At the morgue, when Clint is about to be embalmed, his head moves. Earl, the embalmer, says it is just a reflex and that he has seen it before. As embalmers can attest, dead bodies are known to belch, fart, twitch and, on rare occasions, sit up. This is due not to "reflex" but because of gases moving through the body and muscles contracting as chemical changes begin.
