I wouldn't really bet on that. Chekov has always been an impressionable hothead, Sulu has maintained his cool even under pressure and mental duress, and the effects of this * entity (love the novelverse abbreviation!) were subtle - McCoy didn't go stark raving mad, he merely started using Nazi arguments against Kirk's more reconciliatory tones.Because Sulu was in his right mind in that scene, and Chekov clearly wasn't.
Just reinterpreting it, and IMHO in the more logical fashion. Kirk clearly doesn't know the first thing about Chekov's family; he's relying completely on Sulu's account. So his "testimony" doesn't count for anything at all. Sulu's statements would be in line with what * does to people: it doesn't just make individuals go berserk, it makes individuals create strife in their environs. And Sulu insisting that Chekov is mad is effective in creating strife that draws Kirk into the fight despite him having been resilient so far.If your takeaway from those exchanges was that Chekov actually had a brother, you're misunderstanding the episode.
...But was she Orion?Indeed, Marta was fully sentient, albeit mentally disturbed.
Hers is the only case of the green paint actually visibly rubbing off, when she tries to kill/secude/both Kirk. Her insanity might well be defined as her believing she is an Orion animal woman, and painting herself accordingly!
The one possibility remaining after all is said and done is that Orions market their female slaves (coming from the naturally green Orion species) as "animal women", either because that sells, or because any woman thus marketed is rendered "animal" somehow. Whether this entails removal of sentience, in which case the puppet masters of the ENT episode were pre-animalized, or some other procedure we have yet to be told of, the opportunity for interesting interpretations still remains.
