Right on. I would like to find out more about Book though. His prior life is an interesting mystery. Flashbacks are generally cliche'd, but I would be happy if they happened to meet someone who knew Book and could tell a tale about him.
And of course River would have to have her "moments" where she goes completely insane and kicks major butt all over the place...
And maybe if Serenity were to happen to get into trouble and in danger of being destroyed...
And maybe Mal could walk in on Inara being a companion to another girl...
And Jayne shoots up a bunch of stuff and acts all tough...
Damn, I think I might have to bust out the DVDs tonight!
