Okay, so we all know that Snape never used the potions book, he wrote down the instructions, and harry always failed potions class. BUT, when harry used SNAPE’S book with annotations and the same instructions snape would have given in half blood prince, he was a genius in the class. Which means if Harry Potter wasn’t so petty and just paid attention during class, he would have done really well in potions class. I find this absolutely hilarious.
