- This book will explain why some people can become ghosts while others cannot. One of the important characters will appear as ghost in this book . (This may have already been answered, at least to a certain degree, in Order of the Phoenix Chapter 38, where Nearly Headless Nick explains that wizards who are afraid of death often return as ghosts.)
-Rowling wrote the last chapter of the book some time ago, to give her an ending to work up to. The last word of the seventh book, according to Rowling, is currently "scar" , but she has also said it may change, along with the whole last chapter she has previously written. This last chapter contains details of what happens to each surviving character:
"This is the thing that I was very dubious about showing you... (T)his is the final chapter of book seven. This is really where I wrap everything up, it's the epilogue. And I basically say what happens to everyone after they leave school - those who survive - because there are deaths - more deaths coming. It was a way of saying to myself, 'Well, you will get it, you will get to book seven one day. And then you'll need this!' So I'd just like to remind all the children I know who come around my house and start sneaking into cupboards that it's not there anymore - I don't keep it at home anymore for very, very, very obvious reasons. So there it is." – J. K. Rowling
-There are indications that at least two of the main characters will die. In a June 2006 interview about the previously-written ending, Rowling stated that:
"One character got a reprieve, but I have to say two die that I didn't intend to die...A price has to be paid. We are dealing with pure evil...They go for the main characters, or I do".
