Once upon a time...I had already defeated my Harry Potter and the Chamber of Secrets game for the Playstation 1 twice. Since I knew exactly what to do, I decided to play the game a little out of order the third time. As you may know, Snape yells at you when he wants you to gather potion ingredients. He also yells at you when Malfoy steals Neville's Rememberall. He yells at a third point in the game, but I can't remember why..... He just likes to YELL!
So anywho, I rearranged the order in which I did everything, and when I finished, all of a sudden, not one... but three Snapes appeared out of no where, surrounding me and shouting at me all at the same time for the three different reasons!!!! That was around the time the game froze and never worked again.
My warning to you: If you piss off Snape, do it in the correct order -__-'
