Here, I am confused again. I do agree that Terri is in all likelihood gone from that body, however the body still moves involuntarily. If the body functions at all, it means nerves are still working. If nerves are still working, doesn't that mean on some level the body would experience pain?
If she could feel pain, they wouldn't have done this, don't you think? However, it's a good question, and one I will look into.
