Harry Potter and the Deathly Hallows
Synopsis: Snape's fifteenth memory: [Dumbledore] reveals to Snape that Harry himself is a [Horcrux], and that he will have to give up his own life in order for Voldemort to be killed. Dumbledore asks Snape to tell Harry this when the time is right - when Voldemort fears for the safety of Nagini - and leaves Snape angry that after all he has done to save Harry, Dumbledore concealed from him all along that it was only for his eventual death. Snape also reveals his [Patronus]: a doe, the same as Lily's.
