After watching Harry Potter and the Prisoner of Azkaban I am a bit confused. The whole of first part was regarding Cyruis Black after Harry to kill him so that Voldemor could return. Then when we got to the scene where he was with the teacher and just about to kill him. Why doesn't he kill him and why do they suddenly become frienRAB. I thought he wanted Harry dead so that Voldemor could come back?
Did I miss something?
