Harry's mom (mum) died for him and that's the only reason Harry was left alive
This is quite literally the most pathetic explanation to why he is still alive. If you were told you cheated death because your mother died for you would you be satisfied enough with the sense that made? I can't believe how many people seem to be content with this joke of an explanation
And what about this Avada Kedavra curse that finished Diggory off? How are we to take Voldemort seriously if he doesn't have the balls to use the same thing on Potter
