Toward the end of Harry Potter and the Sorcerer's Stone, there's a scene where Harry, Ron, and Hermione are about to break the rules and leave their dormitory after-hours to stop the bad guy from stealing a powerful magic artifact. Before they leave, though, they must face none other than Neville Longbottom, a rather bumbling, ineffective student in their class. "You're sneaking out again, aren't you?" Neville asks. "I won't let you. You'll get [our classmates] into trouble again." He fails to stop them, and Harry and his friends manage to stop the villain. But, surprisingly, at the end of the year banquet, headmaster Dumbledore gives the greatest honor to Neville. "It takes a great deal of bravery to stand up to our enemies," he explains, "but just as much to stand up to our friends."
Although Neville never becomes truly close with Harry, Ron, or Hermione, he still stumbled across two of the key traits of a friend or an accountability partner: the ability to recognize patterns of sinful behavior, and the courage to call the person out on them.
