In Harry Potter and the Deathly Hallows: Part 2, it was shockingly revealed that Snape has been working as a double agent for Dumbledore since the First Wizarding War. However, the character was tragically killed by Voldemort before Harry could uncover and reveal the truth about Snape and his friendship with the late Lily Evans (Harry’s mother). Snape has one of the most tragic stories in the series; however, little is known about his backstory.
