Harry started throwing some herbs and liquids and animals and such into his cauldron at random. He figured that if he put ENOUGH stuff in there, he'd happen upon a combination that'd kill him.
Just then, Snape suddenly appeared in Harry's room. "So, Potter," Snape said with a sneer. "Trying to get some unnecessary practice in?"
Harry ignored him. "You know, Potter, I did not give you permission to do this. Not that it looks like you're following any sort of directions all that clearly..."
Harry continued to ignore him, hoping that he'd go away. "Not only am I going to deduct points from Gryffindor for this," Snape said, "but I'm also going to ask that you are expelled? What do you think about that?"
IF HARRY CONTINUES TO IGNORE SNAPE AND SIMPLY DRINKS THE POTION, GO TO CHAPTER 16
IF HARRY CONFRONTS SNAPE, GO TO CHAPTER 19
