Throughout the episode, they constantly talk in unison while discussing strategies, which disgust Courtney. After a while, Sierra starts to see Cameron as Cody, the boy whom she's been obsessed with for a long time.

Before Cameron could correct her, Gwen shot him multiple times.

At elimination ceremony, they both believe that Jo will be eliminated unless Jo can make the others to vote for Heather instead. Sierra's insanity finally slip and she no longer believes Cameron exist, seeing him as Cody. She then offers him a foot rub, something that Sierra used to do to Cody.
