“This is a weird one… Ron Glass [who played Shepherd Book] was going on some ‘Serenity’ fundraiser cruise. He knew that, as usual, they were gonna be asking him the whole damn time about Book’s back story, how he came to be who he is – one of the big mysteries of the show and the film. So he emailed Joss, said, ‘What the hell, gimme something to tell them.’ Joss wrote back, and copied me, saying that we were gonna do a graphic novel answering all the questions. That is literally how I found out.”
