The Doctor could explain it better. He knows how it all goes and I still don't...quite remember what happened between being human and then suddenly not.
The Nestene...it's an enemy of the Doctor. One of many and it made Romans from your mind for some...plot against The Doctor to keep him in a prison.
But because they used you...The Doctor said you weren't ordinary. Your memory was special because you grew up with a time crack. So when my 'duplicate' was made, my heart and soul came back from...from de-existing, as far as I can tell.
