As they pull away from the crater, Charlie's head swivels, trying to keep it in view as long as possible. As the helicopter swivels to finally put it out of sight she seems to shake herself from her reverie. "Wow," she breathes. "You were right."

And then things settle back to something approaching normal for her. Charlie looks where Reno points and listens to his explanations and his stories and asks occasionally ridiculous questions ("Is it actually made of icicles?") and generally has a whole lot of fun and isn't shy about letting him know.

"So where are we going next?" she asks, still glowing a bit from her experience over the crater.
