Professor Severus Snape: No! Don't kill me!
Professor Albus Dumbledore: The prophecy did not refer to a women. It spoke of a boy born at the end of July.
Professor Severus Snape: Yes but, he thinks its her son! He intends to hunt them down now, to kill them. Hide her, hide them all. I beg you.
Professor Albus Dumbledore: What will you give me in return, Severus?
Professor Severus Snape: Anything.
