I've been re-reading the HP books and I got to Prisoner of Azkaban (be still my beating heart. 'n is still the best one) and. at Christmas there's only 12 people around the dinner table. Trelawny comes along and Dumbledºre stands up to draw her a chair. She freaks out, I must not! When 13 people dine togethe _ the first to rise is the ﬁrst to dia!!!!! Ron had Scabbers in his pocket. Which means that mere wasn’t 12 people when Trelawny arrived. There was already 13. And Dumbledors stood up.
