Veronica "Vern" Domingo got the solid five votes from the former members of the Naak tribe, ending her fight in the quest for the first Sole Survivor. On the other hand, Rob, with the additional one vote from the Black Pearl that Kiko gave him, got all the votes of the three remaining former Jarakays.
Earlier in the episode, Charisse won the Immunity Challenge where they would search for blocks of their assigned color and arrange them in the way Paolo showed them before the challenge started. Veronica was actually the first to gather all seven blocks but she had trouble arranging them in the correct way. Charisse, who seems to excel in mind-boggling stuff, was the first one to get it right, earning her the Immunity Necklace.
