Jeff at the time and Jeff now might have two different views, but
according to this, he's thrilled with what happened. Since shot in the dark has been introduced, 8 players have tried and got "not safe" and the one person who got "safe" didn't need it as she didn't receive any votes. According to Jeff the original idea was something that anyone could do, at a cost, to flip TC on the spot, and it finally worked. In the link, he even says he had to keep a straight face when he read it before he revealed it, so maybe that's why he looked grumpy.
Or it's that scratchy throat he seems to have every TC after he spends hours yelling through challenges?
Anyway, Good Canadian Boy Kaleb is saved, and I'm happy. And Austin was so right wanting the sandwich over the amulet, and J paid the price of that stupid decision along with trying to hide her Dee vote by telling everyone to tell Sifu she voted for him. That and perhaps her general grumpiness put her in place to be the quick back up (rather than Emily) when the Kaleb vote fell through.
Also another shout out to Austin for choosing the right time to upgrade an advantage to an idol when he and his bestie had immunity and there was the max number of votes in the game to ensure his vote wouldn't be missed by others or affect the outcome.
On that point, Kaleb's position is working well for Austin and Drew, who I think are the other biggest threats to the end as they plow through with their own alliances and strategies apparently unnoticed by most of the others, who are focussed on getting out people they don't like or who slighted them or who, in Kaleb's case, seem too nice or strong.
Would be fun to see an Austin-Drew-Kaleb-Emily final I think.
