In 4 of the 5 Tribal Council's that Michele attended she had her hair up and wore a jeweled headband. Only in Ep11 TC did she have her hair down and did not wear the jeweled headband exactly matching the Ep14 Promo.
Ep08 Tribal Council
Ep09 Tribal Council
Ep10 Tribal Council
Ep11 Tribal Council
Ep14 Promo
Ep12 Tribal Council
I agree the Ep14 Promo lighting makes it seem like a leaving camp scene in the late afternoon sun and Aubry wearing her sweater instead of blouse does not match the Ep11 leaving camp scene.
However we also know they film/stage these scenes multiple times and it is possible this was a scene they filmed and didn't use and asked them to dress differently for another scene.
I am starting to lean toward Final 4 leaving camp for TC. The promo department was careful enough to only include Final 4 scenes of the Reward and Immunity Challenge and I would hope they were not dumb enough to put in a scene of the Final 3 marching to Tribal Council.
Does that look like Cydney's hair down on the side in the Ep14 Promo? Because Cydney had her hair all tied up tightly in a bun on top of her head for Ep11 Tribal Council (see photo above).
