I thought that the metal 'contraption' hanging in the tree to Missy's left at the Challenge and the one hanging in the tree to Keith's left in the first pic might be two of the same thing.
And, if they had been, then I think that we would have had to consider the possiblity that Keith was (a) at the Challenge and (b) unhappily out of it.
But Tribe says 'Nope' and I'm fairly certain that his eyes are much sharper than mine.
