The Art of Self-Defense

During lessons, Henry tells Casey that he thinks he is getting promoted to black belt. Sensei does a promotion ceremony where he upgrades Casey to a yellow belt. When Henry brings up the other promotion, Sensei says he is promoting someone to black belt, but it is another member, Thomas (Steve Terada). Later on, Sensei notices Casey performing less actively than before. They talk in Sensei's office, where Casey brings up the mugging and how he is terrified of men larger than him, and that he wants to become that which intimidates him. Sensei invites Casey to check out the night classes. Casey goes to the night classes and finds Henry there, even though he was not invited, and he also thinks Casey betrayed him by showing up without telling him. Sensei has Henry go up for a demonstration, and Sensei brutally snaps Henry's arm at the elbow. In another instance, Anna spars with Thomas and puts him in a headlock. While unconscious, she proceeds to smash his face in with her fists as retribution for him getting a black belt before her. Sensei then disqualifies her from getting a black belt. He later has Casey cool off in the maintenance room, which is also Anna's changing room. She gives him a massage to cool off, but refuses to talk to him about why she attacked Thomas. Casey gets a message from Grant saying that he needs to come back to work since it has been two months. He starts to utilize an assertive demeanor, which really makes him come off as a dick. He punches Grant in the throat after he invites Casey to have dinner with him and his wife, and then he talks to the guys in the break room and insults them before appearing to get them on his side. Naturally, he is fired, but Sensei offers him a position as an accountant for the dojo. Casey starts to curry favor with Sensei and the other students (save for Anna) by applying himself more, as well as getting everyone regular belts that match their karate colors.
