Only D have heads...P's don't
And because P's don't have heads...they don't think, just feel .. that why there P's...
P's are just empty voids waiting to be filled... and in Kerry case do to his close relationship with A's of the world he been filled by them so he now an P/A....
This is the classic lib arc...start of as a P that hang around with A's and end up swallowing the crap A's spew out and becoming a P/A
Oh good Lord!
