Kogs, yeah if it was just Mirna, I wouldn't trust anything. But we also have Danielle saying that they talked about being yielded and bad it felt.
Then we have Dustin & Kandice with a slightly different story, but one that does coberate defintely part of the story.
When they are doing their after check in confessional (and it stil looks like they have just recently checked most likely before the others arrived) they talk about how multiple teams think they were yielded in season 10.
So that does at least confirm part of Danielle's and Mirna's comments.
Now D & K say they never confirmed or denied, and just didn't talk about it. That seems very unlikely.
Ie it is hard for a person to jump to any conclusion if they didn't talk about it at all.
Now its possible that they said something like this, damn I hated the Yield in our season, it made us feel so bad when it happened and we got in last and were hit with the 30 minute penalty.
That doesn't say they were Yieled but puts a real negative spin on the emotional connection to that event. And I could see conversation (especially from Danielle's point of view being the only team member this season to be yielded), and they including themselves into that catagory without technically saying they were yielded.
But they absolutely had to say something.
And they are aware that teams plural feel that they were yielded, this implication seems to have at the very least not been corrected (they aso talk about that and laugh, and day no they aren't going to tell them the truth), so it seems maybe they might have encouraged that belief.
So yeah, even at best this would fall under the "Lie of ommission" catagory. BUt I wouldn't be surprised if the BQ's helped people believe that it did happen that way, without directly saying yes we were yielded.
