Has anyone else noticed that the pattern that Prefects are selected is pretty inconsistent. Prefects are selected every two years or so usually once the Prefect has graduated, but also after a Prefect becomes the Head Boy/Girl. It goes from even numbers to odd numbers, but shouldn’t it stay just even or odd numbers? Dumbledore was a Prefect when he was a student (sorted in 1892j). Decades later, Lupin was a Prefect even though he was sorted in an odd number (1971). In Hogwarts Mystery, our character could become Prefect and they were sorted in 1984, but Cedric was a Prefect which starts going odd numbers again up to Ron, Hermione and Draco. Is that because maybe a Prefect became the Head Boy or Girl, but shouldn’t the next even number become the new Prefect, not go into the odd numbers? How does choosing a new Prefect even work?
