If JK Rowling kills off a character in Book 5, will they come back as 
a ghost?

>From memory, she said in an interview that there will be more 
information about ghosts in Book 5.  And if she's just gone and 
killed a main character, maybe they'll become a ghost?

While I'd love to see a Snape ghost haunting the corridors of 
Hogwarts, I've long been concerned that Remus Lupin would be bumped 
off..  Since Remus is a favourite character of mine, I wouldn't mind 
so much if he could hang around as a ghost for a bit.
