Divergent/Tone and Mood

"What the hell is going on?" the boy next to me shouts" (Roth 68) She had just chosen the duantless class and all of a sudden everyone is running.  This boy is freaking out because he has no idea what is happening.  Im really exited when reading this.  Its an exciting mood. This tone gives it confusion and chaos.  It made her really think about what she was doing with the dauntless.
