First interesting thing is that the head stayed alive despite being deattched from the body, is this evience of some sort of soul?
No, I don't really think so. Now, "They Keep Killing Suzy," where Suzy was walking around talking without any kind of impairment despite the face that the back of her head and most of her brain was missing, that was evidence of a soul. Which made her and Gwen's conversation about whether there's an afterlife later on a little strange.
