Other mistake: As in the first movie, Bob can't speak as his mouth is sewn shut, and because of this he barely makes any audible sound. So how is the lower body of Chares Deitz able to speak? And, like the magician's assistant who died when she was cut in half, shouldn't the other half of him be in the afterlife with him?
Suggested correction: This is a question, not a mistaken entry. I suspect that in this afterlife the ability to speak is considered important if you don't own a mouth anymore, so it is made possible to speak without one. If it's sewn shut, however, tough luck, figure it out (he can cut his mouth open any time he wants). As for the body parts that were not with him, it's possible the magician's assistant took her lower body with her, and Charles didn't know he could do that with his other body parts.
