels put into buildings to pump hot or cold air to different rooms? But the ones on my ship are big enough for me to crawl around in, and I like to go there when I want to be alone sometimes," she explains, not knowing exactly why she's even explaining this, except that she'd brought it up in the first place and it feels only fair.
