Potions was a bit different though. It was the last class of the day, down in the dungeons. It was about twice as cold, but with the fires beneath the cauldrons on I was already starting to sweat. I was talking to Hermione when Professor Snape walked in making the class go silent. He walked to the front glaring at us as he went. As he got to the front he picked up a clipboard and started roll call. He paused when he got to Harry's name.
