Truth or Consequences
In part 1 we first see 'Truth or Consequences' appear in a scrolling text message on the tablet in UNIT HQ and we're told that "the encryption system has already been hacked." The implication being that the Zygons have hacked it.
This is confirmed when the two schoolgirl Zygon leaders are forced to normalise and are killed: the killer appears, gives his ultimatum and finishes by saying: "Truth or Consequences".
So how did the Zygon rebel know that phrase was written inside the Osgood boxes? Or how did someone know to write that phrase in the box?
