Viewing the evidence

Kneasy:
Not too keen on the theological metaphysics, myself. Particularly
as Jo is setting her own rules and definitions. Makes it tricky.
In my own mind I consider Vapor!Mort as anima - a disembodied
life force. It has potential, will, drive, etc, but no substance and 
so is powerless to act independently. Not sure my construct can be
torn along the dotted line into neat, self-contained segments, so
I'm probably wrong.

Dung:
Some canon to add to an extremely late reply, which I was absolutely 
certain existed but was unable to find for ages (sorry for the 
delay).
 
HBP UK p470:
"The seventh part of his soul, however maimed, resides inside his 
regenerated body. That was the part of him that lived a spectral 
existence for so many years during his exile; without that, he has 
no self at all."
