Remus Lupin

At school, Remus Lupin was a prefect and always the more practical Marauder, often keeping best friends James and Sirius in line. Lupin first met Harry Potter when he returned to Hogwarts as Defence Against the Dark Arts professor. Lupin might have been a little shy, a little shabby and he tended to disappear at certain times of the lunar calendar, but he was a kind and excellent teacher and even taught Harry how to conjure a corporeal Patronus.
