In an interview JK Rowling did with Emma Coad for ITV in 2005, she explained the Patronus as "a kind of spiritual guardian of sorts." And that's partly because of what he does. It is the protector, and you can protect yourself and other people you care about with a Patronus” (Quote). The importance of a Patronus and even more so, the importance of its form has been heightened since it was introduced in Harry Potter and the Prisoner of Azkaban. Harry's Patronus takes the form of a deer, which is exactly the animal his father could transform into. In Harry Potter and the Half-Blood Prince, Harry mentions that Tonks' Patronus form has changed. In Harry Potter and the Deathly Hallows, Snape's Patronus is a doe, just like Lily's. Throughout Rowling's series, she introduces her readers to the Patronus as a guardian, but she continues to develop this idea throughout the series to make it a symbol of an individual's identity and a symbol of his deepest desire. With a Patronus as a substitute for self, Rowling gives in to the idea of ​​an individual's action, because even if one longs for a protector, one must ultimately act to save oneself. Throughout the Harry Potter series, the importance of the Patronus grows. as the reader learns more about the characters. The word Patronus is introduced into the Harry Potter canon in Harry Potter and the Prisoner of Azkaban, and Rowling quickly establishes the Patronus as its guardian. As Professor Lupine explains to Harry, a Patronus is "a kind of anti-dementor – a guardian that acts as a shield between you and the dementor" (237). Rowling introduces this new vocabulary term to readers and gives a minimal definition via Professor Lupin. Later in the book, Harry finds out why... in the middle of a paper... in the form of his Patronus. Rowling's use of the Patronus as a manifestation of an individual's identity represents the idea that although we crave a protector and seek someone who will save us, ultimately we must rely on ourselves- same. Harry needed a protector in the form of his father. At the end of Prisoner of Azkaban, he waits for his father to appear, to cast the Patronus charm and save him and Sirius. While he waits, he becomes aware of his own capacity for action: “no one was coming to help him this time – and then it hit him… He hadn't seen his father – he had seen himself -even” (411). As much as Harry wished for his father, even tried to justify that his savior was his father, he knew he had to act. Rowling in the end here supports Harry's agency, he had to save himself and he continues throughout this book and the entire series saving others even though
