In "Harry Potter and the Order of the Phoenix", after seeing a scene from Snape's memories within a Pensieve of a fifteen-year-old James and Sirius bullying Snape, Harry agrees with Snape's assessment of his father's arrogance. According to Dumbledore in "Harry Potter and the Philosopher's Stone", however, James and Snape shared a rivalry, not unlike that of Draco and Harry. In addition, Lupin tells Harry that Snape "never lost an opportunity to curse James". According to an interview with Rowling, "James always suspected Snape harboured deeper feelings for Lily, which was a factor in James' behaviour to Snape." However, when Sirius attempts to lure Snape into the Shrieking Shack where Lupin stays during his werewolf transformations, James prevents him from entering the tunnel under the Whomping Willow, thus saving Snape's life; although – as Snape points out – this also saved James from expulsion.
