... a Circuit Overseer?
That first scene, with the searingly tense, sinister, faux-friendly visit and "conversation" over the glass of milk... the loaded-gun smile, and ominous bookbag... Something about his manner made think of some just horrific shepherding call.
(and no, I am not literally equating COs/Elders with Nazis... I am just saying the tone was reminisent, to me, of such meetings.)
