Just a guess - production staff.
Who goes to RI will be determined after tonight’s TC - the end of the show.
We should not see a RI competition until next week.
Then again I could be wrong and TC is in the second to last segment and the RI competition is the last segment.
So, everybody - look for the dark shorts.
If you have a lit lantern in one hand, do you really dig around for a flint?
