They mentioned "tweaks a few phobias", perhaps Nat overcame her fear of heights. (Well, she would have to, if they won.)
P.S Thanks Peach for moving it to the correct thread. My apologies.
I watched the promo during Survivor last night in slow motion on my HD TV & DVR setup. If you step through it, you see Nat with tears rolling down her face - eyes practically closed, probably back pressed to one of the uprights, but apparently at the top of the crane. They also show 2 sequences of team bungee drops. One is clearly J/T with J on the left (facing the crane) - you can see the faces clearly. The other, filmed from above, is N/K with K on the left. You can't really see the faces well for N/K, but based on clothing (not pink) and blonde on a different side (so not J/T), it has to be N/K.
So Nat powers through her fear of heights!!!
As far as I am concerned, N/K deserve to win. Both faced major hurdles and powered through them.
