The question is not asking for speculation — as would obviously not be accepted by most here.1
I really think most of the answers are subpar. I'm opening this topic here to discuss whether my assessment is correct and to hopefully get some attention to, if necessary, improving the answers.
At time of writing this, there are 5 answers.
The accepted one has many reviewers and downvotes that seem to agree with my assessment: pure fanon, methinks.
Another offers probable and believable suppositions for why the line was included in the movie — but seems rather simplistic for me: as if it didn't even take the line at face value but really misinterpreted it.
Another answer is obviously unsubstantiated, but upvotes tell me that many drive–by voters agree. If its purported quote actually exists, then I think it would be the best answer and I'd upvote it.
One answer seems plausible, but it in no way makes an effort to support its claim. Fanon, but better than the accepted one.
Of course, there is also my answer, but if I had problems with it then I'd either edit, delete, or ask them in a different question.
So, prior to me flagging the answers for review, is there anything else that can be done?
Maybe I am making too big a fuss out of these answers …
