My prediction for Brandi is that she will assume she is now Madame Gao's favorite, will try to leverage that, and will get smacked down hard.
Chester is nasty as hell... I'm not used to seeing that level of violence on basic cable... but the glint of the sun off his plot armor is blinding. He magically knows stuff because he needs to know it for the story, and he is immune to all obvious consequences because he is Just That Big a Badass. (I mean, Shobnam's father is a major figure in international banking. He probably doesn't go an hour of his life without someone trying to contact him. And Chester has kept him locked in a cage for how long, with apparently no one suspecting or checking up on him?)
And Madame Gao... I get that she's a superheroine, having passed the "Great Exam" before she had her first period or whatever. But Master Zane is the unconventional combat instructor at a worldwide school for high-level assassins. Even Madame Xena there shouldn't have been able to make him look like a fool, standing there getting his ass kicked and then meekly allowing some bimbo to carve a letter on his face. Madame Gao's superior skills don't mean that everyone else magically loses theirs. There should have been a real fight there, Madame G should have taken a few hits. This kind of thing is hardly specific to Deadly Class, but it's something I wish filmmakers would get past. Even Wonder Woman gets hit occasionally.
Viktor is, I guess, as funny as anyone gets on this show apart from Brian Posehn. (Wonder what happened to him? Nothing good, probably... Chester is a Hollywood Psycho and has to kill everyone he meets just because.) It's been a while since I last saw a Gay Panic joke in a TV show. Not that it isn't perfectly appropriate for 1987.
