Completionism

The Listener is the main character of a videogame. Cicero doesn't know this, but he knows there's SOMETHING special about her. He's not quite genre-savvy enough to pinpoint a completionist when he sees one, but he's loyal enough to help in any way he can. (Lots of meta humor. Slightly one-sided CiceroxFemDovahkiin because, come on. Seriously.)
