They should've gone with a different story from the book and left out Miss Trunchbull. She'd be replaced by Principal Trilby (the person at the end of the book) and the musical would be about him helping her with her intelligence. But the story that Matilda tells would be about an acrobat and an escapologist being in two different circuses and they fall in love with other. They couldn't be able to see each other much because they're in two different circuses but one day it's announced that the two circuses would be combined. The acrobat and escapologist would perform an act together. They permanently stay in one circus, get married and have Jennifer as their daughter. As for how Miss Honey is the way she is, she was bullied.
