This episode was produced before "Ace in the Hole", but it aired much later. This is why Terry has no knowledge of Cerestone and acts like this is his first encounter, while in "Ace in the Hole", he knew what it was.
This episode finally reveals why Terry spent three months in Juvie. His criminal record had been alluded to in "A Touch of Curaré", "Revenant", "Rats" and "Eyewitness".
