I think there must be a “Henchmen’s Code” much like the “Pirate’s Code” that they talked about in the first Pirates of the Carribean movie.  Of course it wouldn’t be a formally printed list of rules, but more like a set of guidelines….

The important thing here is that VIXX is going way past the line when she decides she’s going to force the henchmen to work for her, whether they like it or not.  I suspect that means that now the guys don’t have to stick to the ‘rules’ any more either.  What does that mean in how they deal with their new problem?  You’ll  find  that out in Chapter 7!
