Remus Lupin was never bitten by a werewolf as a child. Instead, he was born a Metamorphmagus. At the end of his second year teaching at Hogwarts, already fraught with the events of the Triwizard tournament, Professor Dumbledore gives Lupin a special assignment: help a young, unorthodox Auror named Nymphadora Tonks after she is bitten by a werewolf.

Inspired by the chapter in Deathly Hallows where Harry meets with Dumbledore at Kings Cross and one of my favorite quotes from Dumbledore. Set after the Battle of Hogwarts. Tonks and Lupin get a chance to be together before they move on to their "next great adventure."
