They usually get a merge feast in place of an RC at the merge. Gross nummies challenge this time is the IC, per the promo vidcaps (Probst standing next to immunity necklace). How that works for IC and individual immunity, no idea. But they do seem to be divided into two groups at the start:
Andrea, Corinne, Eddie, Erik, Malcolm, Sherri
Brenda, Cochran, Dawn, Michael, Phillip, Reynold
(Only six places at the challenge table, no one sitting on the already lost this one bench.)
Evil of JP to fill them up with a merge feast and then throw a gross nummies IC challenge their way, evil evil evil.
How does this one work?
And Brenda fails in her round.
