..but it's funny to think that the barrier makes 3 distinct appearances in TOS, a series not exactly focused on or known for continuity or "returning elements."
Can we
please let this "TOS wasn't very good at continuity" myth die already? TOS had better continuity than most shows of its era.
- There's the offhand mention of Christopher Pike as the Captain directly preceding Kirk in command of the Enterprise in "Mirror, Mirror."
- There's the
Organian Peace Treaty, mentioned in "The Trouble With Tribbles," "A Private Little War," and "Day of the Dove," that called back to "Errand of Mercy," the first episode with the Klingons.
- There's the fact that Spock mentions that his father was an ambassador in "This Side of Paradise," and when we meet Spock's father Sarek in "Journey to Babel" the next season, he's an ambassador who just came out of retirement. (Yeah, both episodes are by the same writer, but it still counts.)
- There's
George Samuel Kirk, briefly mentioned in "What Are Little Girls Made Of?" before appearing in "Operation - Annihilate!", and he's played by William Shatner in a half second appearance as his corpse.
- There's the fact that
Lee Kuan was mentioned twice as a despot from Earth's history.
- There's two separate mentions of the
Axanar Peace Mission, in first and third season episodes.
- There's Sulu's mention of
"Janus VI, the silicon creatures" in the third season episode "That Which Survives," a callback to the first season episode "The Devil in the Dark."
- There's Bruce Hyde's character name in "The Conscience of the King" was changed from "Lieutenant Robert Daiken" to
"Kevin Riley," the character he played in "The Naked Time," when he was cast in a second guest part.
- There's a similar effort to call Barbara Baldavin her previous character's name of
"Angela" when she reappears in "Shore Leave," although unfortunately they'd already shot a scene where Kirk calls her character "Teller" by the time they made the change.
- There's the 1967 memos from DC Fontana and Bob Justman published in
The Making of Star Trek (pages 163-165 of my 1975 paperback edition) where they discuss the various starship names they'd established in a year and a half's worth of shows, including the ones mentioned as destroyed, in an effort to be consistent with the names in the future.
- And as you note, there's WNMHGB's
Galactic Barrier being mentioned and shown in "By Any Other Name" and "Is There In Truth No Beauty?", shows from the second and third seasons respectively.
None of these are the actions of a show that doesn't care about continuity and consistency. On the contrary, these examples show that
the makers of TOS cared about this stuff, because they realized that continuity references like this added to the believability of the
Star Trek Universe. Yes, they made mistakes and they changed their minds about certain stuff (the
United Earth Space Probe Agency, anyone?), but they got continuity right way more than they got it wrong. And keep in mind that this was
ALL in an age before VCRs, when the only way to rewatch an episode was to wait for it be rerun or hope that the series went into syndication.
So can we please stop pretending that continuity in the ST Universe somehow didn't exist until TNG premiered in 1987? This bit of "accepted wisdom" is just flat-out
WRONG.
Gary was a bit of a jerk even before the power got to him. I wonder if this influenced the kind of entity he later became.
The fact that Mitchell aimed the "little blonde lab technician" at Kirk shows that he always had control freak tendencies and was a bit of a prankster. Those qualities just came out in a more malevolent way after his encounter with the Barrier.
And I still can't get over how Kirk managed to ultimately kill Gary...simply by dropping a ROCK on him?
This ambiguity helped form the basis for John Byrne's sequel story,
Strange New Worlds.
It's actually pretty inconsistent. The grey only really seems to disappear during the fight. I'd chalk this up to a production/continuity error rather than the grey being a manifestation.
Mitchell's hair gets increasingly grey over the course of the episode as his power increases.
