Re: AFT NACELLE (Spoilers)
I guess the assumption is that Khan should know what he's talking about -- and that if some error is made when issuing a basic threat, it tends to diminish the power of said threat; even when the other characters proceed as normal (because they're as dumb as Khan is).
Even when I know what I am talking about, I constantly switch words if they are close in meaning or in sounding, I conflate terminology and often speak gibberish. OK, Khan is superintelligent, but even then, some of my and my colleagues' mistakes made it into our work jargon, so maybe he's repeating someone else's mistakes. Or maybe he still slips sometimes.
