Jo says she planned for a long time to make the last word of the Harry Potter series be "scar." At some point along the way, she changed her mind and wanted the final words to read "All was well." Fans might take comfort in thinking that all was well with Harry and his friends, but only Jo knows for sure what really becomes of them.
Jo: [The characters] are all still in my head. I mean, I could write. I could definitely write an eight, ninth, 10th. I could, easily.
Oprah: You could. Will you?
Jo: I'm not going to say I won't. I don't think I will. I loved writing those books. I loved writing it. So I feel I am done, but you never know.
