Or better still, since how this magical technology works is totally 
undefined, he didn't *wake up* in the scanning room, he just lay there 
or sat there while he was scanned, as we do when being X-rayed, then he 
got up, had a cup of tea, and went on his way out the same door he 
entered. The copies all experience something other than that: an abrupt 
lurch of location, or a moment of confusion, or find that 18 years have 
passed if they were grown from a reprogrammed somatic cell, etc.
