My head-canon is that the reason no one ever translates for R2 is that he’s extremely insulting in virtually every sentence, not just to 3PO, but to everyone.
If Chopper is anything to go off of in Rebels, chances are most astromech droids are assholes. Hell, most A.I. on Earth seem to turn into flaming racists within like a day if left to their own devices. I’m sure there’s whole sections of code written in all these LLM AIs specifically to keep them from devolving into racist bastards. Chances are in the SW galaxy they just don’t even care about that (or it’s actively encouraged by the Empire).
There are lines where 3PO is like “I can’t translate that” so your theory is proven to be right
In the early scripts, R2D2’s lines are… quite interesting.
Fucking hell, he’s a massive fucking nerd.
THREEPIO: This is madness; we’re going to be destroyed.
I’m still not accustomed to space travel.ARTWO: The external bombardment does appear to be
concentrated in this area. The structure
has exceeded the normal stress quotient by
point four, although there appears to be no
immediate danger.THREEPIO: No immediate danger! You’re faulty. This
is madness![much later]
ARTWO: It’s not possible. We’re not built for this.
You’re nothing more than a dim-witted, emotion-
brained intellectual. Why you were created is
beyond my logic systems. Thanks to you, we’re
deserters, and will probably be destroyed on
sight. And on top of that, you’re going the
wrong way! All this filth is getting…It’s interesting how c3p0 is just these two characters merged into one.
Fucking hell, he’s a massive fucking nerd.
I knew I liked him. he also has some fairly perverted comments. usually those got replaced by fart-noises.
Wait, not everyone does this? I thought everyone knew R2 was a foul mouthed manipulative little shit.
