AU of HBP. Narcissa never made Snape swear an Unbreakable Vow, and in the end, Draco decides to accept Dumbledore’s offer of sanctuary. But when Narcissa dies and Dumbledore declares his intention to create a soul-bond between Harry and Draco mainly to get rid of the Horcrux in Harry, Draco becomes enraged. He’ll use the soul-bond and the sanctuary Dumbledore gave him. But not exactly in the ways that Dumbledore anticipated.
