Blue Water Bottle matching the vidcap of the men walking
Blue Tennis Shoes
So probably the Blue Tribe walking to/from a Challenge?
Someone from the Blue Nuku tribe on the Left
Michaela from Red Mana tribe in the Middle
Troyzan on the Right?
To me that looks like Andrea as Sierra Dawn-Thomas is REALLY Tall
Someone has Blue painted Nails and a Thumb ring so I think this it the Blue Nuki Tribe
Is that Zeke carrying the Blue Water Bottle with Hawaiian or camouflage shirt?
This scene seems very bright and sunny so I think most likely walking into a challenge or possibly walking from a challenge but probably not walking to TC
