What is the author's style in As Bees in Honey Drown by Douglas Carter Beane?

The flashback is a stylistic device used heavily by the author. The first time Beane uses flashback is in act 2, scene 2, while Evan is talking to Morris, the executive from Delta Records. Morris begins exposing to Evan the way Alexa cons people, and, rather than having Morris recite these lines, Beane brings Alexa into the scene. Although all three actors are present on the stage at the same time, Evan and Morris are in Morris's office and Alexa is at the Hotel Paramount. As Morris relates his knowledge of Alexa to Evan, Alexa is playing out a scene she and Evan had previously shared.
