Although J.K. Rowling has stated that the Sorting Hat has never gotten a decision wrong, arguments can be made about certain characters fitting into more than one house. After all, the series presents us with some very complex witches and wizards.
Has the Sorting Hat made a mistake?
11 SEAMUS FINNEGAN: RAVENCLAW Rumors have run rampant for years that there are 7 mistakes made by the Sorting Hat in the Harry Potter franchise, but creator J.K. Rowling maintains that the Hat never made a mistake.
What happened to the Sorting Hat?
The Sorting Hat, now animated, was able to sort and divide the students into the Hogwarts Houses, and continued to do so for a millennium, passed down to each new Headmaster or Headmistress of the school. When not in use, it is placed on a shelf in the current Headmasters or Headmistresss office.
