Kaylee Frye and Simon Tam
"You want to hike up a potentially dangerous volcano?" Simon blurted the words with very little urge to take them back. Of course she'd want to do that. Too much time with the likes of Mal and Zoe was what that was.
Still. It would get him some time with Kaylee. And maybe he could even avoid boring her with useless volcano facts. So long as they didn't die. "I guess we could probably squeeze that in before we leave."
