The system does identify story threads (http://arc.quanten.co/showcase/series) - for eg, if you scroll down, you'll realize that there are two story arcs in that episode and that is typical for tv shows, there is a running theme, and then the arc for the season or episode.

The system identifies it, we havent started naming it yet, though we can at some point. I need to work with more showrunners to understand their thinking and process on it. Know anyone?
