Shortly before the triad sealed their bond, Headmistress McGonagall asked Remus if he would consider coming back to Hogwarts to teach at his old post of Defense Against the Dark Arts. Initially he declined saying that he needed to focus on his job at the Ministry, but when Minerva offered him his own private floo, the day off before and after the moon, and relieved him of his Hogsmeade duties, he relented and accepted. In the months between, he worked harder than ever, and werewolves were eventually offered the same legal protections as regular witches and wizards, and thanks to the generosity of the former children of death eaters, the Wolfsbane potion was fully funded and free of charge for anyone that needed it.
