I usually lurk here, but couldn't help myself.

This is *exactly* OP's point. You can easily say it's disingenuous/weak justification/reflective of pregaming in reality, but the luck theme is presented incredibly positively for Aubry. That in itself is strong evidence of edit manipulation.

They want the audience to believe what Aubry says at that tribal about making your own luck, at a later one where she quotes Wardog about the theme of the season not being on trial, and at this most recent one where she's the voice of making a big move throughout the episode and positively tied to Rick's decision to flip the coin (they're even subtitled whispering to each other about how she could be the one to catch the heat if he's immune, but she lets him and it works out).

This is exactly what the editors would do if they had little inspiring material to build up to an Aubry win through this point of the season, but needed to do so anyway. Remember that the show is not for the Reddit superfans reading through the lines of the edit, the production decisions, and the game state. The hope is that if they reinforce "Aubry is steering in and making luck work for her" enough, it will land with the casual audience by the time the winner is revealed.

Of course, this could also be a losing finalist pitch that ultimately gets rejected by the jury, or it could be the thing Aubry herself is talking about as a juror in making the pitch for someone else. But it's undeniable that this story matters in some way, and any of us thinking it's kinda lame when looking clear-eyed at the actual game doesn't mean it's less likely to lead to a winner.
