Harry Potter: What Lupin's Patronus Is (& Why He Hid It)
In Harry Potter and the Prisoner of Azkaban, Remus Lupin (David Thewlis) teaches Harry (Daniel Radcliffe) how to conjure a Patronus charm, but his own Patronus is never seen — here's why. The Patronus is important to a witch or wizard's identity: Harry's is a stag (like his father James' Patronus), the Weasley twins (James and Oliver Phelps) both have magpies (hinting at the UK saying «one for sorrow, two for joy»), and Snape's (Alan Rickman) is a doe, which symbolizes his lifelong love for Lily Potter. In Lupin's case, the answer is an obvious one: a wolf.
