I was really happy to see Harry do that. I was ticked when he spit in McGonagals face.

McGonagal was very strict but fair. She would have been completely justified in "Chamber of Secrets" to have expelled Harry and Ron over the flying car incident but didn't.

Then after he used it, she gave Harry a hard time for using the Cruciatus curse on Carrow.
