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).
Question: In the epilogue, Victoire Weasley and Teddy Lupin are referred to as cousins. How can they be cousins? Were either of Teddy's parents related to the Weasleys?
Question: Why didn't Dumbledore let Harry, and the others on their side, know ahead of time that he had asked Snape to kill him? Then they would have known all along that they could trust Snape.
Question: In Godric's Hollow, it shows James and Lily's date of death to be in 1981, which would mean these events are taking place in 1997 when Harry would be 17 and the original Harry Potter book would be set around 1991. Is this a mistake or deliberate on JK Rowling's part?
