Seems genuine enough,.first girl anyway. The 2nd one was basically wagging her tail when it was her turn to talk but maybe he just had the one shitty daughter.

But -if you were gonna fake it, probably you would kill some Americana for the authenticity. That guy getting killed or never existing in the first place is ultimately irrelevant in addressing whether or not Butler was a genuine article, a false flag, or some homunculus of one within another, which is likelier than a supra-govt cabal trapping him in a kill box with some shitty kid to get the shot.
