Or... Kirk was confused because what he knows of the actual Gorn from Starfleet reports conflicts with what he's experienced in the episode.Damn. I was wrong. "Woman" is BAD you say?
No no no no no. The "breaking canon" is not that the Gorn no longer look like Ted Cassidy in a lizard suit. (YES I know he wasn't in the suit! This is NOT my first rodeo. I've BEEN to Vasquez Rocks. For NEARLY HALF AN HOUR!)
The breaking of canon is Kirk's befuddlement at "something called a Gorn". From what we've seen so far (and who knows what's coming next) the very name "Gorn" should have produced a reaction more like "HOLY Q - er, HOLY TRELANE! That's the thing that nearly killed SAM!" Or even "Hey! Gorn! Those buggers are always sneak attacking human bases and outposts. Doesn't that just figure!"
For all we know Ted Cassidy In a Suit was some misshapen defective Gorn that would fit perfectly in line with the SNW Gorn life cycle. Totally fine.
And I don't even care about the breaking canon bit. It's just annoying when there are people (some of them even WOMEN*) who say "Oh no, it all still lines up. It's fine." For one thing, if it all lined up we wouldn't have the writers telling us "Story is more important than canon."
Hey, isn't it cool that Orions have science vessels?
(* The reference to "women" here is in a purely satirical context. Star Trek has a diverse fan base with obsessive nutters of all races and sexes.)


(And IMO, the actions the Gorn were able to take in TOS S1 Arena pretty much indicate they must have encountered Federation ships and personnel prior to their assault on Cestus III. About the only question I would have is why if Federation Command knew about the Gorn, it wouldn't disseminate that information more widely throughout the fleet.)
