He's a funny man, Dumbledore. I think he sort of wanted to give me a chance. I think he knows more or less everything that goes on here, you know. I reckon he had a pretty good idea we were going to try, and instead of stopping us, he just taught us enough to help. I don't think it was an accident he let me find out how the Mirror worked. It's almost like he thought I had the right to face Voldemort if I could.
J. K. RowlingMiss Granger, you foolish girl, how could you think of tackling a mountain troll on your own? Five points will be taken from Gryffindor for this,โ said Professor McGonagall. โIโm very disappointed in you.โ Hermione left. Professor McGonagall turned to Harry and Ron. โWell, I still say you were lucky, but not many first years could have taken on a full-grown mountain troll. You each win Gryffindor five points.
