First episode to feature Clayton as Gatling's political advisor, Pete as his P.R. director, and both of which replaced Gatling's top aide Taylor (with no mention of his departure).
The cast change adding Clayton & Pete was never explained, they just appear as established characters.
Rene Auberjonois and Ethan Phillips would both go on to appear in the Star Trek universe.
Rene in Star Trek: Deep Space Nine (1993) as Security Officer Odo,
Ethan in Star Trek: Voyager (1995) as Neelix the chef.
Both were much nicer characters that here,
Pete talks to his ex-wife in Tahiti who says it is "6:30" while the time at the mansion is "2:30". Tahiti is GMT-10 making it 5 hours behind Eastern Standard (GMT-5) so 2:30 AM EST would be be 9:30 PM Tahiti, 2:30 AM EDT (Daylight) would be 8:30 PM Tahiti, and 2:30 AM PST would be 12:30 AM Tahiti. This adds to the mystery of which state Benson takes place in a time zone in the middle of the Atlantic; with this logic the state would be GMT-2.
