Yall I was rewatching Superman and I noticed smth, is that mr terrific says the COMPUTER guys he knows are legit, not the linguists. Could imply that the message is definitely real but that it’s not translated correctly? Terrific doesn’t mention the linguists, so probs no confirmation either way in whether Clarks bio parents are telling him to help Earth or take it over.
One could also interpret their message as well meaning, in that they genuinely believe they are a higher species and it is so normalized they don’t find the statement weird or unkind, or realize it sounds like a threat.
That or im reading too much into it.
