And Harry knew that she cheated to get him on. So really, there should have been a playoff to determine who got the spot of Keeper, Ron or Cormac, since the last goal (which Ron got and Cormac didn't, thanks to the spell) was invalid.

I wish that someone would ask Rowling why her allegedly good characters cheat so much. And why on earth all the allegedly good wizards don't look that much better than the evil ones.

But, as I've never once seen a question asked of her in an interview which reflected badly on her work, I suspect that her handlers would ensure that she never heard such a question.
