Here's another gem from the Phoenix Journals, PJ24 pg 107. On the topic of clones:
The most obvious clue to replication is that the "new" entity will always be fresh and more youthful than that which you will have seen just prior to replacement. This is why you must have control of all your media in order to pull off the subterfuge. Even under strict control of photography and make-up techniciansthe replication will often differusually in reversal of character habits or muscle actionsi.e., there will be a reversal of a "lop-sided" smilethusly, "talking out of the other side of the face", so to speak. The reversal of these traits is all but impossible to eliminate.
