I don't know, they could have gone all in one the Khionian culture and his past and it might have worked. Instead we got a wedding I didn't care enough about. Likewise, the plot of "an empty school over the holidays" could have worked on its own. As I wrote somewhere else, with a show including Paul Giamatti, I was immediately reminded of the Holdovers. Two students and Reno, would have been a great setup I think. Instead, we got some hasty character "development".
