Jayne was pretty sure he could figure it out. It couldn't be that complicated, right? But if he broke it, he didn't want Lily or Jaime yelling at him. Besides, he figured one of them would be down soon enough.
"Pro'ly, yeah. I've never done it before myself, but I ain't never had to make it any warmer down here. Figure it's best to leave it to people that know how t'use it," Jayne decided.

But he could at least go look at it, right? No harm in that. Deciding that was how he'd swing it, Jayne cocked his head in the direction she'd pointed and started along that way ... where he'd probably just stare at the thing and decide not to touch it for fear of overheating the place or breaking the dial somehow - or something.
