Question: I don't know if there is a definite answer to these two questions, but I would appreciate any guesses. 1. Why did Voldemort try to honor Snape's request to spare Lily's life? He gave her three chances to stand aside and let him kill Harry. But if she had actually taken the chance to live, Snape would have pursued her (Dumbledore later asked Snape "[James and Harry.] can die, so you can get what you want?"). Why would Voldemort try to help Snape get into a relationship with a Muggle-born woman? 2. On a similar note, why did Snape think that he had any chance of being with Lily - if she lived - after his master killed her husband and son?
Question: At the end of the third chapter, Petunia hesitates as though she wants to say something to Harry before she leaves, but she apparently changes her mind. Has J.K. Rowling ever revealed what she almost said? (I know that the movie has a deleted scene where Petunia mentions Lily, but that may not be canon).
