Despite any lack of psychic powers, or seeming magic, or seeming anything unusual about the human girl -- except an extreme amount of timedust, void 'stuff' and a subtle hint that she'd been through hell itself; apparently more than once -- she starts singing for him, as if she knows exactly what he's looking for.

"It's a world of laughter, a world of fears!" she cheerfully bops her head along to the song.
"It's a world of hope, and a world of tears,
There's so much that we share,
That it's time we're aware--!" she doesn't finish though, just looks at him expectantly, like she thinks it'll come back to him and he'll know the next line.
