The sisters Bellatrix Lestrange and Narzissa Malfoy seek out Snape, who lives in a Muggle neighbourhood in a street called Spinner′s End. Wormtail lives there too. Narzissa has a request to make of Snape, but Bellatrix wants to advise her against doing that. She doesn′t trust Snape and wants to know why he is still a teacher at Hogwarts and lots of other things, but Snape can justify himself with some good arguments. Narzissa asks Snape to help her son in completing an order from the Dark Lord and she wants him to look after Draco, as her husband Lucius is jailed in Azkaban. Snape swears to do that by making an Unbreakable Vow with Bellatrix as the Bonder.
