Did Chris ever talk about his book dedication to "Charlie"? At least to give some explanation, even a fake one. I know he always talks about his grandma and Hannah so it was obvious that some dedications were meant for them, but this?
He has never mentioned it. The plausible deniability is due to the fact that the dedication was made by the character Red and not by Chris himself. Just like Mother Goose dedicated her book to Lester.
