Sam responds, “Right, I have enjoyed it, but it’s been really hard.”

Sam asks, “So do you think me being friends with Nancy has put me off and in a bad position?”Farida nods her head in confirmation.

Sam says, “God, that is not good.”

Farida says, “If you align yourself with the wrong person you’ve… it’s just the way it is. You’ve already had the experience, where you nearly got chopped on the head, do you know what I mean? And that’s because of the person that you’re aligning yourself to and it’s… it’s just food for thought.”

Sam responds, “They’ll buy anything at this point, babe.”

Big Brother continues, “However, what they won’t know is that every AI judgement will actually come from you… The Housemates’ task will be to predict ChatBBT’s judgements when Big Brother asks them to line-up from most to least across a series of different categories.”

Sam says, “Let’s f**k it up babe.”

Disguised as ChatBBT, will the Secret Housemates cause a stir in the House?
