Kaylee looked sheepish for a moment. She had to remember that a lot of the people weren't from her time. None of them knew about the 'verse. Kyle was from earth, real earth, the original earth..
Course, Kyle also knew a thing or two about spaceships. Where as these guys? Who knew.
Kaylee bit her lower lip a moment and tried to think of how to explain it.
"I.. live on a spaceship." Yes, well, that wasn't helping. "I ain't from earth. I mean, I'm human like you guys are.. But earth for me.. well no one lives on it. Too many people, we found other solar systems to live in, and terraformed other planets. But I live basically in space.. in Serenity. The spaceship that is." Kaylee shrugged.
"It's pretty normal where I'm from. Don't mean'ta freak you out Mister." Kaylee smiled.
"Some of us never get used to 'atmo, like me. I'm an out in the black kinda girl."
