According to TV Tropes, she's named Kalista in what it termed "an upcoming novelization." The only such book I'm aware of is David Lewman's junior novelization, and a quick peek at the first chapter does not identify Zach's girlfriend by name. Does the name get mentioned later (like, say, Zach thinking about her), or is "Kalista" total fanon with no basis whatsoever?
