After witnessing a memory from Snape about Lily's and James' time as Hogwarts students, Harry gathers the impression that Lily hated James, but Sirius and Lupin assure him that she did not; they "simply got off on the wrong foot", because Snape and James hated each other, and Snape was Lily's best friend at the time, despite him sorting into Slytherin. Rowling confirmed this view when asked how Lily and James had fallen in love if Lily hated him. Lupin tells Harry that after James matured, Lily started seeing him in their seventh year. Rowling later echoed Lupin's words, describing it as James having to " down some of his more 'bombastic' behavior". They married soon after leaving Hogwarts, with Sirius as best man at their wedding.
