COMICMIX: With The Shepherd’s Tale , why is Shepherd Book the first character from Firefly to get a solo story? JOSS WHEDON: I’ve done a breakdown of the story. I think Jim Krueger is going to write the actual script. The biggest mystery of what we never got to tell is Shepherd’s backstory. Everybody knew there was something more than just being Shepherd in there. And poor Ron [Glass] came to me during the strike and said, “I’m going to another convention. You’ve got to give me something.” It’s been a number of years and they always ask [about Shepherd]. I said, “You know what, it has been long enough and this isn’t something I’m going to save for the sequel that may never happen, so we’ll make a comic book out of it.” Because it’s an interesting story, really. It’s the single most-asked question: “What’s up with Book?” And now we’re going to answer that.
